Joe Gebbia, the nation’s first-ever chief design officer, is planning to reshape federal government websites. Calling for delightful websites, the new America by Design initiative calls on agencies to modernize the interfaces that serve everyday citizens. Signaling a new era for government websites, agentic AI may provide the key to unlocking the rapid transformation required to meet this challenge.

The Foundation: A Brief History of USWDS

The cornerstone of this transformation is the U.S. Web Design System (USWDS). Launched in 2015, USWDS was created to provide a shared set of design tools and user interface (UI) components for federal agencies. According to the USWDS history, the project was born from the need to reduce design debt and create a consistent appearance across federal websites. Beginning with a small library of buttons and forms, USWDS eventually evolved into a robust ecosystem used by hundreds of federal projects to ensure accessibility, mobile-friendliness, and trust.

The Product Mindset: Meeting User Expectations

Modernizing federal applications is about more than meeting a set of requirements. Service delivery experts know delivering a delightful user experience requires a fundamental shift in strategy. At Karsun, we advocate for a Product Mindset.

Users expect a seamless experience. Government applications should work across devices. They should meet evolving expectations such as the integration of chatbots. A Product Mindset asks delivery teams to consider not only users’ needs today, but also their future needs. It builds in feedback loops to continuously track and ensure expectations are met. Its modernization and digital transformation that delivers applications designed for every next, ensuring they remain resilient and adaptable using not only design best practices but secure, modular, digital architecture.

ReDuX: The Bridge to the Future

Bridging the gap between legacy systems and delightful, yet compliant, interfaces is a monumental task. This is where the ReDuX platform provides a revolutionary AI-powered solution.

ReDuX uses agentic AI to ensure modernization efforts align perfectly with user intent. By taking user demos as an input, ReDuX analyzes real-life behavior to craft functional requirements that reflect how people actually use a service.

Today, ReDuX incorporates the USWDS among its input during code generation. This ensures that every line of code produced adheres to federal design standards by default. Furthermore, because ReDuX can ingest any reference material provided, it is future-proof. When USWDS evolves to the next era of web standards, ReDuX can meet the challenge, optimizing applications to new standards as they emerge.

The path to better service delivery doesn’t have to be slow. With the power of agentic AI and a Product Mindset approach, federal agencies can transform applications faster than ever before.We invite you to learn how ReDuX can help your agency deliver delightful websites that honor the mission and respect the user. Let’s build the future of federal digital services, together.

For the last decade, microservice architecture has been king. Breaking down massive, monolithic applications into small, independently deployable services revolutionized how we build and scale software.

But what’s the next step?

We’re on the verge of the next major evolution, one that infuses our systems with intelligence. We’re moving from a world of reactive microservices to one of proactive micro-agents.

This isn’t just a change in buzzwords. It’s a fundamental shift from building systems that wait for commands to building systems that understand goals.

The Now: The Reactive Microservice

First, let’s look at the microservice as we know it.

A microservice is like a specialist at a desk with a phone. It’s an expert at one specific task such as checking inventory, processing a payment, sending an email. It’s highly efficient, but it’s also dumb. It does absolutely nothing until someone calls its API and gives it a very specific, rigid command.

• It’s Reactive: It waits for a request.
• It’s Task-Oriented: It executes a single, well-defined job.
• It’s Unaware: It has no concept of the “bigger picture” or the user’s ultimate goal.

All the smart logic for coordinating these services lives elsewhere, often in a central “Orchestrator” service or hard-coded into the application’s front-end. If the payment service fails, the orchestrator must have pre-written, rigid logic to handle that specific error.

The Next: The Proactive Micro-Agent

Now, imagine that same specialist, but instead of just giving them a command, you give them a goal.

This is the micro-agent. It’s an intelligent, autonomous entity that has an objective and the power to decide how to achieve it.

• It’s Proactive: You give it a goal (e.g., “Get this order shipped”), and it decides the steps.
• It’s Goal-Oriented: It understands the “why” behind a request, not just the “what.”
• It’s Context-Aware: It can plan, execute, and even handle errors dynamically.

If the payment agent fails, the checkout agent doesn’t need to follow a rigid script. It can reason about the problem. It might decide to try an alternative payment method, or it might call the notification agent to ask the customer for a new card, all without human intervention.

The Secret Sauce: AI as the Reasoning Engine

What makes this shift possible? Artificial Intelligence (AI) and Large Language Models (LLMs).

An LLM acts as the brain or the reasoning engine for the agent. It’s what gives the agent the power to understand a complex goal, break it down into steps, and orchestrate the tools needed to get it done.

In this new model, your old microservices don’t disappear. They become the “tools” in the agent’s toolbox.

• The PaymentService (a microservice) is just a tool.
• The PaymentAgent (a micro-agent) is the intelligent “brain” that knows when and how to use that tool.

A Tale of Two Checkouts

Let’s look at a simple e-commerce example to see the difference in action.

The Future is Autonomous

Microservices were about decentralizing tasks. This was a huge step forward.

Micro-agents are about decentralizing decisions.

This is the logical and necessary next step for building systems that are not just scalable, but truly intelligent, resilient, and autonomous. The specialists in our architecture are finally getting the promotion they deserve. They transition from order-takers to problem-solvers.

A contractor supporting a critical mainframe modernization project for a state government agency, faced a significant challenge. Tasked with migrating a legacy COBOL system, the contractor’s initial pilot migration attempt using AWS Blu Age could not fully meet customer requirements. The tool could only output Java and not meet the new requirement for Python or C#. Furthermore, the migration lacked traceability, making it impossible to validate. This contractor engaged Karsun Solutions, which leveraged its AI-powered ReDuX modernization platform. Using Agentic AI capabilities powered by Amazon Bedrock, ReDuX automatically analyzed the legacy system and generated the required C# programs, Summer Batch Core workflows, and MS SQL Server tables, delivering the 100% traceability needed to successfully complete the pilot.

About the Customer

The customer was one of three vendors awarded a contract for a cloud services project for a state government agency. This project’s goal is to modernize a core business system by converting legacy mainframe code to Python or C# while moving to a cloud-based platform.

Customer Challenge

A state government agency initiated a high-priority project to convert its legacy system to a modern, cloud-based platform. The state’s primary goals were to enhance security, improve flexibility, ensure data redundancy, and lower long-term maintenance costs.

The project was structured in two phases: a competitive part one pilot awarded to three bidders, followed by a part two award for the full system conversion given to a single winner from the pilot. The customer team was tasked with migrating a subsystem for the pilot, as it was the least entangled with other subsystems.

The customer’s initial modernization attempt hit two critical roadblocks. First, the agency’s requirements evolved. After initially preferring Java, the state later specified a preference for Python or C#. This immediately put the team’s approach in jeopardy, as AWS Blu Age can only create code in Java. Second, they were unable to show file-level COBOL program traceability to modern programs. This made validation and future maintenance impossible in the mind of the customer. Failure to solve these challenges would result in a failed pilot and disqualification from the lucrative part two of the contract.

The Partner Solution

The pilot contract was explicitly for cloud services. The state agency sought the enhanced security, flexibility, and redundancy that a cloud-native solution provides. The successful solution embraced this by using a suite of AWS-native services. Additionally, Karsun used its AI-powered modernization platform, ReDuX, to solve complex traceability problems in legacy systems and could output modern C# code, directly meeting the new requirements.

The ReDuX platform rapidly analyzed the system and generated a fully modernized, traceable equivalent.

1. Agentic Analysis: First, Karsun used its ReDuX Blueprint tool. This tool, which is powered by Amazon Bedrock, applied GenAI models to analyze the system, including COBOL programs, JCL, and DB2 database tables. This process created a comprehensive and fully documented map of the legacy system’s architecture and business logic.
2. Automated Transformation: With this detailed blueprint, Karsun’s ReDuX Code Companion used agents to automatically transform the legacy application. The modernized solution consisted of:
   • Agentic Analysis: First, Karsun used its ReDuX Blueprint tool. This tool, which is powered by Amazon Bedrock, applied GenAI models to analyze the system, including all COBOL programs, JCL, and DB2 database tables. This process created a comprehensive and fully documented map of the legacy system’s architecture and business logic.
   • Automated Transformation: With this detailed blueprint, ReDuX Code Companion used agents to automatically transform the legacy application. The new, modernized solution consisted of:
     • Modern C# Application: C# programs were generated for every COBOL program. Verifiable, one-to-one mapping solved the traceability problem. This new application is hosted on .NET Core containers over the AWS EKS service or on EC2 instances.
     • Cloud-Native Batch Processing: Summer Batch Core workflows were generated for every JCL, converting all mainframe batch processes into cloud-native, serverless workflows.
     • File Storage: Application files are now stored in AWS S3.
     • Angular Front-End: A new user interface in Angular precisely mimicks the flow of the original mainframe green screens, such as the menu and work order creation screens.
     • MS SQL Server Tables: Every legacy DB2 database table was migrated to a new table in MS SQL Server.

Results and Benefits

Karsun’s AI-powered ReDuX platform successfully delivered a modernized pilot application that met all of the state’s requirements, rectifying the failures of the initial attempt. The primary benefit was the achievement of 100% traceability for the entire application stack.

The key success metric was the one-to-one mapping of legacy assets to modern, cloud-native code, all made possible by the GenAI analysis from AWS Bedrock:

• Every COBOL program was converted to a corresponding C# program, now running in .NET Core containers on AWS EKS or EC2.
• Every JCL was converted to a Summer Batch Core workflow.
• Every DB2 table was migrated to an MS SQL Server table.

This provided the customer with a complete, verifiable, and maintainable modern application, allowing them to successfully complete the pilot.

One of Karsun Solutions’ government agency customers manages critical certification systems processing millions of applications globally. This agency partnered with Karsun to modernize its legacy Software AG Natural and ADABAS mainframe system used for its certification workflows. It had demonstrated expertise in mainframe modernization and clear competency in these environments. It had also previously delivered secure, compliant cloud solutions meeting federal requirements for this customer.

It migrated the system to Amazon Web Services (AWS) using modern code deployed on Karsun’s container platform. The modernized system eliminated mainframe dependencies, reduced operational costs, enabled modern integrations, and positioned the agency for continuous innovation while maintaining seamless processing for millions of certifications.

About the Customer

The customer’s regulatory portfolio consisted of approximately 10 interconnected systems handling certifications covering both professional certifications as well as equipment registrations. While serving millions of people globally, the internal processing systems are utilized by fewer than 100 examiners, indexers, and supervisors who review and approve certification applications.

Customer Challenge

The certification system operated on legacy mainframe technology using the Software AG Natural programming language and ADABAS databases. It integrated with multiple systems including an external application submission portal, document management relying on screen scraping, and a portal where individuals manage their certifications.

Moreover, documentation of business rules was limited, making maintenance and enhancement difficult. Integration required manually keyed information from digitized documents. Additionally, recruiting developers with mainframe skills was increasingly difficult, threatening long-term system sustainability.

Partner Solution

The solution architecture utilizes Java for backend services and Angular with Angular Material for the frontend. The customer selected AWS for its proven reliability with mission-critical government systems and compliance with federal security standards. 

Tyrion Container Platform

The new system is hosted on Tyrion, Karsun’s Federal Information Security Management Act (FISMA) High-rated AWS GovCloud container platform based on Amazon EKS. The AWS GovCloud’s isolated region is specifically designed for U.S. government workloads providing the security and compliance framework necessary to meet regulatory requirements.

Karsun previously delivered Tyrion as part of a broader transformation initiative for this customer. It provides agency application owners a platform to build, test, deploy, host, and scale container-based software solutions.

The platform leverages multiple AWS services including Amazon EKS for Kubernetes orchestration, Amazon EC2 for compute resources, Amazon Elastic Block Store (EBS) for persistent storage, and Amazon RDS for managed database services. Tyrion’s DevOps ecosystem includes Tekton for build pipelines, ArgoCD implementing GitOps for continuous deployment, Karpenter for intelligent node scaling, Datadog for comprehensive monitoring, Kubecost for consumption apportionment across teams, and Backstage as a developer portal providing self-service capabilities.

System Consolidation and Modernization

Karsun consolidated two mainframe subsystems eliminating complex inter-system communication mechanisms. The team replaced legacy screen-scraping interfaces with RESTful APIs. This enabled real-time data exchange and eliminated brittle integration points.

Document Workflow Reimagined

Rather than simply replicating mainframe processes, Karsun reimagined workflows for the cloud environment. The new system retrieves only essential metadata from the document management system while maintaining secure access to document images. Karsun implemented automated processing for routine certification types eliminating unnecessary manual review and streamlining operations.

Requirements Validation Approach

Given the minimal documentation, Karsun established a rigorous requirements validation process. It worked closely with the mainframe sustainment team to analyze mainframe code and database schemas. Working with the customer, the team documented findings and confirmed functionalities. Requirements were captured as user stories with acceptance criteria following agile best practices, ensuring business approval at each increment.

Karsun introduced its ReDuX platform. This AI-powered platform for legacy code analysis accelerates discovery and delivery of complex modernization initiatives. Its parser ingests Natural mainframe code and creates comprehensive system blueprints. Using ReDuX the team validated business rules and identified edge cases often overlooked during traditional requirements gathering.

Results and Benefits

Certification processing transitioned from mainframe to AWS, delivering measurable business and technical benefits:

• Operational Efficiency: Automated processing of routine certifications eliminates manual examiner workload for specific application types, allowing staff to focus on complex cases requiring judgment.
• Technical Modernization: API-based integrations replaced screen scraping, improving reliability and reducing integration maintenance. The modern Java and Angular technology stack addresses talent acquisition challenges, with significantly larger developer pools.
• Platform Leverage: Deploying on Tyrion provides the application with enterprise-grade container orchestration, automated scaling through Karpenter, comprehensive monitoring via Datadog, and streamlined DevOps workflows through Tekton and ArgoCD. The FISMA High-rated platform eliminates the need for separate security authorization, accelerating time to production.
• Knowledge Preservation: Comprehensive documentation created during the project created a sustainable foundation for maintenance and enhancements, addressing the legacy system’s critical documentation gap.

If you followed us on LinkedIn on Halloween 2019 you may remember our Karsun “Zombie Slayers” pledged to eliminate a common legacy system scourge, dead code. Six years later our zombie code toolkit has expanded to include artificial intelligence (AI). The ReDuX AI-powered modernization platform and its Blueprint Lenses help our agile teams identify threats early and address their presence as part of the modernization process rather than risking cascading issues after deployment.

Three Zombie Code Threats

Zombie code typically refers to sections of source code in a software project that are no longer used or needed but still exist within the codebase. These unused code segments may have been part of previous versions of the software or were once essential but have become obsolete due to changes in requirements, design, or functionality. This creates system scar tissue that further complicates and constrains modernization efforts.

We identified three threats that still haunt enterprise teams today: dead weight code, living dead code, and vulnerable dead code. 

1. Dead Weight Code is not related to any application functionality. Its lack of function leads to resource drain. Remediating this non-functional code siphons away developers’ time and energy creating rework and technical debt.
2. Living Dead Code is dormant code that retains the ability to be activated. Perhaps it supports a feature no longer used by the system. However, this code poses a direct risk because it can negatively impact system output when activated by mistake. In 2019 we recounted Knight Capital’s catastrophic loss of $440 million in 30 minutes. This code woke up a dead zombie method, which incorrectly generated orders, flooding the stock market with trades.
3. Vulnerable Dead Code consists of old libraries or packages. Vulnerable dead code introduces security risks because these old components have known security issues that are easy targets.

Identifying Dead Code with AI

Over the past six years we have honed our zombie fighting skills building the ReDuX platform. Accelerating modernization with AI, the ReDuX platform begins by providing in-depth legacy system insights. This not only helps Karsun agile teams design better modern systems, it helps us identify zombie risks early so they do not impact development later. 

The first step in our process is building a Blueprint of the legacy system then diving deeper with Blueprint Lenses. Legacy subject matter experts (SMEs) upload documentation, codebases, schema and other materials into ReDuX. Using AI ReDuX agents identify the relationships between system code and components. These agents then create several views, or lenses, to understand the system better. 

For instance, a team viewing their system in ReDuX could view their API calls, scroll through requirements and compare the code citations to ensure accuracy. As part of this process they can also identify orphan code. Thus beginning the dead code analysis process.

Addressing Zombie Code Threats with System Blueprinting

Here’s how we use AI-powered Blueprint agents to address the three types of zombie code.

1. Dead Weight Code is addressed using AI to generate system requirements. By matching those requirements with specific sections of code we can also determine when code exists that does contribute to meeting these functional requirements. By only extracting functional equivalents, rather than automatic conversion, we can then abandon this type of zombie code in the legacy system graveyard. 
   
2. Living Dead Code is addressed with AI by speeding up the discovery process. Now legacy SMEs can focus on the work of understanding how every component of the legacy system interacts with internal and external components. And, by fully generating system business rules and business logic they have a clearer picture of potential unintended consequences of living dead code.
   
   Teams can then proactively determine the code and system functionality they will extract from the old system to build the new system. More importantly they can do this incrementally, preserving the old system to build new components one functional slice at a time. This provides an additional backstop against living dead code.
   
3. Vulnerable Dead Code is also targeted by extracting only the code we need. Further by focusing on functional equivalents we can modernize to optimize. Using AI code companion agents for development, we replace these libraries with modern architecture that is secure by design.

Whether moving away from risky code or outdated components, time is of the essence when trying to outrun zombie code. Providing four times faster delivery with two times less rework ReDuX is an essential tool for our zombie slayer teams. If you’re facing a similar challenge, our AI empowered teams address complex legacy challenges for government organizations and enterprise teams with complex mission-critical applications.

“Digitized isn’t modernized,” noted new Federal CIO Greg Barbaccia in a recent LinkedIn post. Here he advocates for an upgrade to the U.S. government’s approach to modernization. He argues that while agencies have replaced paper processes, they have largely replicated legacy processes in a new medium without re-engineering workflows. Thus, he calls for shifting from substitution to transformation.

Introducing the Product Mindset for Digital Transformation

That’s a process that goes beyond automating repetitive tasks. In the AI era, it means making data actionable, enabling collaboration and accelerating decision-making, changing behaviors alongside tools. That’s why Karsun uses a product mindset throughout the modernization process. Our teams consider not only project requirements but how users will interact with the modernized system. In fact, with 15+ years delivering software, cloud, and data solutions we have identified several key ways using this mindset enables digital transformation at a level expected by government decision makers.

The benefits of using a product mindset for digital transformation.

• Uses human-centered design (HCD) principles from the beginning. This ensures teams build using functional requirements that consider not only system structure, but user behavior and experience.
• Cloud native solutions, such as those built on microservices, enable secure, adaptable architecture empowering teams to adjust to changing requirements meeting future demands. 
• Applying HCD principles, a product mindset considers the experience of the teams seeking advanced analytics and business intelligence solutions to generate insights and make data driven decisions. This brings fresh data streaming and self-service enhancements, reducing the time to insights from weeks and months to hours and days.

Moreover, each of these benefits not only improves system performance, it limits future rework by addressing potential challenges early while providing the flexibility to adapt to future needs.

AI-Accelerated Digital Transformation

The AI era demands this approach. To be prepared for the agility gains from AI, government agencies and other large enterprises may need to consider using AI to accelerate the transformation to the new systems and processes available as a result of this revolutionary technology.  

We continuously enhance our ReDuX AI-powered modernization platform to accelerate this process. Unlike platforms that automate business rule extraction and transformation, ReDuX AI agents analyze system structure and behavior. After generating a comprehensive blueprint of the legacy system, we generate requirements that address user behavior. With the flexibility that comes from AI instead of automation, agile teams can reimagine their legacy system functionality, adding enhancements. Its transformation agents take inputs from human design teams and solution architects, generating modern, production ready code that satisfies these new functional requirements.

And these agents learn as they complete each functional slice of the modernized application. As the agile team engages in continuous, ongoing feedback with system stakeholders, improving both agents and human team members’ understanding of user needs improve together. Its AI-powered digital transformation that enhances rather than hinders human-centered design.

That’s not all, we found we can actually use AI for process improvement. In fact, our experts spoke on this topic at the annual CMMI conference in Phoenix, Arizona in 2024. For one customer that netted 4 times faster project delivery with double the improvement in code quality. This success is shared in a recent AWS Case Study. This data-driven approach, built on mature, intelligent AI solutions, is in part why Karsun was appraised at CMMI Level 5 (DEV) for a third time. 

At Karsun we know the power of a mindful approach to digital transformation. This product mindset, now supercharged by AI, is integrated into every aspect of our modernization process.

Experts from the Karsun ReDuX team recently joined the Fed to Fed podcast. Badri Sriraman and Judewin Gabriel joined Zack Schwartz, former CIO for the U.S. Department of Commerce, and Susan Sharer, CEO of GOVTECH CONNECTS and host of the Fed to Fed podcast. In this new episode, they discussed the use of artificial intelligence agents for rapid modernization. That includes legacy system challenges, overhyped AI, and crafting effective solutions given operational challenges.

An Urgent Need for Rapid Modernization

As they observe, the need for modernization is pervasive across government agencies. Driven by an expectation for faster, more robust, and bigger and better capabilities, today’s agencies demand speed and efficiency. Meanwhile, public expectations, shaped by advancements seen in the news, push government organizations further.

At the same time, federal leaders must balance the rise of overhyped AI solutions. These may not be fully vetted, lack support and fall flat in production environments. How then can systems integrators build trust while providing the rapid modernization solutions government agencies need?

ReDuX: The AI-First Modernization Platform Answer

To meet this demand for efficiency, agility, and accuracy, Karsun Solutions developed ReDuX, an AI-first platform that rethinks how modernization happens. It brings rapid modernization to legacy systems that have evolved over decades and often lack institutional knowledge. Even though this complexity increases risk, ReDuX moves beyond manual assessments to provide transparency and generate high quality, production ready code that requires less rework, speeding time to delivery.

How ReDuX Enables Rapid Modernization

• Multimodal AI agents build knowledge graphs from various inputs, including source code, documentation, schema information, and system demonstrations.
• Agents extract logic (APIs, batch jobs, user flows, calculations) and convert it into human-readable summaries, backed by citations.
• Agile teams review and assess legacy domains, then uncover user behaviors, business rules, data flows, and system architecture.
• Agents and teams translate business requirements into Given-When-Then (GWTs) for behavior-driven development (BDD). 
• Teams reimagine the modernized systems, generating new software capabilities while preserving required functionality and supporting automated testing, ensuring functional equivalence between old and new systems.
• Teams then mobilize agents that take this information and other inputs as they generate purpose-fit, production-ready code.

The result, two times reduced effort, two times improved quality, and four times reduced time to implementation. Moreover, ReDuX takes several steps to improve the trustworthiness of the outputs produced by its AI agents. That includes using human-in-the-loop to validate outputs, automated reprocessing, implementing formal methods that specify software behavior, and active learning. If mistakes slip through, the system enables teams to trigger automated reprocessing based on feedback, making the blueprint agents smarter and more reliable over time.

The Next Evolution: Autonomous AI Agents

Karsun Solutions has a 15-year history of large-scale modernization work for federal agencies, and Redux emerged from this experience. Now the ReDuX team is applying that experience by evolving their platform to use the latest technological development. Autonomous AI agents link together forming a digital workforce capable of handling everything from product user stories to technical and production tickets. These agents learn from feedback, adapt to priorities, and collaborate like a real team. This enables precise, focused micro tools and facilitates moldable development.

Whether cultivating stakeholder relationships effectively, going the extra mile while gathering detailed business requirements for a complex project, or leading technical transition teams, working with experts opens the door to new process efficiencies and cost savings. That expertise includes not only technical expertise, but a deep understanding of the importance of mission-critical systems to government agencies and their constituents. From start to finish, Karsun team members are trusted by public sector agencies for their expertise. 

Customer Success with Karsun Cloud Experts

No where is this clearer than during our recent quarterly employee awards celebration. At that event, one Karsun team member was recognized for her work securing savings for one of our agency customers. As part of our engagement, she performed detailed analyses of 72 AWS accounts. In doing so, she identified a significant potential annual cost reduction by introducing targeted efficiency improvements and infrastructure optimizations. That includes server rightsizing, identifying idle resources, and utilizing AWS Savings Plan and Instance Scheduling. As a result, the team successfully recovered 25% in annual savings for their customer!

Partnering with Cloud Experts

This is one of many examples of our efficiency-driving approach to enterprise modernization. Karsun is an AWS Advanced Services Partner with Migration and Modernization, DevOps, and Government Competencies. To earn each of these designations, Karsun teams delivered multiple customer engagements in each category using industry best practices. These approaches create both cost savings and process efficiencies. Its software development methodology has been assessed at CMMI Level 5 multiple times. This is the highest level maturity appraisal and indicates Karsun’s commitment to using a data driven approach to improving its software practice.

Selecting a Cloud Partner

There are numerous benefits to working with cloud experts experienced in delivering modernization solutions for mission-critical systems. These are some of the best reasons to choose a partner with proven performance and expertise:

1. For complex engagements, connect with partners that have demonstrated technical proficiency and success in specific domains such as: AI/ML, Migration and Modernization, DevOps/DevSecOps, Data Modernization, DataOps, and Government. If they hold a certification like an AWS competency, they have passed a rigorous audit of their architecture, customer references, and staff certifications.
2. Certified partners bring faster time to value. In order to complete industry certifications and appraisals, systems integrators (SIs) must bring repeatable frameworks, accelerators, and automation that reduce risk and speed up delivery. For instance, Karsun’s in-house Innovation Center has teams dedicated to this goal via its Modernization Toolkits. This is especially valuable for cloud migrations (Cloud Runways) and application modernization (accelerated via the ReDuX AI-powered modernization platform and GoLean agile platform.)
3. SIs with strong technical partnerships provide alignment and co-sell support.These partners often work closely with their respective account teams. That also means they may have additional access to incentives and accelerators. For instance, Karsun’s AWS Migration and Modernization Competency provides access to Migration Acceleration Program (MAP) resources.

Public sector and mission driven leaders should choose a partner with strong expertise when modernizing a mission-critical or regulated workload or modernizing complex legacy systems (e.g., COBOL to microservices). Doing so ensures they will bring best practices, support organizations navigating funding programs or go-to-market support, and engage experts to find cost-savings and efficiency gains. Connect with our experts to learn more.

As we enter the fourth quarter of a turbulent federal technology market, our Karsun experts are adapting to meet the evolving needs and missions of our agency customers. At the same time, meeting the demand for artificial intelligence enabled tools, our Karsun Innovation Center developed ReDuX, a comprehensive, end-to-end AI-accelerated modernization platform for the entire software development lifecycle. Today, as we close out the first half of 2025, we summarize some of the insights shared by experts in our Innovation Center and from our teams serving our U.S. government partners. 

Bringing Thought Leadership to the IT Industry

Karsun thought leaders joined the AWS Mainframe Modernization Forum, the Federal Tech Podcast and other forums to share their experience with our ReDuX platform. In short, they observed, government modernization faces significant challenges from shrinking workforces and reliance on decades-old, mission-critical legacy systems which are difficult to maintain and often lack up-to-date subject matter expertise as veteran employees retire. This directly impacts federal customer experience, with only 23% of Americans finding federal services easy to navigate. 

At these events, these Karsun experts revealed their ReDuX AI-powered modernization platform offers a crucial solution by deploying a digital workforce of AI agents. These agents effectively become Subject Matter Experts (SMEs) for legacy systems, blueprinting their architecture and converting intricate code to modern cloud platforms. This approach dramatically benefits development teams by accelerating complex migrations, enhancing code quality, and reducing costs, allowing human teams to focus on strategic, high-value work. 

Ultimately, ReDuX aims to make federal services more usable, faster, and lead to more satisfied customers.

New Insights at Innovation Town Halls

In addition to our thought expertise at industry events, our experts currently working on real-world modernization engagements shared their experience at monthly Innovation Town Halls. We shared some of the insights from these experts on LinkedIn and in recent blogs. 

That includes describing how Karsun innovates quickly while ensuring high-quality delivery. For instance, we shared how Karsun uses artificial intelligence to drive process improvement and ensure data privacy. ReDuX AI is central to this, enhancing productivity by 22.5% for mainframe modernization. For instance, ReDuX addresses code parsing challenges early then generates production-ready code faster than human teams. Karsun’s approach also integrates AI for human-centered design (HCD) and can enhance organizations’ Zero Trust Architecture posture. This comprehensive approach is underpinned by an innovation culture prioritizing cross-functional collaboration and strategic investment in the right technology and processes.
