Our Karsun corporate interns .. Today we feature the experience of one of our 2026 interns, Neha Chaudhary. In the following blog she shares her internship experience working with Karsun’s Growth, Business Development and Marketing teams.

A New Beginning

Transitioning from the military to the corporate world was both an exciting and challenging step for me. Karsun is the first company I’ve had the opportunity to work with in this new phase of my journey, and it has played a pivotal role in shaping my understanding of how organizations operate beyond structured environments.

A Culture That Supports Growth

From day one, what stood out to me was Karsun’s open and supportive culture. I was encouraged to ask questions, explore new tools, and take ownership of my work. This environment not only made my transition smoother but also gave me the confidence to step outside my comfort zone and contribute meaningfully. The constant support from my team ensured that learning was continuous and practical.

My Role and Responsibilities

As a Management Analyst Intern, I worked closely with the Business Development (Growth & Development) and Marketing teams. My role went beyond observation; I was actively involved in tasks that contributed to real business outcomes. This hands-on experience helped me understand how strategy and execution align in a corporate setting.

Learning Industry Tools

A key highlight of my internship was gaining hands-on experience with essential industry tools. I worked with Jira to track tasks and understand workflow management, which gave me insight into how teams stay aligned and efficient. Using SharePoint, I learned how organizations manage documentation and collaborate seamlessly across teams. Additionally, Excel became an important tool for organizing data, building structured lists, and supporting decision-making processes.

Key Projects and Contributions

During my internship, I had the opportunity to contribute to several impactful initiatives. I worked on building battlecards for state and local profiles, which supported business development efforts by providing structured insights and strategic positioning. I was also involved in coordinating logistics for the upcoming AWS DC Summit, where I assisted in finalizing the venue and managing other key arrangements; an experience that gave me a strong sense of ownership and accountability.

In addition, I created bulk target account lists using Excel to support outreach efforts, ensuring a more focused and efficient approach. One of the most meaningful tasks for me was developing empathy maps for key profiles, particularly for potential connections within the U.S. Department of War. This allowed me to connect my background with my work, helping the team better understand and engage with prospective clients.

Skills and Takeaways

Through these experiences, I developed strong skills in analytical thinking, project coordination, and cross-functional collaboration. I learned how to manage tasks efficiently, work with data in a structured way, and communicate effectively across teams. More importantly, I gained the ability to connect insights with action, an essential skill in any business environment.

Looking Ahead

This internship has been more than just a learning experience, it has been a significant transition point in my career. Karsun provided me with the right environment, tools, and mentorship to grow, adapt, and build confidence in a completely new domain.

As I move forward, I carry with me not only the skills I’ve developed but also a mindset of continuous learning and adaptability. This experience has laid a strong foundation for my journey ahead, and I am truly grateful to have started it with Karsun.

What is your favorite part about working with the Karsun Innovation Center?

My favorite part about working at Karsun Innovation Center has been the culture of collaboration and continuous learning. I truly appreciated how supportive and approachable everyone was. I was encouraged to ask questions, explore new tools, and contribute to meaningful projects from the very beginning. The environment made me feel valued not just as an intern, but as a team member whose work had real impact.

What is your biggest takeaway from your experience as an intern at Karsun?

My biggest takeaway from this internship has been learning how strategy, collaboration, and technology come together to drive business outcomes. Through working with the Business Development and Marketing teams, I gained hands-on experience with tools like Jira, SharePoint, and Excel while contributing to projects such as building battlecards, coordinating logistics for the AWS DC Summit, and developing targeted outreach strategies. More importantly, I learned the importance of adaptability, communication, and taking initiative in a fast-paced professional environment.

What do you want to do after this internship? What are your career goals?

After this internship, I want to continue building my career in business strategy, operations, and project coordination while expanding my knowledge of technology-driven solutions. My goal is to grow into a role where I can combine analytical thinking, leadership, and collaboration to support organizational growth and meaningful impact. Coming from a military background, I value discipline, teamwork, and mission-focused execution, and I hope to continue applying those strengths as I advance in my professional journey.

When teams move from deciding on their migration strategy to mobilizing to act, agentic AI can be used to enforce secure-by-design practices and policies. Welcome back to the second in our two part series on using agentic AI for DevSecOps to drive secure-by-design architecture. (If you missed part one, check out our previous post The Speed of Relevance: Laying the Foundation for Strong DevSecOps Practices)

Infrastructure as Code Delivers Automated Compliance Enforcement

Secure-by-design principles are enabled through both infrastructure as code and robust security testing practices. First, deployments via infrastructure-as-code (IaC) produce consistent, repeatable, and hardened environments, reducing misconfigurations. This addresses a common security weakness. Additionally, these pipelines generate detailed logs and audit trails.

Furthermore, pipelines can embed policy-as-code and compliance-as-code frameworks, continuously validating that builds align with standards like NIST, CMMC, STIG, RMF, or agency-specific security baselines. They can also build custom workflows and templates that ensure their DevSecOps agents work consistently following their internal guidelines and processes.

There are many examples of how teams can use preconfigured DevSecOps templates and workflows to enhance their security:

• Pipeline templates that enforce secure configurations by default (e.g., encryption turned on, least privilege IAM roles, logging enabled) across every environment.
• Workflows that eliminate hardcoded credentials by integrating with vaults and key management services, ensuring sensitive data is injected securely at runtime.
• Automated pipelines that support rolling updates and security patching, making it easier to quickly remediate vulnerabilities without manual intervention.

Automated Security Testing Provides Guardrails

The other component is security testing. Using ReDuX AI agents in combination with other automation tools, DevSecOps teams use security testing (static code analysis, dependency scanning, secret detection) early in the pipeline, ensuring vulnerabilities are caught before deployment.

Moreover, for every task performed by any ReDuX agent, output can be verified and corrected by a human team member. The self-learning agents improve their process, further improving efficiency gains. And because in enterprise implementations of ReDuX agents share skill improvements across the digital workforce, all agents improve when one agent improves. This process further enhances security beyond what is available with simply co-pilot tools or AI agents used for a single step of the process.

Ultimately, by both using OODA loops as described in our first post and automated compliance, teams can use AI for end enforcement of DevSecOps best practices. In addition to this, one of the most important ways DevSecOps supports security best practices is it fosters a culture of continuous improvement and collaboration, particularly between developers, security, and operations. At its core, DevSecOps best practices shift important security decisions to the left, moving them earlier in the process so that the tools use by modernization teams have the greatest impact at reducing risk.
If you want to see how your team can accelerate decision making and modernize with secure-by-design architecture, schedule a live demonstration with our team. And if you are headed to the AFCEA Belvoir Industry Days May 5-7, 2026, Let’s talk!

Last year our team examined agentic DevSecOps for secure-by-design architecture on our ReDuX blog. In this two part series, experts in our Defense portfolio are returning to their call to shift security decision making left. With renewed attention to the needs of the warfighter and the mission we address these new challenges and opportunities.

For agencies operating in an IL4 or IL5 environment integrating security into their modernization is an essential requirement of the mission. Modern environments must adhere to strict security standards, meet data sovereignty requirements, and enforce secure CI/CD pipelines all while operating within GovCloud.

In short, to effectively optimize DevOps outputs using AI, agencies must partner with organizations that have proven experience working with their highly-regulated environments. Moreover, when the modernized systems are well-architected, they directly operationalize secure-by-design principles. To achieve this state we use our ReDuX platform to observe to understand the legacy system, make informed decisions early and when relevant while building incrementally to adapt to changing mandates.

Shift-Left Security and the Speed of Relevance

In our original post, we noted, the earlier teams identify problems and security risks, the earlier they adapt and develop solutions. We call this Shift-Left Security and it greatly improves the speed of relevance for making critical architecture decisions that improve the overall security of the system.

Shift-Left Security is based on our integration of the Observe-Orient-Decide-Act (OODA) loop into our GoLean development methodology. With GoLean we observe process improvement opportunities earlier. After orienting to a new approach, we then decide on process improvements and act to implement it within our work. As a result of using this data-driven OODA loop process for over a decade our development methodology has been repeatedly appraised at CMMI Level 5. 

When incorporated into our ReDuX process we use OODA loops to not only continuously improve process but also to reduce risk. We do this by building a comprehensive blueprint of the legacy system so we can observe risks. Next we orient to plan our migration roadmap, then decide to mobilize agents and teams to complete our work and finally, act to incrementally modernize while reducing rework.

Reducing Risk with Legacy System Blueprinting

Using agentic AI in our ReDuX platform, blueprinting agents map the structure of legacy systems and identifies its relationship to external components. Our teams can then match legacy code to screen flows and end-points so that teams identify orphan or dead code before they begin migration planning.

Thus, using agentic-driven blueprinting we greatly accelerate the speed of relevance for making critical security decisions. We move the decisions about how to improve, optimize and reimagine the system earlier in the discovery phase which allows us to act and adapt sooner to emerging risks.

If you want to learn how we use system blueprinting to accelerate decisionmaking and build secure systems, schedule a live demo with our team. If you are headed to the AFCEA Belvoir Industry Days May 5-7, 2026, Let’s talk!

And stay tuned! In our next blog we will share how we use AI agents to build secure architecture as part of our DevSecOps practice.

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.
