Experience

Healthcare Insurance Portal

Worked on a healthcare insurance domain project involving the migration of a legacy monolithic application to a modern microservices-based architecture using Java 17, Spring Boot 3, and functional programming principles. The primary goal was to enhance scalability, maintainability, and deployment flexibility while reducing technical debt. I played a key role in designing the microservices architecture, defining API contracts, implementing services, and promoting clean, modular code.

I actively applied functional programming patterns using Java 17 features such as records, sealed classes, streams, and optionals to reduce side effects and improve code readability. I ensured clean code practices across the codebase, introduced reusable utility components, and enforced SOLID principles through peer reviews and mentorship.

In addition to development, I contributed to the architecture design, service decomposition strategy, and standardization of error handling, logging, and security layers. I collaborated with DevOps for CI/CD integration and containerized deployments, aligning with modern cloud-native standards. My efforts improved developer velocity, better system performance, and easier onboarding for new team members.
