Work History

Software Developer

TCS
11.2022 - 08.2026
  • Designed and developed scalable backend services using Java 17 and Spring Boot, applying records, sealed classes, and switch expressions to cut boilerplate and improve code readability.
  • Built data access layers using Spring Data JPA and MySQL, writing optimized queries, indexes, and pagination that reduced average query response time by ~30%.
  • Implemented secure authentication and authorization using Spring Security with JWT and role-based access control, protecting REST endpoints across multiple services.
  • Developed RESTful APIs with Spring Boot and REST best practices (versioning, validation, global exception handling) consumed by web and mobile clients.
  • Implemented GraphQL APIs alongside REST to let clients fetch exactly the data they need, reducing over-fetching and payload size on data-heavy screens.
  • Architected and migrated a monolithic application to microservices using Spring Boot and Spring Cloud, improving deployment independence and fault isolation.
  • Configured Spring Cloud API Gateway as the single entry point for routing, authentication, rate limiting, and request logging across services.
  • Implemented Service Discovery with Eureka and Spring Cloud Load Balancer to enable dynamic service registration and client-side load balancing, removing hard-coded service URLs and improving availability.
  • Containerized microservices with Docker and deployed them on AWS (EC2/ECS, RDS for MySQL), ensuring consistent environments from development to production.
  • Managed builds and dependencies with Maven, and integrated it into CI/CD pipelines for automated build, test, and deployment.
  • Integrated SonarQube with Maven in the CI pipeline to enforce quality gates, reducing code smells and bugs and raising test coverage to 80%+.
