What I'm looking for

I seek roles building scalable Spring Boot microservices and secure APIs in Agile teams, with opportunities for hands-on backend design, performance tuning, and CI/CD-driven delivery.

I am a Java developer specializing in building scalable enterprise applications using Java, Spring Boot, and microservices architectures. I design and secure RESTful APIs, implement Spring Security with JWT and LDAP, and integrate systems with external services.

At Wipro I developed backend modules for insurance operations, created microservices for policy management, and optimized SQL queries and caching strategies to improve performance. I automated health checks and CI/CD pipelines to increase deployment reliability.

On projects for clients such as a life insurer and Mahindra & Mahindra, I contributed as a full-stack developer, improving response times through Ajax optimizations, designing database schemas, and implementing role-based access controls and document-processing features.

I follow Agile/Scrum practices, write unit and integration tests with JUnit and Mockito to maintain high code coverage, and use Docker, Jenkins, Git, and monitoring tools to deliver robust production-ready solutions.
