What I'm looking for

I’m looking for a backend/API role where I can build secure REST services in Java/Spring Boot, work with PostgreSQL/MySQL, and ship containerized applications using Docker.

I’m a B.Tech Computer Science student specializing in backend and API development using Java and Spring Boot. I focus on building secure REST APIs, including JWT authentication and role-based access control (RBAC) with Spring Security.

In my projects, I’ve created multi-layered Controller/Service/Repository architectures, built task workflows with PostgreSQL and JPA, and Dockerized applications for reliable deployment. I also wrote 150+ unit and integration tests to validate end-to-end request behavior.
