What I'm looking for

I’m looking for a role where I build secure, scalable Java backend services with Spring Boot and REST APIs, collaborate through code reviews, and continuously improve performance, reliability, and maintainability.

I’m a Java Backend Developer with 9 months of professional experience building scalable backend applications using Java, Spring Boot, Spring Security, Hibernate/JPA, PostgreSQL, and REST APIs. I focus on secure authentication, clean architecture, and reliable service design that’s maintainable over time.

In my recent role, I developed and maintained secure RESTful APIs with JWT and role-based access control, and I improved performance through query optimization, debugging, logging, exception handling, and unit/integration testing. I also collaborate through Git/GitHub code reviews and help resolve production issues, and I enjoy turning features into well-structured, testable backend solutions—like my Job Portal and real-time Chat Verse projects.
