I'm building production-style Java backend systems with Spring Boot, Spring Data JPA, MySQL, JWT authentication, and JUnit/Mockito testing.

As an open-source contributor to INCF / The Virtual Brain, I've submitted five pull requests across three repositories. My work includes a seven-component parameter-space exploration library with 35 passing pytest cases, a non-interactive environment bug fix, documentation improvements, 127 new unit tests for signal-processing utilities, and FastAPI rate-limiting middleware for an LLM chat endpoint.

I built a Library Management System with 15+ REST endpoints, role-based JWT authorization, BCrypt password hashing, and a normalized MySQL schema. I also built a Task Management API for task creation, assignment, and status tracking using a test-driven workflow.

I'm a Google Student Ambassador for Team Gemini and am completing my B.Tech in Computer Science Engineering. I bring strong DSA fundamentals, hands-on backend engineering, and experience collaborating through GitHub pull-request workflows.
