Who I Am

Backend engineer
with a builder's mindset

I'm a Java Backend Developer based in Vadodara, India — currently pursuing my MCA at Manipal University while building real-world production-grade systems on the side.

My focus is clean, maintainable architecture: designing REST APIs, implementing JWT-based auth, optimising PostgreSQL queries, and scaling with Redis caching.

I believe in shipping things that actually work in production — not just tutorials. Both of my featured projects are full-stack backend systems built to handle real traffic patterns.
