Who I Am

I'm a Java Spring Boot Full Stack Developer and B.Tech student in Information Technology at ACE Engineering College, Hyderabad. I specialize in building real-time systems using Spring Boot, React, WebSockets, and Docker.

I've built competitive coding platforms, trip planning systems, and skill exchange apps — all deployed to production. I thrive on designing scalable REST APIs, implementing microservices, and optimizing database performance.

Beyond development, I'm a LeetCode Knight (Rating: 1924, top 4% globally) with 700+ DSA problems solved. I also founded a peer-learning group of 30+ participants focused on DSA, Flutter, and backend development.
