What I'm looking for

I'm looking to build scalable, reliable, high-performance web services and distributed systems, contribute to strong engineering teams, and keep growing through challenging backend, cloud, and AI-focused work.

I've built backend REST and GraphQL APIs, business logic, and caching systems at Swapheart using Java, Spring Boot, Node.js, PostgreSQL, and Redis, reducing p99 response latency by 40%.

At FOSSEE, IIT Bombay, I debugged dependency and networking issues in eSim 2.5 on Ubuntu and contributed 8 merged PRs to its C++/Python open-source repository, including automated test coverage and critical installation fixes.

I also build large-scale systems such as DivineShield AI, a seven-microservice platform designed for 50,000+ concurrent users, and BharatFlow AI, a real-time fraud-detection pipeline processing 1B+ events daily. Competitive programming has strengthened my algorithmic problem-solving, including Global Rank 1 in CodeChef Starters 141 and strong ICPC regional results.
