About

[01]

I architect distributed systems and build production-grade microservices that scale — with a strong eye for clean APIs, observability, and developer experience.

Currently a final-year B.Tech IT student at SGGS Nanded, sharpening my craft in Java, Spring Boot, and event-driven architectures while solving hard problems competitively on LeetCode, Codeforces, and CodeChef.
