Curiosity, backed
by execution.

I enjoy understanding why a system behaves the way it does—not just making the happy path work.

SK.

Hello, I'm Sumit.

A Computer Science undergraduate at Vishwakarma Institute of Technology, Pune, with hands-on software development experience and a strong interest in backend architecture.

My work spans Java/Spring Boot services, reliable concurrent systems, event streaming, observability, and emerging AI engineering workflows. I enjoy taking ideas from first principles to working implementations.
