I build the stuff that keeps the lights on.

Go & Node.js backends, real-time APIs, Web3 infrastructure —
shipped in production, not just on localhost.

About Me

I'm a backend-first developer studying IT in Mumbai.

My zone is APIs that don't crumble under load, real-time pipelines in Go & WebSockets, and fullstack apps where the backend does the heavy lifting.

Shipped a Web3 task platform on Solana, a live stock streaming app in Go, and production recruitment systems that replaced Google Forms for an entire college.

Currently looking for backend / fullstack roles — remote or Mumbai.
