Full Stack Developer

Software engineer at Mphasis. I write Rust when latency matters, TypeScript when speed of shipping does.

Prev: shipped dashboards to 500+ daily users at Henceforth Solutions. Now building things that don't fall over - pipelines, open-source tooling, and whatever Solana problem is in front of me.
