About me

My story in a nutshell

I'm a software engineer at a US-based startup - Nuaav. On the side, I freelance — picking up small projects where I can genuinely help.

I started building in college — Travellio and Collabaid taught me a lot (including a healthy respect for my own limits). These days I focus on systems automation, data pipelines and semantic search at work, while building things on the side.

This site is a resume & portfolio in one — a software engineer by day, with small, focused projects on the side.

Honest scoping — I'd rather be upfront about what fits than over-promise.

Simple over clever — reliable, maintainable work that holds up in production.
