About

Background

I am a full-stack developer. I work mostly in Node, React and Postgres, and I take projects from the database schema through the API to the interface.

Most of my experience is agency work: usually three client projects running at once, plus two junior developers to mentor. That work has covered e-commerce, real estate and IoT.

Outside that I built an e-commerce platform for my dad's grocery shop, covering products, orders, delivery rules, UPI payments and an admin panel he runs himself. I also built CallShot, a cricket prediction game for a friend group.
