Geoffrey

Software Developer - Chennai, India

I build complete products end to end.

Web interfaces in Next.js and React, mobile apps in React Native and native Swift, and the Express, PostgreSQL, Redis, and AWS layers that keep them running. Lately I've been going deep on Swift and SwiftUI by building an iOS app from the ground up.
