About Me

I'm a mobile and frontend developer with a decade of experience shipping React, React Native, and Next.js products — from fintech and digital signature apps to AI-powered mobile tools and production admin dashboards.

Currently freelancing, I'm the sole frontend developer on Report Plus, a building-supervision admin platform. Previously at Hashthink, Shakeylead, and Hamyar Koosha. I also teach Git & GitHub and contributed to React documentation.
