Ubaid Desai, full-stack developer.

I build full production software end to end, not just marketing sites — medical apps, browser games with simulation engines built from scratch, and websites for local businesses through the agency I founded and run.

A bit about me

I'm based in Durban, South Africa, and I like building things that actually get used — not just demos. That's meant medical apps, browser games, and websites for local businesses, usually all in the same month.

Outside of client work, I run Qroma, my own digital agency, freelance as a web developer and QA specialist, and spend time training and evaluating AI models. I'm also currently studying Computer Science and working toward a Higher Certificate in Mobile and Web Development at Emeris — still learning while I ship.
