Muhammad Hassan

Senior React and React Native engineer. Five years of full-cycle delivery — architecture to App Store submission, mostly as the sole or lead engineer. I take hard, under-documented problems and ship them. Astra Chat: Matrix-protocol messaging app, full E2E encryption, no official React Native SDK, delivered in four weeks. MatesLive: five payment gateways unified into one web layer for a platform with over one million users. Nemrah Ahmad: a custom Lexical editor on the web with a matching renderer in React Native, no reference implementation to follow. Now actively expanding into AI automation. I've been building hands-on with n8n, CrewAI, and the OpenAI and Claude APIs. No shipped client AI projects yet — but five years of knowing what breaks at the edges transfers directly into building agent workflows that hold up in production. Open to senior engineering roles and client projects across E-commerce, EdTech, and Social Tech.
