Abdullah Hafeez
I'm a Tech Lead and Full Stack Mobile Engineer with 9+ years building and scaling production software across mobile and web. I work daily in React Native, Flutter, native Android and iOS, Node.js, and TypeScript, and I ship AI and LLM-powered features into live products: in-app chat and assistants, recommendation systems, and RAG over your own data. I build apps from scratch, rescue stalled ones, and get them onto the App Store and Google Play.
