I'm Hamza — a full stack developer who specialises in AI. For more than four years I've been turning ideas into intelligent products: voice agents that pick up real phone calls, multi-tenant platforms that clinics and field-service teams run on daily, and retrieval systems that make documents genuinely useful.
I like owning the whole lifecycle — the interface, the API, the model integration and the deployment — because that's where a product actually comes together. Every project here was built to serve real users, not to sit in a demo.
