I'm Abdul Rafay, a software engineer based in Lahore, Pakistan. I build AI/ML systems and full-stack products - voice assistants, RAG pipelines, and web apps - bridging complex models with what teams actually ship.

Over 7+ years I've worked on AI customer support, collaboration platforms, and data-heavy backends, with a focus on reliability, clear interfaces, and measurable outcomes.
