About Me

Passionate AI Engineer & Full-Stack Developer

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

I care about AI that is observable, dependable, and useful to the people using it—not demos for demos' sake.

AI & Machine Learning

Intelligent systems, LLM apps, and RAG pipelines tuned for production—not slide decks.

Full-Stack Development

Scalable web apps with React, Node.js, Python, and FastAPI—from API design to UI polish.

Innovation Driven

Shipping pragmatic solutions with new tools when they earn their place in the stack.

Always Learning

Hands-on experimentation with the parts of the stack that matter most for production AI.

  • RAG architecture, retrieval quality, and evaluation
  • Multi-agent workflows with LangGraph
  • LLM fine-tuning (LoRA / QLoRA) for domain-specific tasks
  • Vector and hybrid search (Pinecone, Weaviate, Chroma)
  • Observability with LangSmith and LangFuse

Specialized in building production-ready AI systems, RAG pipelines, and scalable web applications using cutting-edge technologies.
