About Me

Building real
products, not just code

I turn complex business requirements into fast, maintainable systems that hold up in production.

I'm a Senior Full-Stack Developer and Team Lead based in Lahore, Pakistan with 7+ years of experience shipping production-grade web applications across healthcare, real estate, ed-tech, and marketing verticals.

My current focus at SLTech is building AI-powered systems — including a production RAG chatbot using OpenAI embeddings and Chroma Cloud, agentic workflows, and a custom Coolify OAuth shim for prompt-driven deployments via Claude MCP.

I've led teams of 6+, delivered platforms serving 200,000+ users, and won multiple Employee of the Month awards. I believe in clean architecture, real performance gains, and software that ships.
