About Me

Building AI That
Actually Works

I'm an AI Engineer and Full-Stack Developer based in Lahore, Pakistan, working with clients across the US, UK, and Europe. I don't build demos — I ship production systems that run 24/7 and deliver measurable results.

My background in Laravel, Vue.js, and Node.js means I can own the entire product — from the AI layer down to the infrastructure. No handoffs, no gaps, no excuses.

In the last 2 years I've gone deep on RAG pipelines, Voice AI, multi-agent systems, and workflow automation — the four areas where AI is genuinely transforming how businesses operate right now.
