About

I'm a full-stack developer and AI/ML engineer based in Pakistan with 5+ years of experience shipping production software. I work across the entire stack — from building AI agents and RAG systems to developing Laravel backends, React frontends, and custom WordPress solutions.

I've built 15+ WordPress plugins, multiple AI-powered SaaS products, and end-to-end ML pipelines deployed on GPU infrastructure. I help startups and businesses turn ideas into scalable, production-ready applications.
