Hammad Mustafa — Full Stack Developer & Agentic AI Engineer

Full Stack Engineer specialising in the MERN stack, Next.js and AI integration. I build production-grade web applications powered by Retrieval-Augmented Generation, vector search and agentic AI systems.

About Hammad Mustafa

I am a forward-thinking Full Stack Engineer based in Karachi, Pakistan, with a strong foundation in building production-grade web applications. My core expertise is the MERN stack — MongoDB, Express.js, React.js and Node.js — with a specialised focus on Next.js and AI integration covering RAG, vector search and agentic AI. I have a proven track record of delivering scalable backend logic, responsive frontend interfaces and Python-based microservices that hold up under real traffic.

Day to day I design REST APIs, model MongoDB and PostgreSQL schemas, wire up secure authentication with JWT and Clerk, and ship accessible, mobile-first interfaces with React, Next.js and Tailwind CSS. On the AI side I build retrieval pipelines over vector databases, engineer prompts for large language models, and connect them to real product workflows rather than demos. I am currently focused on intelligent education systems and scalable web applications built on modern AI tooling.
