I turn hard problems into shipped products.Full-stack engineering, with AI agents & RAG built in.

I start with your problem, not a tech stack. Senior full-stack engineer with 10 years shipping production systems for healthtech and fintech teams — I own architecture end-to-end (Node/NestJS + React/Angular) and wire agentic AI and RAG into real products, not demos.

A senior engineer who owns the whole stack.

Majid Sohail Khan

I'm a senior software engineer who thrives across the entire development lifecycle — from architecture and API design through to polished, production interfaces. Over ten years I've shipped and maintained systems in regulated, high-stakes domains like healthtech and fintech.

My edge is bringing AI into products that already exist: designing agents, agentic workflows, and RAG that fit an existing data model and auth so they ship as real, trustworthy features — not demos. I care about clean, structured code that other engineers can adopt and extend.
