Building scalable web applications, AI-powered products, and modern backend systems.
I'm Nouman A Khan, a Full Stack AI Engineer with experience building production applications across the MERN and PERN stacks, with a growing focus on Python backend engineering and AI/LLM systems.
My engineering journey combines full-stack development with modern AI engineering, allowing me to build applications that are not only scalable and maintainable, but also capable of leveraging LLMs, RAG pipelines, vector search, and agentic workflows to solve real-world problems.
I enjoy working across the stack — from building modern interfaces with React, Next.js, and TypeScript, to designing scalable APIs and backend systems with Node.js, Express, Python, and FastAPI, and integrating intelligent AI capabilities into production applications.
