I’m Faisal. Most people find me online as FaisalKhanDev. I’m a full-stack AI developer with 6+ years of experience, and over the last few years my work has shifted heavily toward AI: building systems that don’t just serve data, but actually reason over it, automate around it, or act on it. On the frontend, I mostly work in React and Next.js. On the backend, Node.js, NestJS, and PostgreSQL. For AI work, that’s Python, Hugging Face, LangChain, the OpenAI API, and increasingly agentic systems and tools that can take multi-step actions on their own rather than just returning a single response.
