AI Engineer  /  Full-Stack Developer

I build AI products end-to-end — from LLM pipelines, RAG and agents to the backend, data layer, and UI that ship them. One engineer, full cycle.

About

I'm a full-stack engineer who specializes in turning AI capabilities into real, working products — systems people actually use, not prototypes that demo well and break in production.

My daily work blends LLM integration (OpenAI, Gemini, Claude), RAG pipelines, embeddings and automation with a solid full-stack foundation: TypeScript, Next.js, Node.js, PostgreSQL. I've led a CRM team, built realtime systems with WebSockets, and turned plenty of unreliable third-party data into something dependable.

What I'm good at is the full cycle — architecture, the AI layer, the backend, the database, the interface, the deploy. The breadth that lets one engineer own a product from idea to result.
