01 — About

Turning language models into real products

I'm a Generative AI Engineer with hands-on experience building LLM-powered applications and RAG systems. I work with the OpenAI & Claude APIs, LangChain, and vector databases to create intelligent chatbots and document-processing solutions — and I'm comfortable shipping them to AWS and GCP.
