Message

At FiveLoop Technology, I lead AI engineering initiatives, building RAG pipelines, document intelligence workflows, and conversational AI features with OpenAI, Claude, Qwen, and LangChain.

I design scalable applications and backend services, and architect knowledge-retrieval systems using OCR, embeddings, and vector search. I also own CI/CD pipelines and AWS infrastructure supporting production AI applications.

At GameNock, I led full-stack development and introduced the company's first AI-powered capabilities, including early RAG and LangChain workflows for conversational and knowledge-retrieval features.

My projects include Lumn Bio, GovDoc AI, an AI receptionist for dental practices, and Portion Track. Across them, I've worked on healthcare document extraction, government-record search, voice AI, and photo-based food recognition.
