About
I’m Jonas Vanbuel, a full-stack AI engineer based in Antwerp, specialising in custom RAG systems and LLM-powered interfaces grounded in your data — not the open web. You bring the domain expertise; I build the infrastructure that makes your knowledge base queryable and actionable. The result: untapped data turned into clear, decisive intelligence.
As a founder-engineer, I shipped Archibald from zero to production in under three months — an AI art advisor delivered entirely via email. No app, no dashboard: email a question, get multi-year market analysis in seconds. Under the hood: a hybrid text-to-SQL + vector search architecture over 8M+ auction records and 50k+ unstructured documents, cutting research time by 80% and hallucinations by 90%. From data ingestion to cloud deployment, I own the full stack.
Before that, I spent several years in the art market — consultancy and sales, moving between New York, London, and Antwerp. Along the way, I collaborated with All Ears in London, building AI-generated audio content with local TTS and voice cloning (Chatterbox) for clients including Tate Modern and Goldsmiths University.
