AI Software Engineer based in Brazzaville, Congo, with 5+ years of experience going from frontend development to full-stack architecture and AI-powered products.
I build AI matching and data intelligence systems that combine embeddings, vector search and LLMs, and I ship them end to end, from the database to the UI.

Rabotka, Founder & CEO / Lead AI Engineer A WhatsApp-first job marketplace for Africa. I lead the architecture of its AI matching system: embeddings, vector search with Qdrant and an interest graph that recommend jobs to candidates and candidates to employers. I own the full lifecycle, from product specs to backend, frontend, infrastructure and production.
