Why Clients Hire Me

01

Production RAG at scale

I've shipped a RAG pipeline on 1.1M+ live news articles with sub-second latency and an 80M-triple RDF knowledge graph — not a demo, a live production system used daily by journalists.

02

Research-grade ML background

Former Research Engineer at LIMOS, Université Clermont Auvergne (France) — working on ML for medical research under European Medical Council supervision. I bring academic rigour to production problems.

03

Full-stack delivery — no handoff needed

I own the entire product: vector DB and LLM pipeline, scalable REST/GraphQL APIs, normalized database schemas tuned for latency, and React/Next.js frontend. One person, one contract, no coordination overhead.
