# Bastien Youssfi

> AI engineer based in Paris. I design and ship production AI systems for French companies: document extraction, RAG, agents and anonymisation — built for confidentiality, traceability and data sovereignty.

## Facts

- Bastien Youssfi is an AI engineer based in Paris, France.
- He builds production AI systems: document extraction, retrieval-augmented generation (RAG), agents and document anonymisation.
- The systems he builds serve French companies with confidentiality constraints — law firms, architecture practices, industrial SMEs and the museum sector.
- They run under Zero Data Retention, on French hosting, and no binding action is taken without human validation.
- He also operates his own SaaS products under Updev Solutions.

## What I build

- **Document extraction** — PDFs and scans into structured data (Python · OCR · LLM)
- **RAG & retrieval** — Sourced answers over your documents (pgvector · LangGraph)
- **Agents** — Tools, guardrails, human approval (Claude · Function calling)
- **Mobile apps** — iOS and Android, shipped to the stores (React Native · Expo)
- **Audit & scoping** — Mapping, use cases, roadmap (Data · Mapping)
