Bastien Youssfi

Hi, bonjour, AI engineer

I’m an AI engineer in Paris, and I mostly build for , on problems where confidentiality and traceability matter as much as the result.

I design, build and ship AI products to production. Not demos — systems that hold up: document extraction, RAG, agents, anonymization.

Zero Data Retention, French hosting, and never a committing action without human approval. I also run my own SaaS under Updev Solutions.

I build out of passion, and out of optimism: done well, this technology makes people more capable. Watching a thing actually work is still the best part.

You can reach me by email, or see the rest on GitHub and LinkedIn.

In short

  • 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 guides the work: reliability, traceability, sovereignty — and the sense that the best of it is still to be built.
