Freelancer profile translated to English.

Description

I develop and deploy GenAI solutions in production: agents, RAG, orchestration, and workflows.

Most GenAI POCs never make it to production—not because the tech doesn't work, but because no one has planned for what happens after the demo.

What I bring:

✓ Continuous evaluation — knowing when the model drifts

✓ LLM Monitoring — understanding what's happening in production

✓ FinOps — avoiding the exploding bill

✓ Context engineering — prompts that last over time

Background:

- 2025: GenAI Startup Co-founder — voice agent, multi-agents, real-time AI editor, from scratch in production

- +10 years in IT consulting for large accounts (Cnam, France Travail, Douane)

Additionally: technical scoping and dev team training.

Speaker (DevFest, TechReady) · Co-organizer GenAI Nantes meetup

Available for GenAI missions, 2-6 months.

Based in Nantes. I work remotely, on-site in Nantes, or with flexible in-person arrangements (Paris, Grand Ouest).
