End-to-end delivery
From raw data to production system. I own the full pipeline — ingestion, modeling, deployment, dashboards — so nothing falls between the cracks.
About
Florent Lin
AI Engineer
I turn complex data into systems that ship, scale, and make decisions easier.
Based in Paris. Available for freelance.
• HOW I WORK
Domain immersion
Railway safety, urban planning, franchise matching. I learn your business deeply because the best models come from understanding the problem, not just the data.
Research-grade foundations
ENSAE Paris trained me in statistics, optimization, and ML theory. That rigor means my systems are reliable, not just impressive in a demo.
