Back to original languageAbout Lucas
AI & custom development expert — 200+ projects delivered for SNCF, Engie, RTE, L'Oréal, Air France, CEA...
I transform your business problems into AI solutions that actually work:
• Autonomous AI agents (multi-agent, orchestration, tool-calling)
• RAG & document processing (400,000 docs analyzed for the Administration)
• Model fine-tuning (LLM/SLM, vision, multimodal)
• Custom business software — often amortized within 1 year of SaaS license
Client results:
→ -90% quote generation time (aerospace)
→ Signal EcoWatt: forecast of the French electricity grid 10 days ahead
→ Large-scale document extraction (Bostik, sovereign environment)
Graduated from CentraleSupélec, coding since 2008, professional since 2014.
My obsession: robust, measurable AI tools in production — not POCs that stay in a drawer.
