Back to original languageAbout Thierry
Senior full stack developer and AI architect, I design and deploy applications integrating AI agents, RAG, and machine learning—from proof of concept to production.
What sets me apart: 20 years of complex application development combined with operational AI expertise. Where a data scientist builds a model in a notebook, I deploy it in a scalable architecture, with a real API, monitoring, and a user interface.
My areas of expertise:
• Production AI Applications — Business conversational agents, multi-agent systems, RAG pipelines for enterprise knowledge bases, LLM integration (Claude, OpenAI) into existing applications.
• Full Stack Development — High-performance web and mobile applications (React, Angular, Node.js/NestJS, React Native), real-time architectures (WebSocket, Kafka), REST and GraphQL APIs.
• Applied Machine Learning — Real-time predictive models, feature engineering, deployment of ML services in production (FastAPI, data pipelines).
I have worked for major clients (Le Monde, Orange, Leroy-Merlin) and startups (Klaxoon, Planity, Hitch) on projects where technical quality, autonomy, and deadline adherence are non-negotiable.
Co-author of technical books (Packt, Manning, Eyrolles), active contributor on StackOverflow (+1900 Angular answers), speaker (RennesJS, Malt Academies).
