About Jean

AI Engineer specialized in Computer Vision, NLP, and LLMs, graduated from ISAE-Supaero and Polytechnique Montréal.

I help companies design and deploy concrete artificial intelligence solutions: real-time object detection, NLP pipelines, LLM orchestration systems in local and constrained environments.

At ALTEN Labs, I designed an industrial LLM orchestration system from scratch (100% local deployment, modular architecture, multimodal voice/text/image interface) while leading a team of 5 to 10 engineers.

At IRIT, I worked on text clustering and classification algorithms for collaborative decision support systems.

I am comfortable with both research and modeling (PyTorch, scikit-learn, HuggingFace) and production deployment (Docker, FastAPI, Git) and integration into existing environments.
