I contacted Mathieu to help me frame and improve the behavior of an LLM agent deployed locally, without internet access. From the first exchange, he understood the constraints of my environment, asked the right questions, and structured a very clear approach.
The work session was of high quality, combining technical expertise, functional perspective, and concrete, directly usable recommendations. The deliverable provided after the session is precise, concise, and will clearly guide the next steps of the project.
Beyond his skills in generative AI and agent structuring, Mathieu stands out for his seriousness, his teaching ability, and his capacity to propose context-adapted solutions. I highly recommend his support to anyone looking to implement robust and relevant LLM systems.
