About Pierre

Computer engineer turned "AI engineer" since 2022, I design and deploy autonomous agents and solutions based on large language models ("LLMs" or "generative" AIs). Passionate about their potential and with experience in both large corporations and startups, I implement these technologies pragmatically to serve business challenges. My approach is informed by an interest in social sciences and combines creativity, rigor, and collaboration at every stage.

AI / LLMs / Autonomous Agents Expertise

My expertise covers a wide range of areas: from advanced chatbots to content generation systems, data analysis, and the design of complex agentic behaviors. I support you at every stage of your project, from initial design to production, adopting an approach focused on innovation, efficiency, as well as rigorous testing and continuous evaluation.

Generative AI Strategy and Training

Through continuous monitoring, I help you define an AI strategy tailored to your company, with personalized recommendations based on the latest technological trends. I also provide training for your teams on generative AI tools, organizing practical workshops and awareness sessions to accelerate their adoption and maximize their impact on your operational processes.
