About Jérôme
With over ten years of experience, I specialize in developing advanced agentic AI systems and cognitive simulations at Sanofi. My work focuses on leveraging tools like AWS Bedrock AgentCore, Strands SDK, and Retrieval-Augmented Generation to build production-grade systems that integrate psychological principles into AI design. My initiatives include prototyping and deploying agentic cognitive simulation platforms and designing scalable architectures compliant with pharma industry regulations.
By combining a background in clinical psychology with technical expertise, I apply validated psychological frameworks such as Big Five/OCEAN and Atkinson-Shiffrin memory models to agent design. This approach ensures consistency, memory retention, and character fidelity in AI systems. My commitment lies in creating innovative solutions that drive impactful and regulated advancements in AI technologies.
