Introduction
Senior AI Engineer specializing in agentic AI and multi-agent systems. I design and ship production-grade LLM agents, combining a decade of fullstack engineering (React / TypeScript / Node / AWS) with a background in clinical psychology applied to agent design. At Sanofi, I originated and led PersonaLab, a multi-agent cognitive simulation platform presented at VivaTech 2026. I architected the full system solo: a Python/FastAPI backend on AWS Bedrock AgentCore, multi-agent orchestration with the Strands Agents SDK, semantic memory on OpenSearch Serverless, structured cognitive turns, and a React 19 frontend. My differentiator: I apply validated psychological frameworks (Big Five / OCEAN, OCC, BDI, CAPS, Atkinson-Shiffrin memory models) to agent design, producing agents with consistent personality, memory retention and behavioral believability. This bridges rigorous engineering and the cognitive science of how believable agents actually work. Core stack & focus: - Agentic AI: multi-agent orchestration, tool-calling, agent memory, evals - LLMs: Claude (Sonnet/Haiku), RAG, prompt & context engineering, MCP - Cloud: AWS Bedrock AgentCore, Lambda, DynamoDB, OpenSearch Serverless - Fullstack: React, TypeScript, Node.js, FastAPI, Python Open to senior AI / Agentic AI Engineer and AI Architect roles — on-site in Paris or fully remote (EU / US).
