About Simon

AI Tech Lead & AI Solutions Architect in production. Specializing in intelligent agents, GenAI architectures, and MLOps / GenAIOps industrialization.

Graduated from CentraleSupélec (Artificial Intelligence major), I have been supporting a wide variety of organizations for nearly 10 years: large industrial and tech groups (EDF, Capgemini, Total), satellite operators (Space42), public institutions (Unicef, ministries), pharmaceutical labs (Pfizer, AstraZeneca, Moderna), and hyper-growth startups. From POC to scaled production.

▸ MY EXPERTISE
• Agentic Architectures: Advanced RAG, multi-task agents, tool-use, contextual memory, multi-agent orchestration
• GenAI Industrialization: LLM deployment (vLLM, TensorRT-LLM, quantization), guardrails, evaluation, observability
• End-to-end MLOps & GenAIOps: Model versioning, CI/CD, monitoring (drift, latency, quality), feedback loops
• AI Audit & Compliance: Explainability, robustness, AI Act, GDPR
• Strategic AI Framing: Executive roadmap, build vs buy, sizing, ROI

▸ STACK
Python, PyTorch, LangChain, LlamaIndex, vLLM, TensorRT-LLM, Hugging Face, MLflow, Ray, Triton, Azure OpenAI, AWS Bedrock, OpenAI, Mistral, Claude (Anthropic), Spark, Kubernetes.

▸ MY MISSIONS
