Jean-Sébastien Padoan

J’accompagne les entreprises dans la conception et la mise en production de systèmes d’IA (LLM, RAG, agentic workflows).

I help companies design, build, and scale production-grade AI systems.

With over 20 years of experience as a hands-on architect and CTO, I specialize in generative AI systems (LLMs, RAG, agentic workflows) and cloud-native architectures.

I work with startups and large organizations to turn AI concepts into real, scalable products—from architecture design to production deployment.

Key expertise:

• LLM pipelines, RAG, embeddings, vector databases

• Agentic systems and tool orchestration

• AI platform architecture (cloud + hybrid inference)

• Performance & cost optimization

I combine deep technical expertise with strong execution and business impact.

Typical engagements:

• AI / GenAI architecture audit

• RAG / LLM system design & implementation

• AI platform architecture (enterprise)

• Fractional CTO (AI strategy & delivery)
