Stéphane Monfort — CTO & Senior Cloud Architect in Paris

About

End-to-end tech expertise, from IT strategy to product delivery

I built my expertise over the past 18 years, from software architect at IBM to executive committee member at CACD2, the digital factory of Crédit Agricole Group, where I served as CTO for 7 years.

What sets me apart: a broad scope of action. Hands-on when needed, I can define and implement complex architectures, challenge technical choices and co-design solutions with teams. I also bring a strong strategic vision, ensuring technology is aligned with business goals.
