About Arnaud

Experienced Cloud Solutions Architect, I design, deploy and optimize innovative, secure and resilient cloud infrastructures. With expertise on AWS, Azure, I transform business needs into robust, scalable solutions that comply with security standards by adopting a FinOps approach to cost control.

I intervene upstream to frame needs, steer technological choices (IaaS, PaaS, SaaS) and define effective migration paths while integrating a devops culture.
