Platform Engineer at Cegid who led 250+ zero-downtime migrations to its SaaS ERP.

At Cegid, I led 250+ client migrations from on-premise to the SaaS ERP, executing zero-downtime cutovers outside business hours.

I operate and scale cloud instances and databases on Oracle Cloud Infrastructure, managing the infrastructure lifecycle from integration to production with Product and Developer teams. I also modernised observability with Datadog to improve platform health visibility and support proactive incident resolution.

At Claranet, I led migrations for CAC 40 clients, moving 2,000+ instances from on-premise to Azure and AWS. I advised enterprise clients on highly available architectures and cloud adoption.

Across my DevOps roles, I automated infrastructure and deployment pipelines, modernised legacy applications into microservices, and supported monitoring and incident response. My work has included AWS, Azure, Kubernetes, Terraform, and Linux.
