Cloud & DevOps Engineer

About

With over 6 years at the University of Bordeaux’s IT Department, I evolved from a Windows Systems Administrator to a DevOps Engineer, managing complex infrastructures and deployments for thousands of users. My skills cover automation, container orchestration and CI/CD, Linux/Windows systems, Infrastructure as Code, Azure, and Active Directory ecosystem.

Currently enhancing my Cloud and DevOps expertise by pursuing Azure AZ-104 and Kubernetes CKA certifications, while exploring AI solution integration. I’m seeking remote freelance or full-time roles worldwide.
