From the CI/CD pipeline to the Kubernetes cluster: I automate, harden and operate critical platforms.
DevOps profile
20+ years in critical Linux production, including end-to-end DevOps practice: delivery industrialization (GitLab CI, Jenkins, Ansible Tower), Infrastructure as Code (Terraform, Ansible, Salt) on the OpenStack/NUBO sovereign cloud, Kubernetes/Helm packaging and operations (Onyxia), containers (Docker, Podman, Apptainer) and observability (Prometheus, Grafana, Centreon). Technical referent at the French Ministry of Finance, Radio France, BnF, INPI and Naarea.
