Description

I am Jean Christophe, a DevOps / Cloud & Kubernetes expert with 8 years of experience.

What I bring concretely:

Reliable and secure CI/CD pipelines (GitLab CI / GitHub Actions, dedicated runners, multi-environments)

Industrialized GitOps & deployments with ArgoCD/FluxCD, Helm, and best practices for configuration management

Infrastructure as Code with Terraform: provisioning, modules, standards, environment separation

Kubernetes & SRE: operations, hardening, observability (Prometheus, Grafana, Alertmanager, Datadog, OpenTelemetry, Alloy)

Team support: skills transfer, patterns, runbooks, and autonomy building
