Back to original languageAbout Yann
DevOps Engineer expert in Cloud-Native ecosystems and certified Kubestronaut (CNCF: CKA, CKAD, CKS, KCNA, KCSA), I support companies in the automation, security, and production deployment of their critical infrastructures.
Currently a DevOps Engineer at FDJ (Française des Jeux), I work in very high-load environments where high availability, resilience, and absolute automation are non-negotiable prerequisites.
Rooted in the GitOps culture, I maintain an advanced personal lab to test Kubernetes versions in real conditions, simulate failures (chaos engineering), harden security, and validate cutting-edge architectures before any large-scale deployment.
My Technical Expertise:
Kubernetes & Cloud-Native: Architecture, administration (kubeadm, k3s), CNI, storage, RBAC, troubleshooting, and security.
Infrastructure as Code (IaC): Terraform, Ansible, complete infrastructure automation.
Containerization: Docker, Docker Compose, multi-stage image optimization.
CI/CD: GitLab CI, Jenkins, automated pipelines, and DevSecOps scan integration.
Cloud & Hosting: AWS (foundations), VPS / Bare Metal (OVH), hybrid approaches.
Development: FastAPI (Python), PostgreSQL, DevOps tooling, and internal APIs.
Observability & Security: Log centralization, monitoring, audits, and hardening.
What I Bring You:
Audit & Redesign: Migration, security, and optimization of Kubernetes clusters.
Industrialization: Elimination of manual tasks and reproducible deployments.
Containerization: Transitioning applications to microservices architectures.
Troubleshooting: Rapid diagnosis and stabilization of clusters or pipelines in production.
Suitable for the requirements of large corporations as well as the flexibility of start-ups, I favor pragmatic, reliable, and documented solutions. Let's discuss your technical challenges today.
