Back to original languageAbout Christophe
Does your infrastructure need to scale while adhering to strict security constraints (ISO 27001, SecNumCloud, banking regulations)? I design and operate secure Kubernetes platforms, from design to production, in both cloud and bare-metal environments.
What I bring concretely:
🔧 Infrastructure & Kubernetes — Design and deployment of K3s/K8s/EKS clusters in production. VMware ↔ Kubernetes interconnection (LoadBalancing, StorageClass). Full automation with Terraform, Ansible, and Helm. GitOps with FluxCD/ArgoCD.
📊 Observability & Reliability (SRE) — Design of complete monitoring stacks: Grafana, Prometheus, Loki, Mimir, OpenTelemetry. Incident management, on-call duties, and SRE culture.
🔒 Security & Compliance — Certified ISO 27005 Risk Manager and EBIOS RM. OS Hardening (RHEL, Debian), Cilium/IPSec Network Policies, XDR (Wazuh) and IDS (Suricata) deployment. Participation in ISO 27001 audits.
📉 Cost Optimization — Reduction of €1,000/month on a Symfony infrastructure at Swibeco. Rationalization of AWS/OVH cloud resources.
Key Experiences:
- SRE at OVH on the SecNumCloud "Baremetal Pod" product: OpenStack on Kubernetes, SED encryption, monitoring of critical components (Neutron, Nova, Ironic, Keystone)
- Lead Infrastructure Designer at CFCAL (banking sector): bare-metal K3s cluster on VMware with regulatory compliance
- Lead DevOps at Swibeco (Switzerland): supporting teams, ISO 27001 audit, CI/CD automation
- SRE & Cloud Engineer at Preligens: multi-product technical referent (bare-metal + cloud), 20 servers
- Technical Stack: Kubernetes (K3s, EKS), Terraform, Ansible, Helm, Docker, Cilium, Jenkins, GitHub Actions, Grafana, Prometheus, Loki, OpenTelemetry, AWS (EKS, EFS, EBS, S3), OVH, VMware, FluxCD, Packer, Wazuh, Suricata, Keycloak, PostgreSQL, Redis
