Infrastructure and DevOps engineer with 15+ years running critical, regulated environments. I automate everything with Ansible, Terraform and Packer, build and operate private clouds on OpenStack, Proxmox, VMware and Ceph, and secure access with HashiCorp Vault and Tailscale. Always learning, always experimenting, and always looking for better open-source solutions.
I have a background in physics and R&D, and over 15 years I have run critical, regulated environments: a global hosting provider (OVH), telecom (Bandwidth), public safety communications (Thales) and medical technology (IBA). I am currently a System Infrastructure Engineer at IBA in Louvain-la-Neuve, with on-call duty 7 days a month.
My work focuses on Infrastructure as Code and automation with Ansible, AWX, Terraform and Packer, and on building and operating private clouds on OpenStack, Proxmox, VMware and Ceph. I have led multi-datacenter migrations, disaster recovery platforms and security and compliance work for NIS2, SOX and ISO 27001. I am bilingual French/English.
