About Me

Engineer by craft,
Paris by choice.

I'm a Senior Platform Engineer with 7 years of experience in DevOps and cloud, mainly on Azure. I design and run self-service Kubernetes platforms that give development teams what they need: golden paths (Terraform modules, Helm charts, GitHub Actions workflows), GitOps with ArgoCD, observability, autoscaling and cost control (FinOps).

I work with several product and infrastructure teams every week: I set platform standards, remove blockers and mentor engineers. Azure is my production environment; I also practise GCP (GKE, Terraform, Workload Identity Federation) through training and a personal project. Day to day, I use GitHub Copilot and MCP servers, and I take part in a Claude Code POC.

Based in Paris, Île-de-France. Fluent in French and English.
