Julien Nguyen

DevOps Engineer · Freelance

DevOps engineer from Paris. Since 2022 I have built and run production infrastructure: Terraform and Ansible, Kubernetes on AWS, Scaleway and OVH, GitOps with ArgoCD, and observability with OpenTelemetry, Datadog and Elastic. In 2026 I went freelance: I design infrastructure for small businesses, and I build a few iOS apps of my own, from code to App Store release.
