Yann Soubeyrand is an experienced DevOps and Platform Engineer with 11 years building and operating cloud-native infrastructure across Kubernetes and OpenShift on AWS, Azure and Exoscale. He designs IaC (Terraform, Pulumi), Helm charts and GitOps pipelines (Argo CD), and has run high-traffic SaaS platforms and observability stacks (Prometheus/Thanos, Fluent Bit/Fluentd, Elasticsearch). A hands-on systems programmer who contributes to notable open-source projects like fluent-bit and CFEngine, he focuses on code robustness—fixing parsing, memory and build issues—and performance-minded tooling in Go. Certified CKA and an Ensimag engineering graduate, he blends embedded/Linux low-level roots with scalable platform engineering practices. Unusually for a platform engineer, he also has a background as a competitive skier, reflecting discipline and a taste for high-performance environments.
