Sylvain Rabot is a seasoned SRE and infrastructure architect with 16 years of experience building and operating scalable cloud-native systems from Bordeaux, France. He has led end-to-end infrastructure programs—designing multi-account AWS environments, EKS fleets with Cilium and Karpenter, GitHub Enterprise CI/CD, and centralized observability using Prometheus/Thanos/Grafana—while founding and managing SRE teams. A pragmatic engineer, he combines deep operational experience (large hosting fleets and multi-datacenter NAS at F-Secure) with hands-on DevOps: IaC with Terragrunt/Terraform Cloud, FluxCD-driven Kubernetes bootstraps, and advanced access controls using Entra ID and custom IAM. Sylvain is also an active open-source contributor to high-profile CNCF projects (ingress-nginx, traefik, kustomize, prometheus, thanos), where he’s improved memory and API interactions, certificate/tls metrics and cloud provider integrations. He favors measurable, maintainable improvements—evident in work that optimizes controller memory, hardens storage integrations and upgrades build tooling—and brings a habit of small, high-impact fixes alongside architectural vision.
