Platform engineering & GitOps
Kubernetes platforms built to be operated: ArgoCD hub-and-spoke, OpenTofu, Helm and Kustomize, Kyverno, observability, secrets and certificates – from first cluster to handover.
I'm Felix, a cloud and platform engineer based in Hamburg.
I started my journey in theoretical computer science and distributed systems, then spent many years writing software – backend services, APIs and tooling in Go, Python, Java and TypeScript. Kubernetes has been part of that work since 2015, shortly after its first release.
Security came along the way – a master's thesis on detecting advanced persistent threats at Fraunhofer Singapore, then blue teaming and threat hunting at Tenzir, while building Threat Bus, an open-source layer for sharing threat intelligence between security tools. After that, I worked as SRE for German government infrastructure.
That path shapes how I build platforms today: operability, isolation and cost are part of my designs from day one – and the team should be able to run what I hand over without me.
Since 2022 I have been working independently, as architect and hands-on engineer in one – I've led a full production migration to Scaleway, built platform foundations on STACKIT and reviewed large Kubernetes environments. My work is AI-accelerated; the decisions behind it rest on fifteen years of building and running systems.
