Maximilian Marschall is one of Austria's first five Kubestronauts and a platform engineering ambassador. He is a platform engineer passionate about Kubernetes, GitOps, and observability. He is one of the creators of Janus, an open-source authentication proxy that enforces fine-grained, multi-tenant access control for observability stacks by rewriting queries at runtime. When he is not building production-grade platforms, he is expanding his homelab, a self-hosted infrastructure that rivals enterprise-level cloud setups.
