About Stephan
I’m a Senior Engineer with over 20 years of experience in designing, operating, and automating complex IT infrastructures. My core expertise includes Kubernetes (TKG, RKE2), GitOps (FluxCD, Argo CD), Helm, Kustomize, CI/CD pipelines, Harbor registries, observability stacks (Prometheus/Grafana), and container security.
I build reliable, scalable, and secure platforms and automate everything from cluster lifecycle to application delivery.
Over the years, I have engineered Linux, virtualization, storage, and backup systems, automated environments using Ansible, Puppet, Bash, and Python, and delivered enterprise-grade solutions across healthcare, finance, and research sectors.
I am a CNCF Kubestronaut, holding the full Kubernetes certification track — CKA, CKS, CKAD, KCNA and KCSA — along with additional Red Hat, OpenShift, and VMware certifications. I bring deep technical knowledge, strong problem-solving skills, and a collaborative, customer-focused mindset. I enjoy tackling complex challenges and helping clients design stable, secure, and efficient systems.
