About Me

I build Kubernetes platforms that scale, secure, and simplify complex systems.

Senior Platform Engineer with 8+ years of experience designing and operating cloud-native platforms across on-premise and cloud environments.

I specialize in Kubernetes, GitOps, and platform automation — with a strong focus on reliability, security, and developer experience.

My work includes developing Kubernetes Operators in Go, designing secure software supply chains, and enabling teams through self-service platforms.

Experienced in regulated environments (gematik / healthcare), where compliance, security, and uptime are critical.

What I Do

  • Build and operate production-grade Kubernetes platforms
  • Design GitOps-based delivery systems (ArgoCD, Helm)
  • Develop Kubernetes Operators and tooling in Go (Kubebuilder)
  • Automate infrastructure using Terraform, Ansible, and Nix
  • Design secure software supply chains (SBOM, container security)
  • Enable teams with self-service platform capabilities

Professional Experience

Senior DevOps / Platform Engineer

May 2020 – Present

Led the design and operation of highly available Kubernetes platforms across on-premise and cloud environments.

Key Highlights

  • Built and operated multi-cluster Kubernetes platforms supporting critical workloads in healthcare environments
  • Developed Kubernetes Operators in Go (Kubebuilder), reducing manual platform operations significantly
  • Established GitOps-based delivery models (ArgoCD, Helm), enabling fully reproducible deployments
  • Designed secure CI/CD and container build pipelines (Kaniko, SBOM, supply chain security)
  • Implemented observability platforms (Prometheus, Grafana, OpenTelemetry, Loki) for end-to-end visibility
  • Delivered infrastructure for multiple gematik projects handling sensitive and high-volume data flows

Impact

  • Reduced manual operational effort by >70% through automation and platform engineering
  • Improved deployment consistency and reduced configuration drift across environments
  • Enabled faster release cycles through GitOps-based workflows
  • Increased system observability, significantly improving incident detection and resolution times
  • Supported high-availability systems with strict compliance and security requirements
