DevOps & Cloud Platform Engineering
Terraform · Azure · Kubernetes · GitOps · CI/CD · Observability

I am a System Engineer moving into DevOps and Platform Engineering roles. I build small, reproducible platforms that make infrastructure changes, delivery controls and recovery paths inspectable through code, tests, CI evidence and runbooks.

My background combines systems integration with International Information Systems (B.Sc.). I am looking for a full-time DevOps, Cloud Platform or Infrastructure Automation role around Augsburg, hybrid in Munich or remote across Germany.

Portfolio · Email

Start here: 10-minute review path

  1. Azure Platform IaC
    Terraform, AzureRM v5, secretless GitHub OIDC, policy tests, security scans and a protected apply path.
  2. GitOps Platform Lab
    Kubernetes Desired State, Argo CD reconciliation, Kustomize overlays, SLOs, observability and a tested recovery exercise.
  3. Incident Automation Lab
    Prometheus, Grafana, Loki and OpenTelemetry signals correlated into explainable, approval-safe incident triage.
  4. Azure & Microsoft 365 Tenant Guard
    Read-only inventory, deterministic governance checks, evidence exports and approval-gated remediation.

DevOps proof map

Capability Inspectable evidence
Infrastructure as Code Terraform modules, native policy tests, AzureRM contracts and documented teardown
CI/CD controls Pull-request verification, security scans, OIDC plan identities and protected manual apply
Platform operations Kubernetes, Kustomize, Argo CD self-healing and Git-based drift recovery
Observability Prometheus metrics, Grafana dashboards, Loki logs, OpenTelemetry traces and SLO burn rates
Reliability Failure injection, runbooks, recovery exercises and explicit production boundaries
Supply-chain safety CodeQL, Trivy, Checkov, dependency audits, SHA-pinned actions and SPDX SBOMs

How I operate

  • Git records the intended state; automation makes changes reviewable and repeatable.
  • Short-lived identity and least privilege replace long-lived cloud credentials.
  • Read-only discovery comes before any approval-gated change.
  • Tests, execution captures and runbooks turn a demo into operational evidence.
  • Limitations stay visible. These public labs do not claim customer or production-cluster usage.

Additional work is available in the engineering portfolio, including data quality automation, a private-AI platform lab and product engineering across Swift, Go and Cloudflare Workers.
