DevOps Engineer

The experiences from over 10 years in various companies led to the step into self-employment in 2022. As an independent DevOps engineer, I now leverage my entire technical range to support companies in modernizing critical IT infrastructures. My focus lies on Ansible-based automation, container orchestration with OpenShift and Kubernetes, and implementing security best practices in hybrid cloud environments.

Since 2022, I’ve been supporting companies from the insurance, energy, and IT system house industries in strategic transformation projects. At Baloise, I developed automated migrations on Windows servers using Ansible, Docker containers for OpenShift, and Helm charts for ArgoCD over two years (December 2022 to December 2024). Technical project planning and coordination of multiple external service providers were part of my responsibilities, as well as advancing MariaDB databases for cloud-native deployments.

At Uniper (June 2025 to November 2025), I planned and provisioned Azure cloud infrastructure using Terraform and implemented CI/CD pipelines with GitHub Actions and Azure DevOps. Containerizing applications in C# and Python, along with their automatic deployment via Azure IoT Hub to edge devices, formed the technical focus of this project. Network planning, debugging, and analyzing undocumented code were part of the daily routine.

The technical range extends from multi-cluster OpenShift setups to GitOps pipelines and comprehensive monitoring landscapes with Prometheus and Grafana. At keepbit (June 2025 to ongoing), I administer Jira and Confluence Data Center instances, customize workflows and automations, and advise on optimizing project management and knowledge management processes.

As an independent consultant, I consciously choose projects that align with my values: technical excellence, open communication, and peaceful civilian development. This orientation enables long-term partnerships with clients seeking not just technology, but sustainable solutions.

My clients particularly appreciate the solution-oriented approach, the ability to quickly familiarize myself with new technologies, and direct, clear communication. The combination of 4+ years of Atlassian expertise and full-stack DevOps competence is rare and makes me the ideal partner for companies modernizing both developer tooling AND infrastructure.

Core Competencies:

• DevOps engineering and CI/CD pipeline development (GitHub Actions, Azure DevOps, Jenkins)
• Infrastructure as Code (Ansible for Linux & Windows, Terraform, Helm charts)
• Container technologies (Docker, OpenShift, Kubernetes, ArgoCD)
• Cloud platforms (Microsoft Azure, AWS, hybrid cloud architectures)
• Linux & Windows Server administration and automation
• Atlassian system administration (Jira, Confluence, Bitbucket)
• Monitoring and observability (Prometheus, Grafana, TIG Stack)
