Germany
Message

At Zeppelin, I introduced Kubernetes, infrastructure as code, and CI/CD, helping lower infrastructure costs, improve availability, and increase release frequency. I also built cloud infrastructure on AWS for company-wide single sign-on and a modular microservices platform.

I grew and led a 15-person team while staying active in development, architecture, and DevOps. I contributed to container infrastructure for the Zeppelin website relaunch and e-commerce platform.

More recently, I automated server provisioning and Docker deployments, and migrated monitoring from Datadog to Grafana. In my current role at prodactive GmbH, I develop a construction equipment and formwork management platform, including its CI/CD pipelines and business modules.
