Systems ▼
I'm especially interested in the systems around software development: how applications are built, deployed, tested, integrated, and operated reliably in real production environments. In practice, that means working with tools like GitHub Actions, Docker, Kubernetes, ArgoCD, Splunk, and SAP BTP Kyma in an enterprise setting, while also thinking about architecture, security, maintainability, software testing, and smooth cooperation between multiple systems. I also explore how AI tools can support product features and development workflows in practical, responsible ways.

Collaboration ▼
Collaboration has been a central part of my work for years. Alongside strong teamwork and communication skills, I bring practical project management experience from agency work, formal training in project and process management, and additional project management education as part of my bachelor's degree. I enjoy working closely with customers and stakeholders to shape projects, processes, and digital products in a way that fits their goals, works in practice, and addresses the actual underlying need.
