What I'm Into
Cloud Native & Kubernetes

OpenZEV
An open source platform for operating and billing (v)ZEV energy communities — my project for making local energy sharing easier to run.

Kubernetes Consulting
A customer success story about hands-on Kubernetes consulting and platform engineering work.
Kubernetes Resource Requests for GitLab Jobs
A talk at Cloud Native Zürich on right-sizing Kubernetes resource requests for GitLab CI jobs, based on work done for Die Mobiliar.
