Platform Engineering Expertise

Open-source infrastructure & automation code

Terraform modules, Ansible roles, GitLab CI/CD templates, Kubernetes Helm charts, NixOS and Linux configuration, and deployment examples I have built and use. Shared as-is — useful starting points rather than finished products.

About

I am Adrian Wyssmann, a platform engineer. I work on Terraform modules, Ansible roles, Kubernetes and Cloudflare Zero Trust, and I share that work openly on GitLab — so the foundations stay readable and yours to own.

I also build and run my own software; EventCompass is my first SaaS solution.
