Hi, I'm Patrick 👋

Senior Software Engineer, Infrastructure @ Camunda 📍 Austria · 🌐 Remote

I'm a platform engineer with a programming background. I started as a Java developer building tools in the financial sector, then deliberately moved deeper into the infrastructure stack — from application code to CI/CD pipelines, to containerizing microservices, to building entire Kubernetes platforms from bare metal up. Today I build software to make other engineers more productive.

I am a strong advocate for an async-first workstyle (since the 2020 shift), valuing deep work, transparent group communication, and respecting others' time over synchronous interruptions.

🔧 What I do at work

Owner of Camunda's developer platform serving 100+ engineers across 10+ product teams — CI/CD infrastructure (GitHub Actions self-hosted runners on EKS, preview environments via Github Labels), Kubernetes clusters (GKE + EKS), container registries (Harbor), dependency management (Renovate), monitoring, and cross-team platform services.

🏗️ What I build for fun

HomeRackerA fully modular 3D-printable rack-building system

Stars Forks Website Discord

I created HomeRacker because I was dissatisfied with existing 3D-printable rack solutions — too specific, too rigid, too many adapters. HomeRacker is a fully parametric, open-spec system that can build anything from a Raspberry Pi mini-rack to a 10"/19" server rack to a bookshelf. No printed supports needed, no tools required for assembly.

Also built scadm (PyPi) — a zero-dependency Python package manager for OpenSCAD libraries. pip install scadm
