🧠 Operational Focus

Engineering at the intersection of robust technical infrastructure and clear communication.

Leveraging over two decades of Linux systems engineering experience alongside a professional background as a journalist and editor (profile on kress.de), with a specialization in translating complex infrastructure states into stable, documented, and low-maintenance platforms.

Long-term operational quality is driven by disciplined simplicity—restricting tool sprawl, enforcing clear standards, and providing meticulous documentation.

⚡ Core Principles

Low Maintenance Over Tool Overhead: Building architectures, not tool towers. If a problem can be solved with a systemd service or a clean Ansible playbook, avoid deploying Kubernetes. Stability comes from leaving out the unnecessary.
Documentation as Code: Documentation is not an afterthought, but a core deliverable. Incomplete or outdated documentation is treated just like buggy code.
Arch Linux First: Development and desktop environments are built on Arch Linux, valuing control, the rolling release model, the AUR packaging ecosystem, and clean, transparent PKGBUILDs.
System Predictability: Designing and documenting systems for absolute logical consistency, clean schemas, and highly predictable runtime behavior to ensure zero late-night fire fighting.

⭐️ Highlight Project: BearWave 📻

Over the past few weeks, I have put intensive effort into developing BearWave. It is a focused, native KDE internet radio player for Linux, built with C++, Qt 6, QML, and KDE Frameworks.

Why I built it: Many Linux players are bloated media centers. BearWave does exactly one thing right: play web radio quickly and efficiently, without getting in the system's way.

Seamless Plasma Integration: Full MPRIS support (control via media keys and panel widget) and a system tray mode for unobtrusive background operation.
Resilient & Offline-First: Intelligent JSON caching for station data and automatic cover art caching to minimize load times and resume streams instantly.
Bilingual & Localized: Dynamic UI translation (English/German) and country name localization for over 250 countries, including automatic flag generation from ISO codes.
Arch Linux Native: Cleanly packaged and installable via the Arch User Repository (bearwave-git).
