Native Development

C/C++ (♥), Python, Java or Kotlin. I speak them all! My favourite rendering APIs? Vulkan, OpenGL and GLSL. Librarys? Vulkan SDK, libcurl, GLUT, SDL2 and GTK+/wxWidgets. And did you know that I’m the co-maintainer of Open-Smartwatch?

Web Development

PHP, HTML, CSS, JS, and TS - you name it! Libraries and Frameworks? Python Flask / FastAPI (with Poetry), Angular, Cordova and Electron. Things I know… NodeJS/NPM/NVM and all its derivatives.

Development operations

DevOps? Of course! Gitlab CI, Docker and Kubernetes: Starting with just some code-format-checks up to tested, scaled, auto-deployed and prodution-ready apps - even this site is part of my CI pipelines!

Systems administration

Linux is my world! I also enjoy working with a lot of other server-related software: Virtualisation (KVM, Docker, Kubernetes), storage (ZFS, NFS), services (Nextcloud, Jellyfin, BookStack and many more) or management (Netdata, Ansible) are only some of my specializations!

Software engineering

I love to design systems: Starting by just the internal class diagrams of a server instance up to the whole API backend with distributed MicroServices.


You need a website or want to modify an existing one? Wordpress, Joomla and now Hugo - I worked with all of them. Or maybe you just want to redesign some static content?

Ceiling Light: B.K.Licht and Home Assistant

on April 8, 2022 15:21

Leadup Everything started as I bought the “LED Panel, Colour Temperature Fully Adjustable […]” by “B.K.Licht” off Amazon. It worked great with the also shipped remote control and it was only a little bit inconvenient to never have the remote when needed. It is a 15W LED panel with RGB/WW/CW and therefore 5 channels. I chose it because the pictures in the reviews indicated a modular power supply and also showed some minor information about the wattage and ratings.

The local power provider changes the electricity meter Please note, that after that timeframe some services may not work properly and therefore do not hesitate to contact me if any problem persists too long (not everything is monitored from my backend).
