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.

Webdesign

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?
