Software development

C/C++ (♥), Python, PHP, HTML, CSS, JS, QBASIC, Java or Kotlin. I speak them all! My favourite rendering APIs? Vulkan, OpenGL and GLSL. Librarys? Here my most frequently used ones: Python Flask, Vulkan SDK, libCurl, GLUT, GLAD, SDL2 and GTK+.

Development operations

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

Software engineering

I love to design systems: Starting by just the internal class diagrams of a server instance up to the whole backend API and frontend representation.

Systems administration

Linux is my world - therefore my love to the LAMP stack! I also enjoy working with a lot of other server-related software: Virtualisation (KVM, Docker (Swarm)), storage (ZFS), serving (miniDLNA, Nextcloud) or management (Netdata, Ansible) are only some of my expertises!


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…


You need an intuitive and unique interface design for your next project? Whether you work with a C++ rendering pipeline or just need some JS with CSS - I’m here to help you!

Prusa Mini+ WiFi and virtual USB

on September 9, 2021 16:02

What? The Prusa Mini+ has a problem: It has no WiFi. Also the software does not support any wifi module until now - that feature is planned, but not implemented. Additionally the web interface is, let’s say, not really working, as the printer struggles with serving the static contents (like .css and .js), which are required to render the site. This issue is also known since release 4.3.0 but also not resolved (#1285).
