Dedent Tabs

Hobby - June 2019

The package dmnd/dedent is pretty awesome, but it is lacking support for tab indentation and is not maintained anymore. For that reason I continued maintaining it and published dedent-tabs which is now downloaded over 10.000x per Week.

Slate.JS Sorting Task Plugin

University - February 2019

As part of the course "Web Development with Web Frameworks" we have developed a Slate.JS plugin, which will transfer the educational concept of sorting tasks into the digital world. We focused our development on a super simple, intuitive design for students and teachers. In addition, we focused on writing really clean code to ensure a smooth transition to the core editor development team.

Stepcraft CNC GRBL Controler

Hobby - May 2016

Our school got an awesome Stepcraft CNC but the software was horrible. Sadly the used controller was proprietary. The solution: I wired up an Arduino (with a lot of reverse engineering), uploaded some software. We can now use any public available GRBL Software like the one provided by easel.com.
