I pioneered in creating unique math teaching videos and visual math programs to make mathematics more attractive to students. My Elearning platform “Matheretter” was rated the best German elearning platform for mathematics in 2018/2019. I also founded the biggest German mathematics forum.
Developed "Assistenzrechner" - a set of assistance calculators with visualisations, mainly using Three.js and EaselJS. Feel free to try: Geoservant 3D (in English).
