I help writing the official documentation of GeoGebra and maintain the Italian version of the site and the software. GeoGebra Authoring Lead. Paper planes pilot. Maths textbooks writer and curricula planner, I love computers and technology, mathematics, teaching, chocolate and athletics. I hate self-centered people, who acts high and mighty, melons and turnips. My mantra is "Together is better" - sharing knowledge is the best way to learn and teach. Despite my geekiness and being (sometimes too much) rational, a smile on my son's face is enough to make my day :) You can find my Ggb tutorials here https://www.youtube.com/@GgbEasy They are in Italian, but isn’t math (and Ggb) a universal language?
