I am an instructor of robotics (LEGO Mindstorms EV3 sets) in local elementary school, giving computer classes in local high school, providing IT support and website assistance and also studying Cyber-Physical systems engineering.
I have been doing a lot of webpages on Joomla! and it seemed fair enough to put some of my knowledge about Joomla! and others out on the web.
Hope you'll find something useful.
