Just some free tutorial videos and content on what I am interested in. I was asked about my motivation: in my opinion education is a right, not a privilege. Therefore, everything I do in this field I try to do it accessible, adaptive and free. That's my motivation :D I hope you can use this. I am also grateful for all the free content a lot of wonderful people have created. I have learned a lot from them, I want also to help and give something back.
