I taught computer science and physics as both a teaching assistant and as an instructor in a university environment over the course of 8 years, and did very similar work industrially after that. I now make educational content for youtube, among other fun activities. I'm happy to tutor the above topics (physics, general science, or computer science, at more or less any level), either for pay, or in exchange for the topics listed (I want to learn to draw! I think having a tutor would really help me :) ). Until the current chaos is past, I'd prefer to do my teaching online.
