"I am a life-long professional mathematician (Math PhD), computer-scientist, expert chess player, and an educator. I have been teaching and tutoring mathematics since my youth, leading a math circle, teaching algebra and trigonometry in high school, and tutoring mathematics one-on-one.

I also had spent more than a decade educating adult professionals (engineers) in various aspects of computer science (both theoretical and practical) and mathematics.
