“I've been working with Robin for the past month on learning CS fundamentals to support the work I'm doing in developer marketing. He has been incredibly helpful and easy to work with. I really appreciate his style of teaching -- he uses various visual aids, assignments, and pop quizzes to demonstrate and reinforce abstract concepts. He's also personable and professional. Highly recommend him if you're looking for this sort of instruction!“
