    Very nice solution. I have an idea:
    Why dont you go live and attempt problems with viewers?

      he has online classes. u can check momentumlearning.org for the olympiad courses.
      but olympiads are hard. very few people can actually solve them in a live setting and not look at the solution.
      if he tried about 99% of the stream would be him muttering to himself.
