Marcin is deeply knowledgable. No question is to simple or too intricate. Great overview of all the necessary topics relating to coroutines, flows, and more. Marcin has good examples and metaphors. He backs this up with detailed code examples, experiments, live coding and some practical exercises and katas for the team. A very valuable training for our whole team.
