If you're looking for a platform, I STRONGLY encourage you to look at either OpenDSA or Runestone, two open source interactive textbook platforms. I've been hacking on the latter this summer, porting it over to Runestone for a course I'm teaching (on Computational Thinking) (https://github.com/RealTimeWeb/runestone-flask https://github.com/RealTimeWeb/runestone-flask is my public facing copy to give you an idea, but it's not a full copy of my port). I'm very familiar with the development teams for both these platforms, and they're both very friendly and desirous of collaborations!
