It’s great to see you scratching your own itch as a developer, and opening up the same tools for other devs. Almost all learning platforms were built with generic tools (like video or text tutorials), built by non-engineers.
I can see this approach scale beyond just tutorials: at Uber, we had an in-house interactive platform called codelabs we used for onboarding for new systems. It was dead simple to use and engineers created a lot more helpful materials that were easier to understand. Slip reminds me of this approach as well.
Best of luck!
