Ask HN: Udemy courses you recommend?

I'd recommend courses by Stephen Grider (https://www.udemy.com/user/sgslo/). I've been through some of his courses (React/React Native, Phoenix Elixir, Solidity). And all of them were very well documented, focused and accurate. Great stuff!

Not just on Udemy, but for MOOCs in general: https://news.ycombinator.com/item?id=16745042

Anything by Peter Dalmaris such as https://www.udemy.com/arduino-sbs-17gs/

I have two that I really liked Ruby by Boris and Advance CSS3 by Jonas
