Question

IT education

Brother wants to go full stack. A mathematician and an engineer by education, I have long wanted to go into coding, but there was no time, and now I have. I tried to throw something like a course, where to start and where to move, with the help of which books (Russian-language) and resources to study, but something is hard for me with this, everything that turns out to give birth one way or another is not from scratch ...
I would be grateful for help in compiling the course "entering IT from scratch or how to become a coder"
