Hey HN! I recently published a free tutorial on Boot.dev (my side project). It's not a FULL walkthrough, the purpose of "projects" on Boot.dev are to be "semi guided", but there is solution code at every step of the way in case you get stuck.
All the projects are completely free on Boot.dev, you don't even need to sign in. The courses are free to read, but in order to pass off assignments you need to login, and in some cases become a patron.
Anyhow, this project is a part of the "backend learning path": https://boot.dev/tracks/computer-science
I'd be really stoked to hear any and all feedback :) Hope you enjoy the project
