For my journey, which is still starting (I am just now comfortable to apply for jobs, gotten an interview, but not employed yet), Harvard's CS50x was an amazing "Bridge gapper", but outside of that it's been courses on things such as Udemy, LinkedinLearning as of recently, and Youtube. I haven't gotten too far into it, but there is this github repo created to supplement the knowledge learned in a computer science degree titled Open Source Society University as well.
