If I were you (which I'm not), I'd sign-up for a coding boot camp - especially if you used to do it 10-15 years ago, a refresher would be good
But before you sign-up for a boot camp, scope out the types of companies you'd like to work for and what their junior developer jobs list as requirements
Not much point in taking a Python boot camp if the companies you want to work for are using Scala :)
Good luck!
