Career change at 30, or after, is very possible. I've had several big ones over the years and am just going through another transition at the tender age of 55!

Career change at 30, or after, is very possible. I've had several big ones over the years and am just going through another transition at the tender age of 55! You are probably about where my son is now, although he's a few years younger than you. He is moving from electronics / HVAC into a career in web design/development and is already getting decent gigs on a freelance basis and has had several interviews for jobs that pay what I could only have dreamed of as a struggling FE lecturer when I was his age. You could follow his Instagram at 'countryside.coder' and maybe pick up some tips - he has various friends/followers that are doing the same thing. Getting into the Google scholarship program has been a big help to him. In terms of skills: the usual - Python, JavaScript, HTML, CSS. He is now learning PHP as he's picking up work that requires it (Wordpress, Drupal). Good luck to you!
