The nice thing about being 30+ is you’ve probably got the funds for a web development or data engineering bootcamp. A bootcamp will help you learn fast and build a portfolio. But it is like a part-time job while you’re doing it, so there is a big time commitment. They also help you find a job when you’re done.
If I were starting today that’s how I’d do it. Disclaimer: I mentor for a bootcamp
As for other advice besides how to go about doing it, I think everyone else in the thread has covered it.
Oh, but you might want to learn a little on your own first to make sure it’s what you really want to do before you spend money learning it.
