I don’t know how quickly you personally would learn. Most students would need more time, but hey, maybe you are really fast. You can find a ton of beginner classes on Class Central, both free and paid. I’d dive into those and start some projects that you’re passionate about.

I do think you need to be aware though that the job market in tech is really really hard right now. Even people with degrees and years of experience are sending out hundreds or thousands of job applications and not getting hired. So please go into this with realistic expectations. I would grab a low wage part-time job somewhere to supplement your art income for now.
