UI. User interface. Html css JavaScript. W3schools.com . You get instant visual feedback so it's a little easier to self teach. once you get a basic idea of a web page then read about how to use react js. Finally sign up for a coding boot camp. A cheap one don't spend 40k.

There is also English teaching if you already have a 4 year degree. It can be in anything. There is even a mostly free online university and companies will take that degree and allow you to teach English online.

That's all I got. Maybe some call center jobs.
