What do I need to know to be hired as a junior back-end web developer?

I just turned 30, quit my job as I want to pursue some other adventures in my life. I'm from one of the poorest country in the world, Madagascar, but I've been living and working in France for the last 12 years. I came to study and stayed when got offered a job as an accountant. The thing is, I miss my country and going on vacation is not enough anymore, plus my parents are getting older, I'd rather be with them. I have enough savings to live there for a long time, without working thanks to exchange rate, but I'd rather not take more than a year off. After reflecting on what I like, and what I could do (given the pandemic crisis going on), programming for a living seems like the way to go. I can hack some quick and dirty script here and there but that's it. Now I want to do it rigorously, and have a already made a plan for that (link at the bottom). My end goal, if things go the way its planned is to find a job and earning between 600 and 900 dollars a month.

- I know have to have some projects built so I can stand out. But for now I'm thinking of what I could do that is meaningful enough and not just a random stuff that has been done a thousand times, by following a YouTube tutorial.

- Beside my plan, what do I need to know to get hired? (by the way if you know some good java open source codebase I could study, please link them)

- How low/high are my chance of getting hired by a foreign company while living there? Anyone that was in the same situation please reah out.

- Freelancing, creating a business are other options, so if you have any tips on doing that don't hesitate.

I speak french, and I like to think my English is ok (tell me otherwise so I'll add that to my study plan), so communication should not be a problem. As for internet, believe it of not you can get what's advertised as "fiber" for 55 bucks a month, 100Mbps up/down on paper.
