I am in São Paulo

I never got full time job offer, only contracts, some that were joblike (ie: company treated me as actual contractor but expected me to be present 9-5 every day in the office).

When I was fresh out of college I did got some offers for part time work, but with wage so small it wouldn't cover any of my costs at all (for example wages were smaller than my monthly debt repayments of student debt alone).

It sounds like you have good programming experience and can write decent English. I would look for remote work with a North American or European startup, send them your GitHub account and recent work. That would be better than trying to find a local opportunity
