Emigrate. You speak English, Portuguese and ... ? You've got tech skills, there are tech visas for a lot of developed countries. Spend < 10 years working abroad and pay off your loan and move back to Brazil with some wonderful life experience. Also, in a native English-speaking (British Isles, US, Canada, Oz and Kiwiland) country the second language is a total bonus a lot of time ... If you've got commitments that tie you to Brazil see if they can be loosened for a few years :)
You hang out on HN long enough someone is bound to offer you one, but you should probably fill out your profile some more (email address and name, minimally). But even if they don't reach out to you, there are job opportunities posted almost every day. If you have the skill (you're here... it stands to reason) and put in the effort, you could be on a plane in a few months.
