It'd be hard to say without more information. Third world country is a wide and shifting definition, and it's the most important aspect of your question. Couple of general points:
1. A large number of countries have agencies that will aggregate freelancers and take on large jobs. I'm not suggesting large players in the size of TCS or SAP, but smaller shops that hire out devs. It's a good place to start to get contacts into companies you'd like to work at, then move to a direct position there. Most countries make anti-poaching clauses practically unenforceable, especially if the candidate is the one approaching the company.
2. This is higher risk higher reward, but building micro-B2C/SaaS for a different market then launching on sites like Product hunt have the opportunity to bring in revenue. This is only if you're cut out for it.
Can't say much more without details, but I wish you luck in your search!
