Try Uber EATS or DoorDash. Uber EATS offers part-time work that’s similar to driving for Uber or Lyft. Instead of picking up passengers, however, you will pick up food orders and deliver them in your area. Pay works similarly, letting you earn a per-job rate plus tips. Door Dash works similarly, letting consumers order food from restaurants and connecting drivers to pick up and drop off their meals.

Now, I know what you’re thinking. Most of the software and apps you use on a regular basis are made by massive companies or established development studios. Well, yes.

In fact, independent developers made $20 billion in the App Store in 2016 alone.

Amazon will have you work on micro-projects that require some sort of human interaction. Tasks can include translating a paragraph into English (or another language), rating the search results for certain keywords, or reworking an article. The tasks are simple, and you will be paid a small amount to complete each. But if you do enough tasks quickly, you can make a respectable amount of money.
