Too Long; Didn't Read
Programmers and Software Developers can create and sell online courses on Teachable, Udemy, Thinkific, Podia, Skillshare and other platforms. Creating and selling online courses are the best thing a programmaker can do to earn money online, earn a side income, learn something valuable, and make an impact on peoples life. Teachable/Thinkific and Udemy are two of my favorite platforms, they're both intuitive and user-friendly. With Teachable and Thinkific you have more control over your pricing and the look and feel of your course, but you don't get a built-in audience. You can create a free course almost free of cost, all these days, all of these days.
