I am fortunate to get to write software using tools I love and the opportunity to teach through TestDriven.io. It's all possible due to the countless hours invested by others into open source. These volunteers rarely receive praise or thanks and only a lucky few are able to monetize their work. And while many startups and large companies have built their platforms on open source, few ever give back.
While I am a longtime committer to open source, I know I can do more. So, I, along with a few other TestDriven.io authors, will be donating at least 10% of the profits from our FastAPI, FastAPI Celery, and Flask Web Development courses to the software that enables it. This is a first step toward a longer effort by TestDriven.io to support a sustainable open source model for our industry. This page will track my contributions and, I hope, inspire others to donate to open source as well.
