A comparison shopping app for (legal) digital movies, so I can just go to the app to find the best prices rather than the one app and six web pages that I go to now. Between being laid off then having to go on disability for a year just after that (2019 was fun), I need some additional skills in the current job market. It just so happens that this project covers all the bases: new language (Go, which I really like), cloud computing, cloud-native architecture (containers and much more), and mobile app development. I really hope I get a job before I'm finished but this is something I'm motivated to work on and will give me some experience that the next job may or may not.
