Back when I was in the Air Force, I hated the UX for referencing Air Force publications on mobile. So I created an iOS app called AFI Explorer [0] which has continued to get hundreds of downloads every month for the past 5 years.
Since I’ve been shifting more towards platform engineering work in my career, the best reward abut this side hustle isn’t the financial benefit, but is the opportunity to stay grounded in software dev. I love seeing the changing APIs each year with the new iOS updates. And the seasonal approach to doing updates is always fun too.
