John started out shipping Mac and iOS software, including Captain FTP and iSoftPhone, then moved into product leadership. He scaled a payment gateway from a handful of payment methods to more than 140, and led AI Dashcam, recognised with the 2024 IoT Evolution Product of the Year and a Gold Globee for customer excellence.

Caddora is where he builds his own products again, this time across the whole stack with AI: iOS and Mac apps, Supabase backends, on-device computer vision and the sites around them.

How the studio works

Every Caddora app is designed, built and shipped by John, with AI as a working partner across the whole stack: the Mac, iPhone and Android apps themselves, the backends they talk to, and the websites around them. A studio of one can now ship what used to take a team, and keep each app small enough to do one job well.

The apps share a few rules. They show what they will do before they do it: a cleaner measures before it deletes, and nothing moves until you approve. Work stays on your device wherever it can, so photos are analysed on the phone and translation works offline. And Folio Refresh, Cameleon and RefreshYourMac are each bought once, not rented by subscription.

The answers behind the apps are written up too, in the studio's how-to guides.
