ACE

What it is

ACE is a social app I built for a client that lets people tell the person closest to them how they are doing without writing a word. Four signals (I'm Good, Need Space, Overwhelmed, Check On Me) live in an iMessage extension, so sending one is as quick as sending a sticker, and the same signals work from the app, Shortcuts and the Action Button through App Intents. Behind it is a Firebase backend I designed from scratch: Sign in with Apple accounts, pairing between two people, push delivery through APNs, App Check on every call, and account deletion that cleans up every device. Delivered in milestones, from the backend foundation to the App Store release.
