One codebase, iOS and Android, without the app feeling like a compromise on either one. Flutter is where I've spent most of my professional work, including leading Buy/Sell/Swap and Wallet features at a crypto fintech, where the money has to move correctly every time.

I've also shipped multiple Flutter apps, including some of my own, to the App Store: Hubbit, an AI habit tracker; and Haven Guide, an AI sermon tool. Both with full RevenueCat IAP, Firestore security rules, and Shorebird OTA patching, so bug fixes ship in minutes instead of waiting on App Review.
