iOS & React Native developer — Bucharest, Romania.
I design, build and ship apps end to end, on my own: native iOS and macOS in Swift and SwiftUI, cross-platform in React Native and Expo, and the backends when a project needs one. I lean on coding agents — mostly Claude Code and OpenCode — to move faster across the whole stack. Six apps on the App Store and Google Play, plus a few open-source libraries for the gaps I kept hitting along the way.
🟢 Available for freelance and contract work — remote or Bucharest.
Native Apple capabilities for React Native and Expo, built with the Expo Modules API.
| Package | What it does |
|---|---|
| react-native-icloud-kit · npm | CloudKit and NSUbiquitousKeyValueStore for React Native — save, query and batch CKRecords, key-value sync, and iCloud entitlements via an Expo config plugin. |
| react-native-apple-runtime · npm | Authoritative Apple runtime detection — tell an iOS app running on macOS ("Designed for iPad") apart from a real iPad, and read the UIUserInterfaceIdiom. Things Platform and expo-device can't answer. |
| react-native-apple-key-commands · npm | Dynamic hardware-keyboard shortcuts (UIKeyCommand) — register key commands from JavaScript and get an event back when one fires. |
