About this Gig

Need a bug fixed, a new feature added or an API connected in your mobile app? I can help, whatever your app is built with.


I am a mobile developer with my own apps live on the App Store: So Tai San (asset tracker with charts and encrypted local storage) and Washoku (Japanese recipe app). I work on mobile apps full time.


Tech I work with:

- Flutter / Dart

- React Native (JavaScript / TypeScript)

- Android native: Kotlin, Jetpack Compose

- iOS native: Swift, SwiftUI


What I can do:

- Fix crashes, layout issues, state and navigation bugs

- Add new screens and features

- Connect REST APIs or Firebase (Auth, Firestore, push notifications)

- Upgrade SDKs and packages, fix iOS / Android build errors

- Test on both iOS and Android


What I need from you:

- Your source code (Git repo or zip)

- A clear description of the bug or feature, with screenshots or a screen recording if possible


Please message me before ordering so I can check the scope and give an honest estimate. I reply by chat in English.
