About this gig

Does your app crash or fail to build after an SDK update? Are outdated dependencies stopping you from releasing updates? I can help by upgrading your React Native or Flutter app to the latest stable version and fixing all related issues.


I will:


  • Upgrade your React Native or Flutter project to the latest SDK
  • Update Gradle, Cocoapods, and third-party dependencies
  • Fix build errors and dependency conflicts
  • Ensure compatibility across iOS and Android
  • Deliver fully tested release builds ready for App Store and Play Store


I have 10+ years of mobile development experience and have upgraded many production apps without losing functionality. I handled full SDK and package upgrades, resolved breaking changes, and delivered stable builds on time.


Why choose me?

  • Smooth upgrade with zero data loss
  • Tested builds for iOS and Android
  • Clear documentation of changes made
  • Expertise in React Native, Flutter, Expo, Swift, and Kotlin
