Cross-Platform Productivity App Development

I am building a productivity-focused mobile application that must run natively on both iOS and Android. The core concept and screen-flow are already sketched; what I need now is a skilled coder who can turn those ideas into a reliable, polished product.

Cross-platform frameworks such as Flutter or React Native appeal to me for their single code-base advantage, but I am open to a Swift / Kotlin duo if you can show clear benefits in performance or long-term maintainability. Whichever route we take, the finished app should feel fully native, sync data seamlessly, and be ready for distribution in the App Store and Google Play.

To keep the project on track, I will provide the wireframes, feature list, and API endpoints (if we decide on a cloud-backed architecture). Clear, commented code and consistent UI behaviour across devices are essential acceptance criteria.

Deliverables
• Complete source code in a Git repository
• Testable builds for iOS and Android
• Brief setup & deployment guide
• One revision cycle after initial hand-off to iron out edge cases
