I’m looking to turn my concept into a fully-functioning mobile application that runs natively on both iOS and Android. Because the core feature set is still being finalised, I need a developer who is comfortable shaping requirements with me, recommending the right cross-platform framework (React Native, Flutter, Kotlin Multiplatform, or a similar toolset), and then carrying the build right through to App Store and Google Play submission. What matters most to me is a smooth, consistent user experience across devices, clean and well-documented code, and a development process that allows for iterative feedback. You’ll handle UI/UX implementation, core functionality, testing, and store-ready packaging; I’ll provide prompt responses and clear decisions at every milestone. If you have a solid track record shipping cross-platform apps, can walk me through best practices for security and user authentication options, and are comfortable setting up CI/CD for future updates, I’d love to hear how you’d approach the project and an estimated timeline for each stage.
