I need an experienced software developer to build a mobile application that runs smoothly on both iOS and Android. The core goal is to deliver a single code-base solution—using Flutter, React Native, or another proven cross-platform framework—that can be compiled and published to the App Store and Google Play without major rework. Scope • Design a clean, intuitive UI that follows Apple Human Interface and Google Material guidelines. • Develop the complete app logic, API connections, and local data handling. • Configure platform-specific settings (notifications, permissions, icons, launch screens). • Provide test builds, gather my feedback, and iterate until we lock the MVP. • Prepare final release builds and hand over well-commented source code with setup instructions. What I will supply • Feature list and basic wireframes. • REST API documentation and access keys. • Branding assets (logo, color palette, fonts). Acceptance Criteria • App installs and launches without errors on current iOS and Android versions. • All stated features work as described in the spec. • Code passes linting and builds cleanly via command line. • Stores’ compliance checks are cleared or issues are documented with resolutions. If you have a portfolio of similar cross-platform projects, share the links so I can gauge fit quickly.

I’ve delivered cross-platform apps using Flutter and React Native that met app store requirements without major rewrites—most recently for a healthcare client who needed secure data sync and smooth UI on both iOS and Android. To ensure we hit Apple’s and Google’s design guidelines, I’ll start by aligning your wireframes with platform standards, then build out API integration and local data management for reliable performance. I’ll handle notification setup and permissions per platform, plus configure launch screens and icons based on your branding. Testing and feedback cycles are key, so I’ll provide builds regularly to gather input and adjust quickly. Before release, I’ll prepare clean, linted code and clear setup instructions to simplify your team’s handover. Could you share if any offline functionality or specific push notification features are required? Also, do you have preference between Flutter or React Native based on your team or existing infrastructure? I’m ready to review your wireframes and API docs and start turning your feature list into a polished, multi-platform app.
