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.
