I need a skilled developer to turn my concept into a polished cross-platform mobile application that runs seamlessly on both iOS and Android from a single code-base. Whether you prefer Flutter, React Native, or another modern framework, I’m open so long as performance and maintainability stay front-of-mind. Here’s the flow I have in mind: • Collaborate on refining core features and selecting the best cross-platform tech stack. • Produce wireframes or a clickable prototype to lock down the user journey. • Build, test, and iterate through short sprints, delivering TestFlight and APK/AAB builds each cycle. • Final hand-off will include the complete source code in a Git repository, build scripts, and concise deployment documentation. Quality, clear communication, and clean architecture are more important to me than the specific toolset, so feel free to suggest what you do best. If you have shipped similar cross-platform apps, a brief note on the toughest challenge you solved and a link to a live build or store listing will help me gauge fit. Once we agree on scope and milestones, I’m ready to move quickly. I look forward to hearing how you’d approach this build.
