I am ready to kick off development of a music-centric mobile application that will run natively on both iOS and Android. The core idea is to give users an elegant, reliable way to enjoy music on the go; exact features (think playback, playlist creation, offline mode, user profiles, in-app purchases, social sharing, etc.) will be finalised together once we engage, but the overarching goal is a polished, engaging audio experience that feels right at home on each platform. Here is what I need from you: • Technical leadership on the best architecture for a dual-platform build—whether that is Flutter, React Native, Kotlin + Swift, or another proven stack. • End-to-end development: UI/UX design, frontend implementation, back-end/API integration, testing, and store deployment. • Clean, well-documented source code I can continue to maintain or hand to another team later. • Guidance on App Store and Google Play submission, including compliance with their latest audio-streaming and privacy requirements. Acceptance criteria will be a fully functional TestFlight/Play-Internal build that passes our agreed feature list, along with step-by-step deployment documentation. If you have shipped music or audio apps before, tell me about it when you respond and include links or package names so I can try them out. I am ready to move quickly once I find the right partner.
