I’m building a consumer-to-consumer mobile application and need it released simultaneously on iOS and Android. The concept enables everyday users to connect directly with one another to exchange goods or services, so the entire flow—from onboarding to closing a transaction—must feel effortless and secure on both platforms. At this stage I have a high-level product vision, wireframe sketches, and a basic brand style guide. I’d like a developer (or small team) who can turn these assets into a polished, production-ready app, advise on technical architecture, and handle store publication for Apple App Store and Google Play. Key expectations • Native or high-performance cross-platform codebase that fully respects each platform’s design conventions • Clean, well-documented source code pushed to a private Git repo throughout the build • Proactive guidance on choosing and integrating core C2C features such as user profiles, in-app messaging, and secure payment handling (I have not locked these down yet, so your expertise will shape the final stack) • Basic analytics setup so I can track user acquisition and engagement from day one • Post-launch support window for bug fixes and minor tweaks Acceptance criteria • Both apps pass App Store and Play Console review without rejection • Core user journey—from account creation to completing a transaction—tests successfully on recent iOS and Android devices • No critical or high-severity issues in the first two weeks after launch If this sounds like a build you can own end-to-end, please tell me a bit about your preferred tech stack for dual-platform delivery and share a recent C2C or marketplace project that proves your approach.
