I already have polished wireframes and visual designs; now I need those screens turned into fully functioning apps for both iOS and Android. The core scope is end-to-end development: coding the front-end exactly to spec, wiring it to a secure back-end (cloud or on-prem, whichever you recommend), and preparing both builds for App Store and Google Play submission—including test-flight or beta tracks. My priorities are: • Pixel-perfect adherence to the provided Figma/Sketch files • Smooth, native-feeling performance on recent iPhone and Android devices • Clean, well-documented code that another developer could pick up if needed • A staging environment where I can review features as they’re completed • Clear milestones for alpha, beta, and release candidates I’m comfortable with either native (Swift, Kotlin) or a mature cross-platform stack such as Flutter or React Native, as long as final UX matches the designs and meets store guidelines. If your proposal references similar dual-platform launches you’ve handled—particularly those that started from ready-made designs—it will help me gauge fit quickly. Let me know your preferred tech stack, estimated timeline to MVP, and any questions about the existing assets so we can get started right away.
