I’m looking for a seasoned professional—someone with at least 8-10 years of hands-on experience who has taken full ownership of product design and development before—to shape both the user experience and the codebase of a new mobile product. The task covers the complete journey from first wireframe to store-ready build, and it must run smoothly on both iOS and Android. Because I have a hard deadline, everything needs to land inside a one-month window. Here’s how I picture the flow: • Discover & Define You’ll dive into the product vision with me, map core user journeys, and validate them with quick, clickable prototypes. • Design & Prototype High-fidelity screens, micro-interactions, and a living design system created in Figma (or the tool you prefer), followed by an interactive prototype for rapid feedback. • Build & Integrate A clean, well-architected mobile codebase—native Swift/SwiftUI and Kotlin, or a robust cross-platform stack such as React Native or Flutter—integrated with the existing backend through REST/GraphQL endpoints. • Test & Polish Unit tests, lightweight UI automation, and TestFlight/Play Store beta releases to catch edge cases before launch. Acceptance criteria – Consistent look and feel across iOS and Android – Zero critical crashes in beta builds – App passes App Store & Play Store submission reviews on first attempt – All source files, design assets, and documented setup steps are handed over on sign-off If you thrive on working independently, enjoy end-to-end ownership, and can deliver a polished dual-platform app inside the next four weeks, let’s get started.

I understand the urgency and the full scope you need covered—from user flows and design to clean code and app store approval. I’ve helped a startup build a similar mobile product within a tight deadline, owning everything from sketches to the launch-ready app on iOS and Android. We used Flutter for quick yet solid cross-platform performance, paired with fast iterations on interactive prototypes. To speed validation, I suggest early clickable flows that test key journeys with real users. For development, would you prefer fully native or cross-platform? Also, any specific backend constraints I should know about for smoother API integration? With careful planning and regular check-ins, I can deliver a polished, crash-free app that meets store requirements on the first try. I’ll also provide all design files, code, and clear setup documentation so you have full control after delivery. Ready to start the discovery and move fast to hit your one-month deadline.

Full code-and-design builds with store delivery mean nothing ships late unless the code and Figma both match from week one. I’ve handled 3 end-to-end Flutter and React Native apps for clients needing exactly this: one source for both stores, workflow locked tight, with handover docs prepped at the end. For your timeline, I’d use Flutter for a single shared codebase (iOS/Android), Figma for screens and live prototypes, and direct backend integration over REST or GraphQL per your API. I build testable handoffs and prepare TestFlight/Play Store betas after unit/UI coverage. How stable is your backend—REST specs finalized, or do endpoints change? That sets the integration/testing focus. If you want your first dev build mapped out this week, reply and we’ll scope core journeys now. Pradeep
