This assignment is to transform an already-defined product flow into a fully functional fintech mobile app built with Flutter and Dart, released simultaneously on iOS and Android. I will provide the back-end endpoints, product requirements, and brand assets; your job is to turn them into a clean, maintainable codebase that meets store-ready quality. Core expectations • Design and implement a modern, responsive UI that feels at home on both platforms. • Wire up secure login, encrypted local storage, and any compliance checks needed for handling financial data. • Integrate the REST / GraphQL services I supply for accounts, transactions, and real-time notifications. • Configure push notifications, analytics, and crash reporting. • Supply TestFlight and Google Play testing builds, final store packages, complete source code, and a concise hand-off guide. Please focus your proposal on relevant experience—especially past Flutter apps and any work involving payments, banking APIs, or data security—as this will be the main factor in selection. We will define clear milestones for prototype, beta, and final release before coding begins, and I keep communication quick and straightforward so we can move efficiently from idea to launch.
