I need a developer who can create a polished mobile service application that mirrors the professional tools used in phone-repair shops. The app must run smoothly on both iOS and Android from a single code-base so day-to-day updates remain efficient. Core requirements • Build two companion apps (or a single cross-platform build) that compile natively for iOS and Android. • Focus the user experience on the Customer role—log in, view or initiate a service request, and interact with repair-shop information. • Match the look-and-feel of leading repair-shop software: clean dashboards, quick search, and clear status indicators. • Supply the full source code, build instructions, and a short user guide that lets staff upload the binaries to App Store and Google Play without re-coding. Technology is flexible, but I prefer a mainstream cross-platform framework (Flutter, React Native, or similar) connected to a REST or GraphQL back end so future roles—Technicians and Store Managers—can be layered in easily. I will provide reference screenshots of an existing shop solution once we start. Please outline: 1. Your recommended tech stack. 2. An estimated timeline to reach a functional prototype and final release. 3. Any prior work that shows comparable cross-platform apps you have built. Looking forward to collaborating on a reliable, maintainable tool that elevates the customer experience in our repair shops. unlcok frp icloud
