I need a skilled frontend developer to craft the UI layer of a brand-new mobile app that must run smoothly on both iOS and Android. The visual language should strictly follow Material Design so the screens feel clean, familiar, and consistent across devices. The first functional milestone is solid user authentication: email/-password sign-up, secure login, password reset, and graceful error handling. Once the authentication flow is in place, I’ll expand the scope to other features such as push notifications and in-app purchases, so clean, modular code is important. Deliverables • Complete set of Material-styled screens and reusable components. • Fully wired authentication flow calling my existing backend API. • Build files or instructions so I can compile the app in Xcode and Android Studio. Acceptance criteria • UI matches approved Material Design mock-ups pixel-perfectly. • Authentication screens work flawlessly on the latest iOS and Android releases. • Code is lint-clean, well-commented, and pushed to my private Git repository. If you’ve delivered cross-platform UIs before and enjoy sweating the details of Material Design, I’d love to see your portfolio and get started.
