I’m building a mobile marketplace where people can buy or sell real-estate. The first release needs to run smoothly on both iOS and Android, so feel free to suggest React Native, Flutter, or any other framework you trust for true cross-platform builds. Core scope for this phase • Property listings – users must be able to upload photos, set price, add location and key details, then publish the listing. • User profiles – buyers and sellers should manage their own dashboards, saved searches, and listed properties. Deliver a functional prototype with a clean, intuitive UI, basic authentication, and stubbed backend endpoints ready for future features such as in-app messaging. Please share links to past work on comparable apps, noting any store URLs, screenshots, or code samples you’re allowed to show. A concise outline of the tech stack and timeline will help me evaluate fit.
