I need a developer who can take my PropTech concept and turn it into a polished, production-ready mobile app for both Android and iOS. The core of the product is a property-listing marketplace, so screens for browsing, viewing details, and saving favourites must feel seamless and fast. A robust search experience is vital: users should be able to filter listings by price, bedrooms, neighbourhood, amenities, and any other field I add later. The search results have to appear instantly, even with thousands of properties in the database. I already have basic wireframes and an API spec for property data. What I need now is someone who can: • Build the full frontend in a shared codebase (React Native or Flutter would keep maintenance simple, though I’m open to native Swift/Kotlin if you can justify it). • Integrate the existing REST endpoints and set up local caching for offline viewing. • Implement map view, push notifications, and social-style share links. • Publish the finished builds to the App Store and Google Play under my accounts, handling store-listing assets and compliance checks. Acceptance criteria: the app passes review on both stores, search filters return accurate results under one second, and the UI matches the Figma files within a 5 px tolerance. If you can hit those marks, let’s talk timelines and milestones.
