I’m looking for a mobile developer who can deliver a functional prototype of an ambulance-ordering app that runs natively on both iOS and Android. Core requirement • Seamless GPS tracking so that once a user books an ambulance, they can watch its live location and estimated arrival. Key flow I want to see working 1. User opens the app and sets pickup (and optionally destination) on a map. 2. The nearest available ambulance is assigned automatically. 3. The user sees real-time movement of the ambulance until pickup. 4. Basic booking history is stored locally so the user can review past requests. Scope for this phase – Clean, intuitive UI that follows platform guidelines. – Reliable location services using Google Maps SDK (or Apple MapKit on iOS). – Simple authentication (phone or email) just to let users save trips. – Lightweight admin placeholder where I can view active bookings and ambulance locations (web or in-app). Deliverables • iOS and Android source code, ready for TestFlight / Google Play internal testing. • A brief README explaining environment setup, key libraries, and how to generate the builds. • Short loom or screen-share video walking through the main flow. Tech stack is up to you—React Native, Flutter, Kotlin/Swift, or native combined—so long as performance and GPS accuracy are solid. Please outline: – Your chosen framework and why it suits this real-time tracking use case. – Any similar location-based apps you’ve shipped. – Estimated timeline for the prototype (I’m aiming for a few weeks, not months). I’ll be quick to answer questions and provide test accounts for mapping or push-notification services if needed. Let’s get users the help they need faster.
