I’m ready to deploy a unified vehicle-tracking platform that feels effortless on every screen. The core requirement is live, second-by-second location data streaming into both a native Android and iOS app and a browser-based dashboard. As soon as a vehicle moves, I want its position updated without noticeable lag. On top of that live map, I expect three automatic alerts: when drivers exceed speed thresholds, when a vehicle is used outside authorised hours or zones, and when scheduled maintenance is due. Each alert should trigger push notifications in the mobile apps and pop-up or email options on the web dashboard. To give fleet managers fuller insight, I also need driver behaviour scores (harsh braking, rapid acceleration, cornering), fuel consumption trends, and basic on-board diagnostics health indicators displayed alongside the trip feed. Please build: • A responsive, password-protected web dashboard with real-time map, historical playback, and exportable reports • Companion Android and iOS apps mirroring the same data and alerts, complete with push notifications • Secure data flow from trackers (or a well-documented API endpoint if you prefer to ingest third-party GPS hardware data) into both front-ends • An admin area where I can set speed limits, geofences, maintenance schedules, and view driver-behaviour scoring rules Clean, well-commented code and concise setup instructions will be the final hand-off. If you have existing modules that shorten delivery time, feel free to leverage them as long as the user experience stays smooth on every platform.
