I need an end-to-end order processing and delivery solution that runs smoothly on the web, Android, and iOS. The entire system will be used exclusively by admins and managers, so the interface must surface the information they need without clutter. Core workflow • Orders are created or imported into the system, then move through clear fulfilment stages. • Real-time order tracking shows current status, location data, and time stamps. • A user-management module lets me add, deactivate, or edit staff profiles and set role-based permissions. • A built-in analytics area should visualise daily volumes, delivery times, and performance trends that can be filtered by date range, team, or individual driver. Tech expectations A single, secure API should power all three front-ends to keep data in sync. I’m comfortable with React (web) plus React Native or Flutter for the mobile apps, but I’m open to other modern stacks if you can justify the choice. Push notifications, GPS integration, and offline handling for spotty connections are essential. Clean architecture, well-commented code, and a hand-off session are part of the job. Deliverables • Responsive web dashboard • Native or cross-platform Android and iOS apps published to TestFlight / internal track • REST or GraphQL backend with documentation • Source code in a private repository and a brief deployment guide Acceptance is based on successful end-to-end tests: creating an order in the dashboard, tracking it on both mobile platforms, updating status, and viewing aggregated metrics without errors. If this sounds like a build you can own from start to finish, let’s talk timelines and milestones.
