This project covers the full design and development cycle of a professional business app centred on three pillars: robust permission processing, rich location services, and streamlined data collection/processing. Permission processing must include: • User authentication • Role-based access control (RBAC) • Clear data-sharing consent flows that users can review and update at any time Location services must deliver: • Real-time tracking with minimal latency • Geofencing that triggers business logic on entry/exit events • Contextual, location-based notifications that respect the user’s consent settings I need an intuitive interface backed by a reliable cloud-ready backend. Expect to architect the database, implement the API layer, build cross-platform mobile clients, and provide concise technical documentation so future maintenance is effortless. Acceptance criteria will be a fully functional build passing end-to-end tests for every permission scenario and all three location features, plus documented source code in a version-controlled repository.
