Engineering a cross-platform mobile driver application paired with a centralized dispatcher portal featuring live GPS telemetry, digital proof-of-delivery signatures, and offline-first queue synchronization.
Drivers traversed remote routes with intermittent mobile coverage. When connectivity dropped, drivers were forced to use paper manifests, leading to delayed invoices and lost proof-of-delivery signatures.
Dispatchers at headquarters could not see real-time vehicle coordinates or delivery completion statuses, forcing customer service teams to field dozens of daily "where is my shipment" inquiry calls.
TheNexusLogic developed a local SQLite database directly on the mobile client. All route stops, signature captures, and barcode scans write immediately to the local device with atomic timestamps.
The moment cell connectivity is restored, an intelligent background sync service uploads accumulated telemetry packets to the central AWS server without draining vehicle battery or crashing the UI.
