The Challenge & Engineering Friction
A regional courier fleet dispatching 3,000+ parcels daily was trapped in legacy paper manifests and fragmented phone calls. Drivers experienced severe delivery delays due to suboptimal stop sequences, lost parcels in transit with no verifiable chain of custody, and suffered from constant app crashes whenever delivery vehicles entered cellular dead zones (underground parking and rural estates).
Customer support was overwhelmed with "Where is my parcel?" complaints because dispatchers lacked real-time visibility into driver locations.
The Technical Solution & Architecture
ARdevlopers built a unified digital logistics ecosystem consisting of a native-performance React Native mobile app for couriers and an administrative web console for fleet dispatchers. We engineered an offline-first SQLite cache on the driver app that queues barcode scans, photo uploads, and customer digital signatures locally, syncing them in batch via background jobs the moment network connectivity is re-established.
The mobile app incorporates Google Maps Directions API with dynamic waypoint reordering, while dispatchers monitor live vehicle telemetry on an interactive web map with geofence arrival triggers.
Core Architectural Decisions
Offline-First Client Sync
WatermelonDB / SQLite local mobile database storing stop manifests with background queue synchronization.
Real-Time Fleet Socket
