Last-Mile Distribution Architecture
Delivery logistics systems need to process live driver location inputs, optimize drop sequences, and record digital proof of delivery. We use geolocation libraries and Node.js event streams (WebSockets) to handle live tracking updates from mobile devices.
Route Optimization Engine
Given 50 packages and 3 drivers, how do you split the load? We integrate with routing APIs (like Google OR-Tools or Mapbox) to solve the Traveling Salesperson Problem, clustering deliveries geographically and generating sequenced manifests for each driver.
const route = await mapboxClient.getOptimization({
profile: 'driving',
waypoints: deliveryCoordinates,
source: 'first',
destination: 'last'
});Digital Proof of Delivery (ePOD)
When a driver drops off a package, the mobile app captures a signature and a photo. These assets are immediately uploaded to an AWS S3 bucket, and the secure URLs are appended to the delivery record in the database, triggering a final delivery email to the customer.
