DeliverIt
Last-mile delivery that works offline.
DeliverIt is an offline-first delivery management platform for last-mile logistics operators. It gives drivers a mobile app that works without internet, optimises multi-stop routes automatically, and captures digital proof of delivery, while giving dispatchers a live web dashboard to monitor their entire fleet in real time. Built as a developer on the project.
The Problem We Solved
A regional logistics operator was running 50+ drivers across semi-urban delivery zones where mobile data coverage was inconsistent. Drivers were navigating with WhatsApp screenshots of addresses, marking deliveries as 'done' in a paper logbook, and calling the dispatcher when they got lost. Failed deliveries, where no one was home or the address was wrong, were running at 22%, and the operations team had no way to know until drivers returned to the depot at the end of the day. Re-delivery attempts were eating into margins.
What We Built
We built DeliverIt as an offline-first React Native app using SQLite as the local data store. Each driver's full delivery manifest, including addresses, contact numbers, delivery notes and route order, is downloaded at shift start. Route optimisation runs on-device using a modified nearest-neighbour algorithm against the Mapbox Directions API, recalculating if a delivery is skipped. Proof of delivery captures a photo and e-signature, stored locally and synced to AWS S3 via Supabase when connectivity returns. The dispatcher dashboard, a Next.js web app, receives live location pings via Firebase Cloud Messaging when drivers are online, showing each driver's position, completed stops, and failed attempts on a live map.
What We Achieved
38% reduction in failed deliveries within 60 days of launch
Full offline functionality, so drivers complete shifts with zero connectivity and sync on return
Route optimisation cutting average driving time per shift by 18%
Digital proof of delivery eliminating disputes with end customers
Dispatcher dashboard giving real-time visibility across 50+ drivers simultaneously
