Field Service Management App
Offline-First Job Tracking, GPS Routing & Live Manager Dashboard
Project Overview
A facilities management company had technicians arriving at jobs without the right parts, dispatchers unable to see real-time location, and paper job sheets taking 2 days to process. Half their job sites were underground or in signal-dead buildings. They needed a mobile-first system that worked everywhere.
The Challenges
- 1
Offline-first architecture was non-negotiable — many sites have zero connectivity
- 2
GPS accuracy in dense urban environments with tall building interference
- 3
Photo uploads with high file sizes over poor connections on job completion
- 4
Conflict resolution when multiple offline changes sync simultaneously
Our Approach
We built a React Native app using WatermelonDB for offline-first local storage. Native GPS with background tracking handles location even underground. A photo compression and background upload queue handles large files over poor connections. All offline changes reconcile automatically against the server when connectivity restores.
Key Features & Metrics
Fully offline-capable: complete job management with zero connectivity required
GPS route optimisation reducing average technician drive time by 18%
Timestamped photo documentation required at each step of every job
Background sync: all offline changes reconcile automatically when signal restores
Live manager dashboard showing technician locations and job status on a map
First-time job completion rate improved from 71% to 89%
Results & Business Outcome
First-time job completion rate improved from 71% to 89% — correct parts on first visit. Paper processing eliminated entirely. Dispatch coordination time reduced by 38%.
A field workforce is only as efficient as the tools in their pocket. Building offline-first is the difference between a tool that helps and one that gets left in the van.
