ASCENDED ABOVE THE CLOUDS
Matt// startup founder
The experience with Lemon.io has been fantastic. The interview process has been good, the caliber of people – excellent and integration has been very smooth.
The Challenge
Dutch Goat needed a cross-platform mobile app for their fleet management business — drivers needed real-time route optimization, managers needed live vehicle tracking, and the back office needed automated compliance reporting.
Their existing web-only solution was unusable in the field, and drivers were resorting to paper logs.
What We Built
React Native Mobile App
A single codebase powering both iOS and Android:
- Real-time GPS tracking — live vehicle positions with geofencing alerts
- Route optimization — AI-powered route planning reducing fuel costs by 18%
- Digital logbook — automated Hours of Service (HOS) compliance
- Push notifications — instant alerts for route changes, maintenance, and compliance deadlines
- Offline mode — full functionality in areas with no cell coverage, with automatic sync
Fleet Management Dashboard
A React web dashboard for managers:
- Live fleet map — real-time positions of all vehicles with status indicators
- Driver performance — scorecards based on speed, braking, fuel efficiency
- Maintenance scheduling — predictive alerts based on mileage and usage patterns
- Compliance reporting — one-click DOT compliance report generation
Backend Infrastructure
- Real-time WebSocket connections for live tracking
- Microservices architecture handling 10K+ location updates/minute
- Integration with Samsara and Geotab telematics hardware
Tech Stack
- Mobile: React Native, TypeScript, MapboxGL
- Frontend: React, TypeScript, Leaflet
- Backend: Node.js, NestJS, WebSockets
- Database: PostgreSQL with PostGIS, Redis, TimescaleDB
- Infrastructure: AWS, ECS, IoT Core
Results
| Metric | Before | After |
|---|---|---|
| Driver compliance rate | 72% | 98% |
| Route planning time | 45 min/day | Automated |
| Fuel costs | Baseline | -18% reduction |
| App Store rating | — | 4.7 stars |
The app now manages 500+ vehicles across 3 states with 99.8% uptime.
