Group 42 (G42) is a UAE-based AI and cloud-computing company. 7Code partnered with G42 to build ESTS, an IoT fleet-tracking and smart-buildings platform deployed at EXPO 2020 Dubai, covering real-time vehicle location, geofence rule enforcement, custom event detection (overspeeding, loitering, geofence breach), trip playback, and dashboards for security and access teams. The stack: a custom device TCP server feeding a Node.js + React Native dashboard with Material-UI. Eighteen months of focused build plus six months of production maintenance.
Real-time, large-scale fleet tracking for a six-month global event with 200+ partners.
EXPO 2020 Dubai needed centralised, real-time visibility across vehicle fleets covering security, logistics, and visitor transport. Devices reported over a custom TCP protocol; events had to be processed, geofenced, and escalated within seconds; the dashboard had to remain responsive under heavy concurrent load.
- Custom device TCP protocol with streaming telemetry
- Real-time geofence rule evaluation across many vehicles
- Trip playback and historical event reconstruction
- Six-month event window with no tolerance for downtime
TCP ingestion, rule-based geofencing, and a real-time map dashboard.
We built a dedicated device TCP server to ingest live telemetry, a rule engine for geofences and custom trip events (overspeeding, loitering, exit/enter geofence), and a React Native + Node.js front and back end with a real-time map. Custom procedures were tailored to EXPO 2020. Eighteen months of focused development were followed by six months of production maintenance.
