Everything your
devices need.

Designed to scale from prototype to millions of connected devices without changing your architecture.

Azure IoT Hub
Bi-directional communication between your devices and the cloud. Device twins, direct methods, cloud-to-device commands, and built-in security with X.509 certificates. Handles millions of messages per day with sub-second latency.
Real-time Telemetry
Stream sensor data from edge devices with sub-second latency. Time-series storage, anomaly detection, and alerting built in.
React Dashboards
Beautiful, real-time web dashboards for operators and end users. Custom charts, fleet maps, and alert management.
REST & WebSocket APIs
Clean, documented APIs for third-party integration. Node.js backends, OpenAPI specs, and SDK generation.
Security & Compliance
End-to-end TLS, role-based access control, audit logging, and compliance with GDPR and industry standards.
OTA Deployment
Push firmware updates to any device in the fleet. Delta patches, staged rollouts, instant rollback on failure.

// architecture

Azure-native,
from day one.

We don't bolt the cloud on after — we architect it in from the first device prototype.

Microsoft Azure
IoT Hub, Event Hubs, Time Series Insights, Azure Functions, and App Service. The full Azure IoT stack.
Node.js Backends
High-performance event-driven servers for device APIs, message processing, and business logic.
React Dashboards
Real-time operator dashboards with live charts, fleet maps, alert management, and device controls.
// sample telemetry API

Clean APIs.
Great developer experience.

Every cloud integration we build comes with clear documentation, typed SDKs, and real-world examples.

telemetry-client.js
const client = new FSSDeviceClient({ deviceId: 'gest-unit-0042', connectionString: process.env.IOT_HUB_CONN, }); await client.connect(); // Subscribe to real-time telemetry client.on('telemetry', (data) => { console.log(`[${data.timestamp}]`, data.payload); // → { temperature: 22.4, humidity: 58, serviceCall: false } }); // Send command to device await client.invoke('setLedColor', { r: 0, g: 255, b: 100 });
