Hardware & Embedded

IoT & Connectivity

Connecting devices to phones, gateways, and clouds. Custom BLE profiles for companion apps, LoRaWAN for fields without WiFi, MQTT brokers backed by AWS IoT or HiveMQ for fleets, and cellular fallback when the WiFi router is unplugged. We build both ends — the radio code on the device and the broker, device shadow, and dashboard ingestion on the cloud.

What we offer
