IoT Products
Connected devices, built end-to-end.
Hardware, firmware, cloud backend, and mobile app — all under one engineering roof. We build IoT products that work in the field, not just in the demo.

IoT Products
An IoT product is never just a device. It's hardware talking to firmware, firmware talking to cloud, cloud talking to an app, and an app talking to a user. Every link in that chain has to work.
We design and build connected products where we own all those links — or work alongside your team to close the gaps. Either way, you get a system that holds together from day one in the field.
We've shipped sensor nodes that run for years on two AA batteries, and LTE gateways pushing telemetry from outdoor industrial sites — and everything in between.
We take your IoT concept from hardware to cloud to app — owning every layer so nothing falls through the gaps between teams.

End-to-End Products
The biggest IoT projects fail at the handoffs between hardware, firmware, and software teams.
When we own the whole product, there are no handoffs. The hardware engineer who designed the board is the same person telling the firmware engineer what peripherals are available. The firmware engineer who wrote the MQTT client is the same person helping wire up the cloud backend.
We've delivered ParcelPoint — a complete smart locker system — as an example of this: custom PCB, embedded Linux firmware, Qt/QML kiosk UI, M-PESA payment integration, and a cloud backend, all by the same small team in three months.
If you have a concept and need it built, this is how we work.
Cloud & APIs
Device data has different characteristics to web traffic — high frequency, small payloads, unreliable connections.
We design backends that handle these characteristics correctly: MQTT brokers for real-time device telemetry, message queuing for devices that come online after extended offline periods, and time-series storage for sensor data that needs efficient range queries.
REST APIs for configuration, command-and-control, and integration with third-party platforms. Admin dashboards for fleet operators. Webhook pipelines for integrating device events into your existing systems.
We've deployed on AWS IoT Core, self-hosted MQTT stacks, and hybrid architectures — the choice depends on your scale, cost envelope, and data residency requirements.
Wireless & Protocols
Connectivity choice is one of the most consequential decisions in IoT product design — and one of the most commonly rushed.
We evaluate range, power, data rate, infrastructure requirements, and cost at volume to recommend the right stack. LTE-M and NB-IoT for wide-area low-power devices. LoRaWAN for multi-year battery life with kilometres of range. BLE and Wi-Fi for short-range, higher-bandwidth products. Cellular LTE for gateways and kiosks that need always-on connectivity.
On the wired side: Modbus RTU/TCP for industrial sensor integration, CAN bus for vehicle and automation systems, RS-485 for multi-drop sensor networks.
We write the protocol stacks, handle the modem AT command interfaces, and design the antenna layouts — soup to nuts.
Companion Apps
The mobile app is often the only part of your IoT product the end user ever touches.
We build Android apps (and iOS where required) that handle device discovery and pairing — QR code, BLE, or NFC — real-time status and telemetry over MQTT, and configuration interfaces that map cleanly to what the firmware actually exposes.
Our SquaredIoT app is an example: pairing, live device monitoring, and control — built alongside the firmware it connects to, so the interface and the device always stay in sync.
We can build standalone apps or integrate device connectivity into an existing app your team maintains.
