Electronics & software engineering

We turn ideas into products that ship.

We design the electronics, write the firmware, and build the software to run it all. Connected products developed as one system, from first schematic to field deployment.

Capabilities

From schematic to shipped product.

Nine disciplines under one roof, so hardware and software decisions get made together instead of thrown over a wall.

01
PCB design & layout
Schematic capture, multi-layer layout, signal integrity and design for manufacture.
02
Embedded systems design
MCU and SoC selection, power budgeting, sensor integration and system architecture.
03
Firmware development
Bare-metal and RTOS firmware, bootloaders and secure over-the-air updates.
04
Hardware manufacturing
Prototype runs, DFM review, test fixtures and end-of-line production testing.
05
IoT & connectivity
BLE, Wi-Fi, LoRaWAN and cellular, with device provisioning and fleet management.
06
Embedded software engineering
The tooling, drivers and services that sit around firmware and keep it maintainable.
07
Control & desktop applications
Machine control, configuration, diagnostics and data logging for operators and engineers.
08
Web platforms & dashboards
Telemetry portals, device management and reporting across an entire fleet.
09
Integrated control systems
Lighting, audio, sensors and effects synchronised across many devices, with a control room interface and automatic recovery.
Selected projects

Work that shipped.

A small selection of connected-product projects. Each one designed, built and handed over as a complete system.

Our own product

Sensydash, built and run by us.

Wireless sensors, a live dashboard and instant alerts for kitchens, farms and buildings. We designed the sensor boards, wrote the firmware and built the cloud platform, and we install and run it for every customer.

Leadership

How we work
01Discovery call

A conversation to understand what you are building, the constraints, and whether we are the right fit. No forms, no pitches.

02Scope & proposal

A written plan with architecture, components, milestones and a fixed price. We refine it through as many rounds as it takes until both sides are confident.

03Build in iterations

Development in short cycles with checkpoints you attend. As hardware is tested and requirements clarify, we adjust scope together.

04Handover & support

Production files, firmware, full documentation and support during the first run. We stay reachable after the project closes.
