Services

The engineering behind the products, on its own.

Small, senior team. Bench to site. We take on the jobs that need both a soldering iron and a protocol analyser.

01

Firmware & hardware

ESP32, RP2040 and PIC firmware; PCB design through to fabrication-ready packages; secure OTA update infrastructure; security review of embedded web interfaces. PoE, RS-485, CAN, 4G.

02

Protocol reverse-engineering

Legacy buses and undocumented serial protocols decoded, documented and re-implemented, so a twenty-year-old system can be maintained, bridged to modern platforms or replaced in stages instead of ripped out.

03

Integrations

Nurse call to clinical messaging (Olinqua, Ascom — TAP/IXO); building management over BACnet/IP (Honeywell EBI and others); MQTT displays and dashboards; reporting pipelines; UniFi Protect and Modbus.

How we work

Fixed-price discovery first — a week or two to read the system, bench what's unknown and write down what we found. Then a quoted build with milestones you can see running. You own the IP of what we build for you unless we agree otherwise.

Have a system nobody wants to touch?

That's usually where we start. Tell us what it is and what it needs to do.
