For more than ten years, I have worked close to hardware: firmware, RTOS-based systems, embedded Linux, secure peripherals, manufacturing diagnostics, and the debugging that starts when a device leaves the lab.

Vertices is how I bring that experience to teams building connected products. I care about the work that turns a promising prototype into software that can ship, be maintained, and keep working in the field.

Selected experience

A compact background.

02

Connected buildings

Smart & Connective

Low-power firmware, wireless communication, sensors, developer workflows, and CI/CD for smart thermostats and occupancy devices.

03

Wearables and field reliability

Equisense & Spire

Bluetooth Low Energy trackers and wearables, bootloaders, firmware updates, power optimisation, sensor processing, and production releases.

What I care about

The unglamorous work that makes a device trustworthy.

  • Reliability when the device is in the field, not just on the bench.
  • Clear boundaries between hardware, firmware, and the systems around them.
  • Software that your own team can understand, test, and build on.

Why build in public

I’m also exploring what trusted machines can do next.

Alongside client work, I am building the Vertices SDK in public: an open-source initiative for verifiable devices, Physical AI, and the Economy of Things.
The original C SDK, an Algorand wallet for IoT devices, remains available on GitHub.

Explore the SDK roadmap

If you’re building a connected product, I’d be glad to hear about it.
