On the workbench.

A few things I’ve made, from useful software to things sent into the sky.

3D printing · Open source

Tracefinity

Turn photos of your tools into custom Gridfinity bins. Trace the outlines, arrange a layout, and export STL or 3MF files ready for printing.

Mac app · 2026

Snag

A fast, native file manager for the Mac. It splits each transfer into parallel threads, retries the chunks that fail, and picks up where it left off, even after a restart.

Developer tool · Open source

docket

Every open pull request and issue you’re involved in, live in a terminal or a browser tab, with CI, what’s left before merge, and how long since a person last touched each one.

GitHub

Home automation · Open source

Home Assistant integrations

An unofficial integration to arm, disarm and monitor HKC alarm panels, and a sensor for ESB Networks outages, faults and restorations near you.

Hardware experiment · 2013

Arduino balloon tracker

An Arduino Mega flight computer with a GSM modem and radio telemetry, built for a high altitude balloon.

Clouds and the curve of the Earth, photographed from the balloon payload.

From the field · 2013

High Altitude Adventures

A homemade payload, a helium balloon, and a camera with a rather good view. The launch, the chase, and the recovery.

At work

I work at Red Hat on Kuadrant, gateway policies for Kubernetes. Some of what I’ve worked on there:

Kuadrant console plugin
Kuadrant in the OKD and OpenShift web console.
Kuadrant Backstage plugin
Manage Kuadrant policies and APIs from Backstage and Red Hat Developer Hub.
MCP Gateway
An Envoy-based gateway for MCP servers, with Istio integration and policies for authentication, authorisation and rate limiting.
kuadrant.io
The project’s website and documentation.
oinc
OKD in a container, a single-node cluster with the OpenShift console for local console plugin work.
