My Work
Internal tooling, IoT platforms, and freelance builds. A selection of what I've designed and shipped.

Jul 2013 – Mar 2024
The internal tool I built from the support desk at Eseye. About forty people across support, finance, sales and dispatch used it every day, and it outlived the rewrite meant to replace it.
Migrating 1.2 Million IoT Devices
Designed and shipped the multi-threaded Perl orchestration that moved 1.2M cellular IoT devices off Cisco Jasper onto Eseye's Integra platform, with under 30 minutes downtime per unit and no customer revenue lost.
NearestForest
Aug 2026 – Present
A free app that shows you the nearest Forestry England forests, closest first, and sends you there in one tap. It works with no phone signal, covers 904 forests and car parks, and has no sign-up, tracking or adverts. Designed, built and deployed in a day.
ProgressBoard
Jul 2026 – Present
A cross-project work board for building with AI agents. Cards are markdown files inside each project's own repo and the folder is the state, so a state change is a git diff. Built after classifying 35 open cards and finding 26 of them were decisions waiting on me, not work waiting on a developer.
PlanHawk
Jul 2026 – Present
One system of record for UK fire and building-safety consultancies: enquiries, projects, marked-up floorplans, issued reports and the money still owed, with every change kept. Multi-tenant, built on a temporal data model, and live as a demo.
Homelab
Oct 2026 – Present
An old workstation rebuilt as a Proxmox server: a NAS, Home Assistant, photos, git and a dozen apps, each with its own HTTPS name, none of them open to the internet, and a status page that checks every one each minute.
