Work Production systems for dealers and tenants, and a fuel app for the drive home.

Revala

A fuel and charging map for the drive you are already on. Revala reads every official price feed in Australia and the UK's Fuel Finder, plus UK chargers over OCPI, and answers which stop on this road is worth it — along the route, open when you arrive, and whether the detour pays for your own tank. An iPhone app, a core on Cloudflare Workers and an owner's console behind Cloudflare Access that runs the service — health and incidents, re-running failed jobs, station corrections, monthly cost and release stages switched without a new build; built since March 2026, formerly Servo Map.

Where Should My Data Live?

What limits how well we use AI stopped being model capability a while ago — it's that the data about me isn't mine. Any product can be swapped out; the only thing keeping you in place is the context that has settled inside it. I built a personal database to fix that, and building it showed me it's only a mirror.

From a Website Assistant to a Personal Knowledge Interface
What began as a cited Q&A assistant for this site became two interfaces over Kioku: a public RAG path for visitors and a private MCP tool surface for my AI, sharing one source of truth without sharing permissions.

Ghostty + Tmux: One Tab Per Project, One Pane for Claude, One for the App
How I use Ghostty tabs as project slots and tmux as the split manager — why tabs stay visible, why splits live in tmux, and the config choices that make eight projects open at once stop feeling like eight projects open at once.

Photography The same eye for structure shapes a service boundary, a deployment pipeline and the edge of a frame.
