Work Production systems for dealers, tenants and badminton courts.
EFFICIENT System
A multi-tenant wheels and tyres ERP and commerce platform — one Django backend, a shared React UI kit, five portals, a storefront, and a Rust CLI with an MCP server. My layer is the one underneath: a shared engineering contract, with agent workflows that hold its repositories to that contract.
SlateCourt - Badminton Venues & Games
A mobile-first PWA for Sydney badminton: a 54-venue directory with live court availability aggregated from the venues' own public booking pages, a game ledger with bill-splitting and a gear log, plus friends, groups and notifications. A personal, non-commercial demo — bilingual, self-hosted, registration by invite code only.
Personal Website
A bilingual portfolio with an AI assistant grounded in the site's own content, privacy-first analytics, blog, photography gallery, and WCAG AAA colour contrast — self-hosted on my own Docker stack, all solo-built.
Writing Notes on personal data, knowledge interfaces and the terminal behind the work.
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.
