On the shelf
Three products I designed, built and run myself, and a piece of published research. Each one is live, so you can pick it up and look underneath.
Climate policy simulator
Tiny Aotearoa
A free tool for trying ideas to cut New Zealand's greenhouse gas emissions. Move nine levers, from electric cars to native planting, and a 3D island shows what happens to emissions out to 2050 and what it could cost or save.
- Checks every plan against the legal net zero and methane targets, and links each figure to a published source.
- Built to work with screen readers and keyboards, on a phone or a slow connection, with accessibility checks in the automated tests.
- No accounts, no cookies and no tracking. A plan is stored only in the link you share.
- My part
- Solo project: design, build and upkeep
- Made with
- React, TypeScript, three.js with react-three-fiber, Vite, Vitest, Playwright with axe
US fuel price analysis
GetPumpRate
An independent site that turns the US government's weekly fuel price data into something a driver can use: where this week's price sits in its 52 week range, what a gallon is made of, and why one state pays more than another.
- Server-rendered pages for the national average, the five supply regions and nine states, each refreshed from the EIA Open Data API and cached so the source is never hammered.
- A published methodology gives the formula behind every computed figure, so readers can check the numbers line by line.
- Includes a fuel cost calculator, a state tax comparison and price alerts.
- My part
- Solo project: design, build and upkeep
- Made with
- Next.js, React, Recharts, Upstash Redis, EIA Open Data API, Vercel
Mobile app for iOS and Android
Veil Moments
A quiet daily quotes app. Say whether you're struggling, okay or thriving, and it sends a quote matched to your mood at the rhythm of your day.
- Live on the App Store and Google Play, with a paid tier that adds tone filters, mood history and an evening notification.
- One Flutter codebase for both platforms, with local notifications scheduled to the user's time zone and saved quotes kept on the device.
- A small Node.js service serves the quote library, filtered by mood and tone, and skips quotes the user has already seen.
- My part
- Solo project: design, build and upkeep
- Made with
- Flutter, SQLite, in-app purchases, Node.js, Express
Peer-reviewed research paper
Googling it
A study of how Google's news search results shape the way newsrooms see social issues. It found that results can affect a newsroom's perception, but journalists mainly rely on search for complementary information.
- Co-authored with Verica Rupar, Merja Myllylahti, Haley-Georgia Jones, Weihua Li and Mahsa Mohaghegh.
- I built the data pipeline as a research assistant at Auckland University of Technology: comparing ways to collect Google search results, then running natural language processing over what came back.
- Published open access in Interactions: Studies in Communication & Culture, volume 13, issue 3, pages 253 to 273.
- My part
- Co-author, data collection and analysis
- Made with
- Python, React, Google Colab, pre-trained NLP models

Off the clock
Grew up around art in Kuala Lumpur. Found code on a trip to San Francisco and never really put it down.
Auckland's home now. If I'm not at a keyboard, I've got clay on my hands, throwing pots or building sculptures. There's always music on, and I'm actually listening, not just letting it play. The pot up top is the only one of mine that can't crack in the kiln.
At work I care about the unglamorous parts: reading the regulations properly, writing tests that catch real problems, and showing where every figure comes from so anyone can verify it.
