Senior software engineer, Brisbane
I build backend services at Sony Interactive Entertainment (PlayStation). Before that I worked on betting and lottery platforms at Entain and Jumbo Interactive. This page is the other half: what I have built on my own time since 2014.
2025–now
A review gate that sits between an AI model and the people who use its output. Rules written in Lua approve a response, reject it, or send it to a person to check. The rules can be changed without a deployment, and the corrected response goes back to your app by webhook.
2024–2025
A search engine for scientific papers, for people who need to get through a reading list. Every paper comes with a plain-language summary written by a language model, and a citation ready to paste in APA, MLA, Chicago or Harvard style.
2023
A budgeting tool for people working towards financial independence and early retirement. It tracks income, expenses and savings rate, and projects how the balance compounds. An assistant answers questions with your own figures as context, using retrieval over Pinecone and the OpenAI API.
2019–2021
Pick a passport, or several, and see which countries you can enter without a visa. It runs as four services: a Go API and scraper, a Node.js backend and a React frontend, deployed with Jenkins to Docker Swarm on DigitalOcean.
2017
An event sharing app built for places with poor connectivity. It leans on service workers and in-browser data stores so it stays usable when the network does not.
2014–2016
A real-time 3D action strategy game for Android, with enemy AI I wrote myself. Published on Google Play, where it has passed 1,000 downloads.
