Projects & things I've shipped

Live products, client websites and side projects — built end to end, from first commit to production.

Bonball

Android · In development

A fast, top-down, physics-driven football match. Two teams of three players compete in short, intense rounds, scoring goals with a single shared ball. Controls are minimal — move plus two buttons — so depth comes from positioning, timing and teamwork. Built to support a competitive ranked ladder later, which means fairness and responsiveness matter more than visual complexity.

Krem Roster Maker

Live · Maintained

A rostering tool for small business managers, built with React Vite and Firebase. Live in production and actively maintained off the back of real user feedback — end-to-end product ownership from build through to the people actually using it every week.

Two-Phone Game Platform

Real-time

Real-time multiplayer platform with three mini-games — Tag, Sumo and Pitch — over WebRTC and PeerJS. Sticky reconnection, latency probes, score animations, round progress, intermission cards and a final winner screen. Fully static deploy: phones connect directly, with PeerJS's public broker handling only the initial handshake.
