I build developer tools and games. Most of the work on this page is published somewhere you can install it or play it: the JetBrains Marketplace, NuGet, npm, Steam and the browser.

I study at Monash University and I am looking for work as a software engineer.

Monopoly Deal

The Monopoly Deal card game in the browser, with no game server. The host's browser runs the rules and sends each guest only what that guest is allowed to see.

A player who reloads gets their seat back within 120 seconds. Vitest covers the rules and Playwright plays full games end to end.

TypeScript, React, Zustand, Zod, WebRTC through Trystero

A plugin for JetBrains IDEs that flashes the text you copy, so you can see what went to the clipboard. It works in every IntelliJ based IDE and has more than 1,200 downloads.

Claude Agent SDK for .NET

A typed C# SDK for the Claude Code agent protocol, ported from the official Python SDK. It supports streaming, hooks, tool permissions, sessions and MCP tools.

It works with NativeAOT, so the JSON schemas are made at build time.

Outlook Mail MCP

A read-only CLI and MCP server that searches personal Outlook mail through Microsoft Graph. The CLI and the server share one core.

Zod checks every Graph response, and 232 Vitest tests run against a mocked Graph.

agsearch

A command line tool that searches local Claude Code and Codex conversation transcripts. It reads both formats into one typed model and reports failures and token use.

Each release has native binaries for Windows, macOS and Linux.
