This page lists all my projects that I've worked on.

Personal projects

Applications

Preserve (2020-Present) - Gitlab

Music player as a client for Jellyfin, a selfhosted media server. Written using Vue and Typescript.

Olympia (2019-Present) - Gitlab

Gameboy emulator written in Rust, written to understand older systems in more detail. Covers a complete CPU emulation.

PyIRCd (2011) - Github

An IRC daemon written in Python. It is a pretty complete implementation in terms of a managing a single IRC server, but was not complete for the purposes of managing a network of interlinked services.

Libraries

kdbx-rs (2019-Present) - Crates.io / Gitlab

Library for managing databases from the keepass password manager in Rust.

Xray (2018) - Crates.io / Gitlab

A library for screenshot testing Rust applications, written for use in a personal game project I was working on.

Ludum Dare

Ludum dare is a biannual game jam where the goal is to make a game within 48 hours based on a theme given at the start of the contest time. I've entered on 5 occasions.

Mana Tactics (LD55 - 2024)

A tactics based game based around summoning elementals and protecting your summoner. Included a number of features like unit economy and terrain with different effects.

Grand Vizier (LD40 - 2017)

A second attempt at Ludum Dare, with a slightly increased scope. The theme of this Ludum Dare was "The more you have, the worse it gets". I interpreted this based on the quote "The tighter you grip, the more star systems will slip through your fingers", and did a strategy game where you played as an evil vizier who needs to track down and stop the hero from overthrowing you, but each action you took would increase unrest and increase the chanceo of being overthrown.

Generation Ship (LD38 - 2017)

This was my first time entering Ludum Dare. The game was a very simplistic spaceship resource management game where the goal was to keep your crew alive long enough to reach their destination.
