Welcome to my home on GitHub. Here you'll find repositories related to both my professional work and personal hobbies.

OpenJDK

I work at Oracle on OpenJDK, where I contribute to the JDK. I have also developed a VS Code extension to support OpenJDK development: vscode-openjdk-devel.

Minecraft

I like playing Minecraft, but I love coding for it. 😄 I’ve created several mods:

• Status Effect Timer: overlays a timer on the Vanilla status effect HUD icons
• Mod Settings: provides an easy-to-access configuration screen for all installed mods
• Elytra Indicators: provides Vanilla-style "fly by instrument" support for elytra flight

I’m also the Lead Developer and a main contributor to Wynntils — a must-have mod for Wynncraft, the world’s largest Minecraft MMORPG.

Another popular tool is pmanvil-converter, which converts Bedrock Edition worlds created by PocketMine to Nukkit format.

Other Work

Some of my other specialized utilities include:

• pppp-dissector: a Wireshark dissector for the PPPP protocol
• playgrabber: downloads videos from svtplay.se
• icecc-indicator: an AppIndicator monitor for icecc/icecream

I like to preserve historical codebases. Some projects I’ve rescued include:

• phoneME: the open-source Java ME implementation by Sun
• OpenKOM: a versatile, terminal-based social community platform

A long time ago, I helped kick off the early explosion of instant messaging clients by reverse-engineering the ICQ protocol, and providing a space for ICQ clone developers to collaborate. I’ve documented some of that history on my Historical ICQ page.
