About

Hey, I'm Emma - I'm a developer who works on various projects that primarily revive or add features to outdated hardware/software (as well as some utilities, here and there).
Most of my software is developed primarily in C#, C, C++ and NodeJS. I also sometimes work with PHP, Python, Objective-C and Swift in a few older projects.
- very enthusiastic about PowerPC, and systems that use that architecture!
I enjoy playing (and tinkering with) a few games, like Rock Band 3, AUDICA, Mario Kart Wii, Beat Saber and Guitar Hero Live. You might catch me streaming these on my Twitch channel, and mods for these games on my GitHub.
I'm a hobbyist reverse engineer and security researcher, familiar in working with tools like Ghidra and mitmproxy.
- I've found and reported several security vulnerabilities, small and large. Some reported via HackerOne.
If you're interested in what I get up to, follow me on Mastodon, Bluesky or Twitter. (I'll work on a proper blog soon, I promise)
