About

Hey, I'm Emma - I love to play around with and tinker with old tech, making them better and/or bringing them into the modern age.
I'm also a hobbyist reverse engineer and security researcher, familiar in working with tools like Ghidra, Fiddler and mitmproxy.
- I've found and reported several security vulnerabilities, small and large. Some responsibly disclosed via HackerOne.
Most of my software is developed primarily in C# (.NET and ASP), C (often embedded), C++ and NodeJS. I also sometimes work with PHP, Python, Objective-C and Swift in a few older projects.
- very enthusiastic about PowerPC and other RISC processor architectures!
I enjoy playing (and tinkering with) a few games, like Rock Band 3, AUDICA, Fortnite, Mario Kart Wii, Beat Saber and Guitar Hero Live. You might catch me making mods for these games on my GitHub.
If you're interested in what I get up to, follow me on Mastodon (@[email protected]) or Bluesky (@invoxiplaygames.uk). (I'll work on a proper blog soon, I promise)
