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.
• I'm a huge fan of open source and Free (as in Freedom) Software, the right to own, the right to modify, and and the right to repair.
• If you're interested in what I get up to, follow me on Bluesky (@invoxiplaygames.uk). (I'll work on a proper blog soon, I promise)
