👋 Looks like you've found my profile :) Enjoy your stay!
💣 I'm a reverse engineer and software engineer that mostly dabbles around in Rust, C++ and various Assembly languages.
👹 I spend most of my free time working on low-level projects such as but not limited to reverse engineering software (malware, anti cheats, games, ...), writing emulators, creating reversing & exploit development related tooling and implementing compiler related programs (usually for obfuscation and/or deobfuscation).
🕹️ I retired from playing CTFs after co-founding and playing alongside organizers but occasionally help out or look into challenges out of curiosity.
🔑 Most notable credentials are my teams' (through 2019 excusemewtf and 2020-2022 organizers) CTF rankings along with my personal ranking on HackTheBox (retired; peaked at global #2), along with the projects on my GitHub.
🕸️ I infrequently blog about my shenanigans over on my blog layle.me.
✉️ You can contact me on Discord via mrlayle.
