About Me
Who am I?
Back in 2013 (when I was just 8!), I discovered Roblox, which piqued my interest in game development and programming. I started off slowly with Lua, which is used to develop games inside the Roblox game engine, and ended up diving deeper and deeper into the rabbit hole of game development.
As I grew older, my curiosity led me to explore other topics like reverse engineering, security, parsers, and web development. Along the way, I also became fascinated by UI/UX design and this has ultimately shaped a lot of what I do today.
This evolving interest has been a driving force behind my nearly 9 years of hands-on experience in Roblox development. I've left a notable footprint in the Roblox open-source community, primarily with libraries and tools aimed at standalone usage of Luau.
While my roots are in Roblox, I've broadened my horizons, gaining experience in both frontend and backend development, which is how this site came to be! I'm currently pursuing a bachelor in Software Engineering at NHL Stenden, from which I'm expected to graduate in 2027.
