Started on Roblox when I was young. Got into it seriously around 2016 and spent years learning how the platform actually works at a low level. Luau, networking, how the engine handles things, where the weak points are.
Security is what I care about most. I know what it looks like from both sides. Now I build games where the anti-cheat and the architecture are thought about from the start, not added later. I also do backend and frontend work outside of Roblox.
