I'm extraes, although some people might know me as "Cassini" online. I mainly use C# these days, but I've used JavaScript and TypeScript a lot in the past, as well as Python for a couple personal projects.
I initially started using C# to make mods for Unity games, and make some things in the editor, but I find myself maintaining Stargrid (BoneBoard) and Voidway Bot more than modding these days.
I primarily used to mod Boneworks and Bonelab, although I did make a Lethal Company mod that got 700k downloads, so that's neat!
