I learned the c++ language during elementary school period, and later I also learned c# (for Unity3D game dev), Python (for a bunch of things), and Java (for Minecraft mods dev). Almost all knowledges and skills about CS are learnt by myself. I’ve developed a lot of game demos on my own and have one game published on TestFlight (coming soon on App Store/Google Play) . I’ve also done a lot of computer related stuff, such as tried to decompile a mobile rhythm game, deployed “Stable Diffusion” on my own PC, created a short CG with Blender for the 9th 3D Render Challenge, composed a lot of music works in the past few years and uploaded them to a music platform, and so on. Suffice it to say, as long as I have a computer nearby, I can create a anything I want.
