I spent over a year working on a mod for the video game CSGO, written entirely in C++. It was almost entirely made from scratch, and gave me a lot of insight into low-level programming, managing memory and raw assembly.

The actual program made use of the popular Dear ImGUI framework to provide an interface for users to interact with the mod.

I've also experimented with using C++ for network programming, making a small game server using raw Windows (and Linux) UDP sockets.
