Most of that work lives one layer below the desktop: the shell prompt, the compositor, the desktop shell, and the configuration that makes a machine reproducible. Rust first; C++ when the layer underneath calls for it; Nix when the machine has to come back identical. Whenever technically feasible, I prefer to contribute upstream rather than reinvent the wheel. Some of that work is built with friends: tuack-ng is our OI/ICPC problem-setting toolchain, whose GUI I wrote and maintain.

powerlevel11k — a prompt engine that continues powerlevel10k, in Rust. Deliberately not a shell theme: the engine owns a pty, proxies bytes untouched, and fills the header in itself, so one theme runs on zsh, bash, fish and pwsh. 80+ built-in segments mirroring p10k's, a KDL v2 theme language, three icon tiers (nerdfont / compatible / ascii), and git status resolved off the prompt thread.

  e -->|spawns inside the pty| s["theme-less shell<br/>zsh · bash · fish · pwsh"]
  s -->|"renders a prompt skeleton<br/>(placeholders)"| e
  e -->|"fills in the real header"| t

The engine never parses ANSI out of the pty stream and never touches user input. The input line stays the shell's own line editor, so completion, history and vi mode keep their geometry.

The other project I keep up with is Tuack-GUI: the GUI front-end for tuack-ng's problem-setting workflow, written and maintained by me in that org.
