Professionally, I'm working on the frontend of a radio frequency propagation simulator for 3D "digital twins" of cities/regions. This uses ImGui under the hood, but is wrapped by Python. It's a bit of a pain, but I came up with a class that allows the UI to be composed in a manner more akin to React Components.

For fun, I just implemented a finite-state machine for a videogame I'm working on in Rust. It's used to swap out sprite animations depending on the state of its parent entity. I'm glad to be solving problems I'd never come across in my normal line of work.
