Experience

Iridium

https://github.com/fhaynes/iridium
A programming language, compiler, assembler, and VM written in Rust along with a series of tutorials documenting the development process. It is a register-based VM, the fastest but most challenging type to write, so there are not many tutorials about them.

Amethyst

A Rust-based 3D game engine that utilizes Vulkan and a modern ECS system. This is a large open-sourced project that I joined early on and led the founding of the Amethyst Foundation as an official nonprofit so we could accept donations.

Laminar

https://docs.rs/laminar/0.5.0/laminar/
I led the development of a low-level networking library based on UDP and intended for games and other applications with low-latency requirements. It's been used in multiple game engines as well as some proprietary load balancers and firewalls.
