Games I've Worked On
Solar Ash - TBR
Graphics Engineer
Implemented the NPR surface shading model in use by most objects in the game. Developed and optimized a system for rendering dynamic, large-scale clouds. Miscellaneous graphics tasks, and extensive optimization.
Mario Kart Live: Home Circuit - 2020
Programmer
Nintendo Switch
Implemented a modern GPU hardware abstraction layer with multiple backends, a forward+ renderer with a PBR shading model, and designed and implemented a custom scripting language.
Crash Bandicoot Remastered (Not Officially Credited) - 2016
Vicarious Visions Alchemy Team
Developed a high-level shading language and system for processing and translating input shaders written in a subset of C++11 to various platform-specific shader languages. Implemented high-quality fur rendering.
Skylanders: Imaginators - 2016
Vicarious Visions Alchemy Team
Ported engine to Linux and did additional work for rendering out high quality images at print resolutions as a backend service.

Personal Projects
BLSL
Github
BLSL is a high-level shading language I'm working on. The intent is to fill the middle ground between languages like Cg and FX that force the user to fit into a rigid framework, and platform-level languages which offer little/nothing in the way of solving application-level problems.
laminaFS
Github
LaminaFS is an asynchronous, virtual overlay filesystem. It supports user-defined "devices" for mounting archives, network paths, or whatever, and comes with a "directory" device out of the box.
dib
Github
Dib is a build system designed to leverage the Haskell language's features (build scripts are written in Haskell) while being more flexible and easier to use than systems like GNU make. Contrary to most build systems, it is a forward build system, meaning that products are defined from their pieces and built in the natural direction versus as an implicit graph driven by production rules.
2A03
Github
2A03 is a minimalist synthesizer based around the features present in the NES CPU of the same name. Songs are compiled from a high-level assembly language into bytecode that is then interpreted by the synthesizer.
libwaffle
Github
Libwaffle is a light-weight, modular synthesizer library that utilizes JACK for output and includes OSC support.
LuaGame
Repo
LuaGame is a rapid development tool for games that is based around the Lua programming language, SDL, and OpenGL.
