Welcome to my portfolio.

Through my career in and out of the games industry I have worked on many C++ and C# projects and when I am not on the clock I continue to learn through my hobbies and personal research. Here is a brief overview of my professional experience and skillset, as well as some of the projects I have worked on over the years.

Over the years I have played around with technologies ranging from programming languages and shaders to profiling and DCC tools.
