Please note that I am not seeking new job opportunities.

I am a computer graphics enthusiast who enjoys C/C++ development, especially when it is close to the metal. I've worked on shader compilers, surgery simulators, video drivers, raytracers, shading tools, lighting tools, DirectX debuggers, OpenGL ES debuggers, and graphics-intensive web applications.
