Developing a variety of new rendering and world building technology for our next title, The Pathless.

Heavily modified the UE4 rendering and material pipeline to support a variety of custom visual effects and artist-driven environment rendering. Implemented fully custom rendering and authoring pipelines for water, kelp, translucency, atmospheric lighting, terrain, and instanced static mesh morph target animation. Shipped on PC/Steam, PS4, PS4 Pro, Xbox One, and the Windows 10 Store, each with special platform considerations and tuning.

Worked with a variety of game and app developers to debug, tune, and enhance their titles for the NVIDIA Tegra platform. My focus was primarily on Unreal Engine 3 and 4, helping to port both to next generation mobile hardware.

Worked primarily as a game engine generalist and, through either new feature development, driving titles through to shipping, or general bug hunting, worked with most of the major systems in the multi-million line Unreal Engine code base. Worked very closely not only with the rest of the engine team, but also with gameplay teams, testing and QA, production, and external partners on various engine and title initiatives. In particular, as a member of the Platform Team, I focused on porting and maintaining the engine and its full suite of tools across a wide array of hardware and software platforms, with a particular focus on mobile platforms.

Worked on various graphics debugging and performance analysis tools. Served as technical and design lead for PerfHUD 6.x, helping to implement a massive and modernizing overhaul of the tool suite.

As an OpenGL driver engineer, I developed core system software and extensions, shared across the full cross-product of OSs (Win9x/2000/XP/Vista, Linux/UNIX, DOS), CPUs (IA32/64, AMD64), and NVIDIA GPUs from NV4 through G9x

Worked as a core Engine, Graphics, and Scenegraph developer on our cross-platform, high performance engine: Alchemy. Shipped Alchemy middleware v1.0 and v1.5 for PlayStation 2, Xbox, GameCube, DirectX, and OpenGL.
