Product & Graphics Software Engineer

Joined mid-cycle to support Dragon Age 4.  Focused on improving project health by supporting bi-annual engine (frostbite) integrations, reducing code divergence, improving rendering performance, and prioritizing and tracking down high risk issues in unmaintained systems.

BioWare

Senior Graphics Engineer

- Led performance improvement efforts on AR surfaces for google maps.  Doubled frame-rate via rendering optimizations.
- Conceptualized, led and designed a 'split-screen' map mode for Street view on Mobile Google Maps.  Implemented the Android version.
- R&D work on future versions of street view.  Upgraded native C++ renderer to support GLES 3 (from 2.0) as well as architected additional capabilities to the Google Maps native renderer, such as animation, model import, and more.
- Created a technical roadmap for future renderer improvements.

Google

Staff Software Engineer

- R&D, designed and authored a realistic, configurable AR makeup shader implementation for Instagram's makeup partners.  Developed a novel method for reconstructing real-world incoming light direction in the vertex shader, on GLES 2.  Allowed for the first time, end-user configurable specular and glitter responding to light in the camera feed.

PRO Unlimited

Freelance Graphics Programmer AR

- Conceptualized and led product development of 'Ocean' VR demo - a raymarched underwater rendering demo demonstrating the capabilities of Google's standalone VR hardware - used to market platform capabilities.
- Conceptualized and developed performance analysis tools for Google's VR-Unity integration.  Developed internal tools for evaluation of the platform, which led to the discovery of multiple low-level issues, including driver level issues which had caused multiple titles to run below 30fps, when they were capable of running at 60fps.
- Developed partner tools, including on-screen performance analysis tools in Unity, and established new best practices, based on tested metrics proven using aforementioned performance tools.
- Supported VR platform via advocating on behalf of third party VR developers, and supporting those developers as a technical and graphics expert.
- Additionally consulted and developed shaders as an internal graphics optimization expert on multiple projects, including ILM's VR demo, web-based 3D platform Poly, and multiple developer samples.
- Developed a prototype of 3D photos using ML for depth-from-single-image, as well as shaders to enable rendering the 3D photos in VR on low-end devices.

Sr. Software Engineer

- Led engineering on Camaro Six, a Unity-based Camaro customizer app for iOS and Android.
- Established engineering priorities, mentored other engineers, established foundational architecture, and directly implemented graphics and interactive aspects of the application.
- Established Unity production pipeline and process, as well as leading technical art.
