Responsible for software development of Android graphics API components and other graphics infrastructure.

Led software development of closed source and open source graphics drivers, shader compilers and mobile graphics services. Includes OpenGL, OpenGL ES, and Vulkan for desktop and mobile devices and game consoles.

• Software architect exploring early technical feasibility…helped sell concept to Workstations management, Corporate Vice President/staff, DreamWorks CEO, Industry Analysts.• Liaison to HP Labs team (who delivered audio/video pipeline), driving regular technical exchanges, reviews and consulting. Also worked with them to deliver needed features.• Developed features/support Nizza video engine as needed for SkyRoom.• Developed features in SkyRoom such as camera format selection, system performance assessment, pacing of codecs for best performance/quality selection.• Drove camera selection, worked with camera vendor to provide needed features/fixes.• Member of early architecture team that defined the overall architecture of SkyRoom (primary focus on video pipeline)… C++ development team employed Agile/Iterative development model with Scrum, UML and Sequence Diagram techniques.

• DreamWorks primary technical contact/technical lead - 1 of original team of 4 that approached DreamWorks, convinced them to move to HP Linux workstations - leading to a long, and highly visible relationship.• Technical lead for team that created and delivered Linux product stream that is now large part of HP Workstations revenue! • Architected/ Investigated/drove Linux technologies, technical product directions. • Led initial technical development of 3d graphics drivers for Linux by leveraging HPUX driver, delivering first commercially viable 3d Linux graphics. Solved difficult problems in Linux environment (kernel graphics driver, Xserver, accelerated device locking)• Provided technical leadership/mentoring for Linux Workstation team. • Customer Linux workstation liaison/analyst for key customers - DreamWorks, Disney, Pixar, Weta, Shell, Sandia, Intel, DCC Advisory Council, Oil & Gas Advisory Council• Primary R&D member of Oil and Gas SWAT team that resolved Linux issues along with Oil & Gas customers resulting in HP Leadership in Oil & Gas - Led 64-bit adoption initiative… Personally drove resolution of 32-bit to 64-bit transition issues on Red Hat (RHEL 3) working closely with Red Hat/Shell.• Led Linux on AMD-based xw9300, support of multi-display graphics, developing config tools, whitepapers, viz-center display wall - working closely with AMD and NVIDIA.• Technical Linux workstation liaison to Red Hat, SUSE, NVIDIA and OSLO (HP’s Linux organization).• Key proponent of blade workstations, got Linux support into POR and drove product delivery.• Developed Linux manageability tools - Bios flash/set tool and graphics config tool.• Proposed/developed 3d graphics demos CD - C++ launcher for Windows and Linux

• Led team of software engineers to deliver to very aggressive schedule for Workstation Division’s first Windows-based 3d graphics drivers for Visualize FX graphics leveraging HPUX drivers. • Delivered industry-leading 3d PC performance, winning GPC benchmarks!• Partnered closely with graphics hardware team, and workstation platform team in Grenoble, France.• Project initiated HP workstation transition to Intel PC hardware from PA-Risc hardware.

• Performance Analyst for IPF Linux/Windows graphics performance (using Intel Vtune performance tool), worked with NVIDIA to make driver changes and get 25% performance gains.• Lead HP developer for DirectModel Scene Graph and Large Model API (joint development project between Microsoft, HP and SGI). C++ development of occlusion culling/convex hull simplifier leveraging code from Corvallis Fahrenheit team- delivered alpha release.

• Technical Lead, PHIGS graphics- greatly improved performance of Toyota’s apps, partnering closely with Toyota.• Solved GM’s performance and quality issues with their advanced application using occlusion culling and polygon anti-aliasing techniques.• Led DI-Streamlines - PA-Risc assembly development of graphics primitives which greatly broadened 3d graphics performance. • Designed and prototyped graphics monitoring strategy for OpenGL and Starbase called Hooks.• Technical lead on IA64 Graphics Initiative, & Lite RAM /Ease-of-Use initiative, delivering cross-company results.

• Led team of software engineers to deliver graphics support for HP’s “Snakes” PA-Risc workstations. Joint initiative with newly purchased Apollo team. Delivered industry leading X performance and fastest software-accelerated 3d graphics! Team presented at yearly MIT X conference.• Led Snakes graphics follow-ons, graphics driver teams, release management team.• Led Test/CPE team implementing changes to greatly improve team efficiency.

• 1 of original 5 developers of HP’s Starbase graphics library (lasted for over 15 years), responsible for hi-level API, performance analysis/tuning - added lots of API features and couple of drivers to Starbase.• 1of 4 Pascal developers of HP’s graphics ROM for HP Series 500 Basic workstation.
