Investigated and oversaw redesigns of many Intel Xe discrete graphics driver features, including memory location placement for different heaps, CPU overhead reduction, and shader constant data management for the DirectX drivers. Designed and implemented DX11 user mode driver’s 3D shader link time optimizations, achieving up to 19% performance gains in some games. Developed a new compiler interface and utilized threading to offload the additional compilation.Developed a driver… Show more Investigated and oversaw redesigns of many Intel Xe discrete graphics driver features, including memory location placement for different heaps, CPU overhead reduction, and shader constant data management for the DirectX drivers. Designed and implemented DX11 user mode driver’s 3D shader link time optimizations, achieving up to 19% performance gains in some games. Developed a new compiler interface and utilized threading to offload the additional compilation.Developed a driver library that collects performance data, dynamically adjusts configurations, and recompiles shaders for optimal performance. Results are saved to minimize profiling overhead. Applied optimizations to DX11, DX12, and Vulkan drivers. Co-authored a patent on the concept.Developed a methodology to quantify costly HW commands (stalls, flushes, etc.) on complex workloads in an automated software environment, and integrated this test infrastructure into a continuous integration system.Created an automated methodology for applying Microsoft Compiler's profile guided optimization to the build system, profiling popular applications to optimize hot paths in the graphics driver. Achieved up to 20% instruction reduction in popular applications. Show less

DX9 Driver Technical Lead of a team of twelve engineers. Responsible for new driver design and implementation of lightweight, immediate programming of Intel 3rd and 4th Generation Intel® Core Processors. The driver eventually replaced previous implementation with substantially less CPU overhead at the same or better GPU performance. Worked with program manager on creating schedules and milestone for the project. Contributed to the design and implemented a C++… Show more DX9 Driver Technical Lead of a team of twelve engineers.
