• Senior Software Engineer

  • Jul 2008 - May 2011

  • maintained and developed game-engine and gameplay code using C++, C# .NET, Python, HLSL with Visual Studio 2008 and DirectX 9/10 on PC Windows platforms. • supervised junior engineers. • Selected tasks include  Frame rate and memory optimization: optimized existing engine code using more efficient algorithms and techniques such as SIMD vectorization and cache/register blocking. Reduced memory usage of data structures with more efficient formats. Render state changes and draw calls were reduced.  Adding multicore support: implemented a multi-threaded task system that allowed for better core utilization. Existing code was re-structured to take advantage of the system. OpenMP was utilized to add multicore support in code modules that are not suitable for the task system. The rendering module was re-engineered to be run in parallel with other modules.  Improving rendering quality: reduced shadow aliasing with cascaded shadow map. Other improvements included ambient occlusion and N-patches. Show less
