• integrated WWise sound system, including editor support and integration with WWise toolchain (gained basic experience with wxWidgets),
• optimized game on X360 (reduced hitches by parallelizing costly operations, cut per-frame L2 cache misses by over 20%),
• ported MemTracer to X360 and found a way to save over 70MB of memory,
• helped in developing an ambient occlusion baking tool (wrote KD-tree based raytracer, multi-threaded for maximum efficiency),
