Summary
🤩
Rockstar🎓
Top SchoolDavid Worsham is a Staff Software Engineer with 13+ years specializing in GPU programming and real-time rendering for consumer and embedded platforms. He has led multi-engineer teams at Google and EA to ship high-performance renderers powering tens of millions of devices and games, tuning GPU workloads to sub-millisecond frame times and enabling 60 FPS across constrained hardware. Deep experience with Vulkan (including authoring a zero-copy GPU resource sharing extension), ANGLE-based OpenGL→DirectX work, and shader/register optimizations underpins his system-architecture focus. A contributor to the Flutter engine and framework (notably Fuchsia-specific scene/ViewHost integrations and threading fixes), he blends low-level graphics engineering with production-scale product delivery. Based in Sydney, he pairs academic grounding from Georgia Tech with hands-on profiling using tools like RenderDoc, PIX and Razor to squeeze performance from complex pipelines.
