Rockstar🎓
Top SchoolCourtney Goeltzenleuchter is a retired engineer with over three decades of graphics and systems software experience, including 11 years focused on modern graphics stacks and five years as a Google Android engineer. He led 3D technology efforts at LunarG and architected OpenGL/driver solutions at HP and Evans & Sutherland, combining low-level kernel and driver expertise with higher-level compositor and WSI work. Courtney has been an active contributor to the Vulkan ecosystem—improving loader, headers, validation layers and tooling across prominent Khronos and Android repositories—demonstrating deep knowledge of Vulkan layer initialization and debug/reporting infrastructure. Based in Fort Collins, Colorado, he brings a practical blend of systems engineering, API design, and platform integration experience. Notably, his open-source commits show a habit of keeping projects current with evolving Vulkan specs and removing legacy cruft to simplify long-lived codebases.
