Summary
🤩
RockstarEd Mackey is a Senior Software Developer with 14 years of experience, currently at AGI, who specializes in 3D graphics tooling and runtime asset delivery. He is an active contributor to the Khronos Group’s glTF ecosystem—working on the VSCode extension, Blender exporter, validator, sample models, and next-generation PBR materials—and has improved rendering quality in the glTF Sample Viewer. His work spans full-stack development in high-profile open-source projects like Cesium, where he implemented UI and playback features, and CZML tooling for geospatial visualization. Comfortable across front-end rendering, Blender Python integration, and back-end maintenance, he focuses on practical fixes and refactors that boost interoperability and real-world model support. Based in West Whiteland Township, PA, he brings a quietly deep specialization in physically-based rendering pipelines and file-format tooling that often lives at the intersection of graphics engineering and developer ergonomics.
