Summary
🤩
Rockstar🎓
Top SchoolZhenyao Mo is a senior software engineer in Sunnyvale with 13 years of experience specializing in multimedia systems—computer graphics, geometry, computer vision, and machine learning—backed by a PhD in computer science. At Google he is a WebKit and Chromium committer focused on WebGL and GPU reliability, debugging driver issues and ensuring cross-platform graphics compatibility. His open-source work includes meaningful contributions to high-profile projects like ANGLE and Chromium, improving shader compilation, precision handling, and GPU-related stability. Earlier at Big Stage he built practical 3D solutions—automatic head completion, rigging, avatar pipelines—and solved hard multimedia engineering problems such as deadlocks and low-end streaming performance. He blends deep research training with pragmatic engineering, often surfacing subtle precision and overflow fixes that prevent real-world rendering failures.
