Rockstar
Top expert inWebGL and Interactive 3D Graphics Development
Takahiro is a seasoned software engineer based in Niigata, Japan with 12 years of hands-on experience in front-end development, 3D graphics, and test automation. He contributes to high-profile open-source projects such as three.js and Google's model-viewer, where he fixed AR rendering issues and extended loader/renderer capabilities for formats like KMZ and glTF. Comfortable across VR/AR stacks (A-Frame, WebXR, Hubs) he blends UI polish—audio controls, sign-in flows—and deep rendering fixes that improve performance and robustness. He also brings rigorous QA discipline from RISC-V test work, ensuring corner cases and instruction behaviors are covered. Pragmatic and detail-oriented, he often surfaces subtle infrastructure or compatibility bugs that materially improve user experience in immersive web projects.
