Summary
🤩
Rockstar🎓
Top SchoolJanine Liu is a Software Engineer with seven years of experience specializing in 3D geospatial systems and tooling, currently contributing to the Cesium open-source ecosystem. She bridges engine-level plugin development for Unreal (cesium-unreal) with backend data processing (cesium-native), shipping changes from collision handling and performance-focused refactors to a PNTS-to-glTF converter and unit tests. Her work on the flagship Cesium projects also includes 3D Tiles 1.1 support and metadata/renderer refinements that improve format compatibility and runtime behavior. That blend of Unreal Engine C++ plugin expertise and backend format-conversion chops makes her effective at connecting game-engine workflows with web-scale geospatial rendering.
