Xiaorui Cui is a Machine Learning Engineer with a decade of cross-disciplinary engineering experience spanning machine learning, systems, and front-end development, currently based in Mountain View. She transitioned from a PhD in Materials Engineering into software roles at Applied Materials and Google before joining ByteDance, blending deep analytical rigor with production-grade engineering. An active open-source contributor, Xiaorui has notable Vue 3 work—refactoring core emit/event handling in vue-test-utils and building a "mini-vue" to demystify Vue 3 internals—demonstrating both low-level framework insight and pragmatic UI component engineering. She writes clean, maintainable TypeScript and Composition API code, with a track record of improving testability and developer tooling for UI libraries. Colleagues describe her approach as principled—consistent with her GitHub motto “坚持做正确的事” (insist on doing the right thing)—which shows up in thoughtful refactors and reliable integrations across teams.
