Rockstar

Zeyu Yang is a Founding Software Engineer with a decade of hands-on experience building complex front-end systems and node-based back-end features, now based in Mountain View. He specializes in React and Node.js, driving product-quality UI and runtime integrations across startups and OSS projects—from maintaining LlamaIndex frontend tooling and Maskbook’s browser extension to contributing bug fixes and type-system improvements in high-profile repos like Node.js and Vue.js. As an early engineer and maintainer on multiple projects, he combines shipping polished UIs (BlockSuite, AFFiNE) with lower-level runtime and tooling work (Rollup/PostCSS, Node core), often improving type safety and cross-runtime compatibility. Notably, he builds privacy-first and collaborative apps and has repeatedly taken projects from pre-alpha to stable releases, reflecting both product instincts and infrastructure discipline.
