Rockstar🎓
Top SchoolYuta Hiroto is a Vice President of Engineering and JavaScript specialist with 16 years' experience building and optimizing web platforms and developer tooling from Japan. He combines executive engineering leadership at Yuimedi with deep hands-on open-source work as a committer on webpack and a core collaborator on Node.js, contributing to performance-focused refactors, URL module features, and expanded test coverage.

Colleagues rely on him for pragmatic, test-driven improvements and rare cross-cutting knowledge that connects build systems, runtime internals, and application-level concerns.
