Vue.js core team / Vue.js JP core staff / Vite+ core contributor / chief engineer at @mates-inc
Based in Tokyo, working as a software engineer and chief engineer at @mates-inc. Most of the day-to-day work lives around frontend architecture, product design, developer experience, and performance tuning.
Also active on the Vue.js core team, with early work on Vue Vapor. Also active as a core contributor to Vite+ and continuing community work through Vue.js Japan User Group as core staff, alongside events, writing, and education.

About wtrclred
wtrclred is short for "water colored". The idea is to talk about technical subjects without stripping away texture, rhythm, or softness.
Accuracy still matters first, but the writing aims to feel like paper and ink rather than a sterile document. This site is both archive and record for that balance.
Selected Work
Picked from npx ubugeeei and intentionally kept short.
A minimal Vue.js implementation and online book for learning the internals by building them.

A reading notebook and book for understanding the Vue Vapor implementation from source.
Framework-agnostic documentation tooling built around a fast Markdown parser.
A personal Vue style guide capturing engineering preferences and implementation habits.
