I created and updated various type declarations for libraries, including dayjs bundled plugins and material-ui.

I'm currently (at 08/2021) investigating on vscode / TypeScript completion lag and high CPU usage while editing of material-ui, emotion and React. It requires diving into TypeScript's type inference code. At least one of the causes which I found became issue & pull request to TypeScript itself, which halves CPU time of material-ui / emotion in specific situation.

But because my 3-years-old 👶 is currently 🏃 😊 💥 💥 👫 😱 😭 😫, I squeeze time and motivation for that by hiring babysitter, exhausting my (full-time working) wife (:pray:...) or using holiday / midnight. So I really appreciate if you could sponsor me.

I'm also working on two non-profits (education (paid) and LGBTQ (free)) as pro bono.

型ファイルを書いたり直したり、最近だとmaterial-uiなどでvscodeの補完が詰まる問題をTypeScriptレベルで調査・修正したりしてますが、とにかく育児が忙しく、ベビーシッターをお願いしたり土日や夜中に作業したり妻にワンオペを押し付ける形になったりしてるので、スポンサーしていただけるととてもうれしいです！ 🙏
（$10の人が15人くらいいるとベビーシッター1回お願いできる分ぐらいになります。）
