ABOUT.ME

I build software and developer tools with a focus on things that are useful, clear, and actually runnable.

My primary languages are Python, Kotlin, JavaScript, and TypeScript. I also work across systems, data, shell, functional, hardware, blockchain, formal-methods, and legacy ecosystems. I use that range to choose the right tool for the problem instead of forcing every project into the same stack.

主にPython、Kotlin、JavaScript、TypeScriptを使いながら、システム、データ、シェル、関数型、HDL、ブロックチェーン、形式手法、レガシー系まで幅広い言語・技術を扱っています。

Godot 4 入門

Technical Review / Verification

Technical verification for “手を動かして学ぶGodot 4 入門 — Unity経験者のためのハンズオンガイド(C#版)”. Verified the manuscript workflow end-to-end and helped isolate environment-specific issues before publication.

Godot 4 / C# 技術書の制作に協力。原稿に沿って全手順を検証し、環境依存の事象の切り分け・確認にも参加。2026年9月Kindle出版、奥付に制作協力者として掲載。
