Biography
中学生の頃にゲームサーバーのプラグイン開発に興味を持ったことをきっかけに、 2018年頃から Java
プログラミングを始める。
Java を学ぶ中で Kotlin に出会い、その簡潔さや言語設計に魅力を感じたことで、
プログラミングそのものへの興味を深めた。
プログラミングへの興味はサーバーの運用や自宅サーバーの構築にも広がり、現在は
Go、TypeScript、Perl を中心に、Web アプリケーションやインフラの設計・開発に取り組んでいる。
I became interested in developing plugins for game servers as a middle school student and
started programming in Java around 2018.
While learning Java, I encountered Kotlin. Its conciseness and language design appealed to
me and deepened my interest in programming itself.
This interest expanded to server operations and building home servers. I currently work
mainly with Go, TypeScript, and Perl on the design and development of web applications and
infrastructure.
