はじめまして。#

山下生真 (Ikuma Yamashita) です。

日本のIT企業でインフラエンジニアとして働いています。

学生時代に機械工学を専攻しており、組み込みを中心に学んでいました。そこから派生して、システムプログラミング、Webアプリケーションまで趣味で作成するようになりました。レベル感としてはこのWebサイトが参考になると思います。

Rust というプログラミング言語が大好きで、様々なOSSにコントリビュートしています。

趣味としてデジタルイラストを中学生の頃から描いていました。また、このWebサイトにお披露目するページを用意しようかとも考えています。

皆様、どうぞよろしくお願いします！
