Welcome

I've updated this website since I was a high school student. It has been hosted at

1. Yahoo!ジオシティーズ(opens in a new tab)
2. infoseek isweb(opens in a new tab)
3. land.to(opens in a new tab)
4. @PAGES(opens in a new tab)
5. 000webhost(opens in a new tab)
6. Amazon EC2(opens in a new tab)
7. さくらVPS(opens in a new tab)
8. Amazon SAM(opens in a new tab)
9. Cloudflare Workers(opens in a new tab)

My programming skill has developed along with the website.

I rarely update any contents, ever since I started a career as a professional web engineer. However, I sometimes come back here and feel nostalgic memories.
