This blog is where I work with web development, infrastructure, and AI, archiving the knowledge and insights I gather along the way.

Posts are written in Obsidian-based Markdown, then hand-picked and
published here โ€” on a site I designed and built with Astro.

I also share posts about daily life and hobbies.๐Ÿชด

In the end, only the record remains! โ™ช(*ยดฮธ๏ฝ€)ใƒŽ
