@jujes and @flip-bs, thanks for your interest in the theme of my site! It's not currently available as a hugo theme (it's mostly handwritten), but I'll look into making it available as a theme (no promises!)
@jujes and @flip-bs, I've written a blog post which describes some aspects of the theme of the site, as making it available as a full Hugo theme is not a priority for me right now. The blog post should be sufficient to get you started on making your own site. Good luck!
