Sadly, it seems it is just hugo. He mentions hugo in a post[1].

He definitely is using Emacs for most of it. He authors his posts in org files, and uses ox-hugo to export to Hugo.

I do something similar for my blog, except Pelican is my backend.

Interesting. I think I must've seen the same post when he posted it. Nowadays I just use Pandoc to go from markdown (with extras) to html.
