I was in the same boat a month ago. However, I accumulated content that I wanted to publish, without cluttering it with commercial stuff (e.g. on medium). Focus on writing was my only criteria. But most themes I found for Hugo, Jekyll etc. had too much layout. I finally settled for a stripped-down mkdocs (du.nkel.dev). Primarily because mkdocs has superior markdown code formatting extensions (superfences etc.). The only thing I am missing is easy integration of a self-hosted open source comment system.

Regarding the OP's website: Unfortunately, it feels too cluttered. Examples: Why the header line `Home / Blog / ...`? I can see this from the URL. Why duplicate the title? Why duplicate urls next to the icons (facebook etc.)? Too much space without any content. Links/Contact/Search.. all mostly uninteresting for the majority of visitors.. Yes, mkdocs has search, too. But I disabled it - no one will use the search function on a blog.
