I've been slowly piecing something like this together for myself using jekyll. I'm not familiar with the tools you're using, but the demo site looks very nice. Good job!
Are there other examples of turnkey self-deployed sites like this?
I'm actively developing my personal site which is built with elixir and phoenix. That said if you are looking for an out of the box solution I would stick with simple and go with a static site generator like you mentioned or possibly Wordpress.
