Ruby is primarily a language that I have used for building and scripting purposes, rather than deploying it onto a server. The primary framework through I built a number of static sites is middleman, which can be summed up as giving you the asset pipeline of rails (and immediate, easy access to using haml, sass, image assets, static data, whatever else you need) for projects that are built into static assets in development. I have also used jekyll for this purpose, but middleman is consideraly more mature and expansive in its options.

One major project for which I used middleman was UA’s unified accreditation report, in which case I generated a massive number of pages spanning many different embedded data presentations (some using react or other tools for reporting).

Over time, I have tended to supplant those tools with alternatives like gatsby (see: static sites), so ruby no longer represents a major factor in my work.
