Are you guys using rails w/ graphql-ruby? Would love to see a blog post with more details about the backend implementation!

The post links https://github.com/github/github-graphql-rails-example - "a small app built with Rails that demonstrates how you might interact with our GraphQL schema."

This just shows that they've made use of a graphql Rails client; the GP asked about the backend which could be in a different language.
