Shopify uses Sorbet and a few companion projects (e.g., Spoom [1] and Tapioca [2]) to manage Rails projects of various sizes. While there are some holes, like you find with any gradual type system, I think you'll find the experience is quite good. The awesome-sorbet [3] project has a comprehensive list of blog posts, conference presentations, and podcast episodes that dig into that deeper.
