Reading this I was concerned that it would be written in Ruby. While Ruby is a reasonable language for server development, it has almost no data science community when compared with some other ecosystems. I was very glad to see this is Python! Python has some of the best data tools out there, and a mature ecosystem for solving all the engineering problems that go along with a great data stack.
