This story starts out literally like a movie - millions of dollars on the line and the clock is ticking. We had a large dataset we needed to run expensive calculations on and our existing tools couldn't cut it. Clojure came to our rescue with its wonderful combination of simplicity and performance. But that's just the beginning. I'll also tell the tale of how our little Clojure script grew up. I'll talk about how we constructed our test suite, our experience refactoring Clojure, and the delicate art of introducing new developers to their first Lisp.
