Amit Rathore has 10 years of software development experience, building mission-critical enterprise systems. He's the chief architect at runa.com, a targeted dynamic sale pricing service to online merchants. The system, written entirely in Clojure, collects extensive click-stream data from consumers browsing products, analyzes it using statistical models, and then offers the consumers special, personalized pricing in real-time. The system must handle extremely high-loads, and is written in a highly distributed, fault tolerant manner ideal for Clojure.
