Tom Coupland discusses some of the various technologies investigated, and in many cases deployed at Nokia including Gradle, Spring, MongoDB and Clojure. Filmed at qconlondon.com.

Tom Coupland is a Senior Engineer at Nokia Entertainment Bristol. After years of Java, he set out to find more productive and elegant tools, currently very much enjoying spending time with Clojure. When not trying to make his bit of the world of software a better place, he can be found out in the real one, running, preferably in the mud, wind and rain. Twitter: @tcoupland
