John is a freelance developer and agile coach based in south east England. He started programming two years before his birth and since then has been unable to put a computer down. John has been working with Ruby since 2006, after many years spent wandering the wilderness as a sysadmin, perl, and occasional C developer. When not writing code, John organizes the Tunbridge Wells Developer Meetup in his hometown, gives talks at conferences, and thinks about things in too much detail.
