James is an exceptional developer with the utmost attention to detail. His interest in bleeding edge techniques always sees him pushing boundaries and best practises on what it actually possible. Coupled with the ability to write high quality, testable code makes him an asset to any team. He has a wide range of knowledge from server to the client side in various languages (as well as system admin), and has recently developed a strong interest in Node and Angular - picking them both up very quickly to a very high ability. I would happily work alongside James again - and hope to do so in the future.
