I brought Stephen in last minute for a project after our other resource fell off. He was professional, fast and his work was solid. Really helped our agency deliver to our client. He is now our main go-to developer.

Stephen has been very clear in his communication and timelines towards project production. He is very easy to work with and has done a great job with our website, I would happily recommend him.
