His skills have saved my life more than once. He’s a rare find: a sysadmin that really understands deploying Rails applications.”

Superb from both a technical and business angle, John makes everyone in the meeting room happy with his work. He will honestly, clearly and unbiasedly present all the best possible options, and then, if needs be, get his hands dirty on the command line - all at very affordable costs.”

He is a highly intelligent individual full of good ideas and supportive of people with whom he works. I look up to him as someone who is in possession of that rare combination of both talent and willingness to teach others.”
