John F. Doyle is a Customer Engineer at Microsoft. Colleagues describe him as "During the time I worked with John, he was always available, and was able to deal with any issues that cropped up quickly and effectively. He excelled in being approachable and responsive to all levels of staff, no matter what else was going on around him. Despite the odds, we completed an Exchange migration within the timescales, and within budget (and a lot cheaper than what certain consultancies were bidding at!). I hope our paths with cross again in the future." and "I find John to be experienced, technically astute and easy to work with. He's a smart guy and a sought after project team participant."
