He has been behind Sungard's international expansion, which saw grow revenue from US$2.6bn in 2002 to $5bn in 2010, as well as its move to private ownership in 2005, which he said "was the best strategic move in the company's history".

He previously served as CEO of BISYS Group, another outsourcing services provider from the financial services industry.
