Prior to joining Camelot, he worked at International Business Machines Corporation (“IBM”) (NYSE: IBM) for more than 19 years. He joined IBM as an associate partner in 2002, and was promoted as a Vice President of IBM in 2011. During his employment at IBM, he successively served as an associate partner from 2002 to 2005, a partner from 2005 to 2011, a vice president based in Beijing from 2011 to 2014 and a vice president based in New York, the United States from 2014 to 2016. From 1997 to 2002, he successively served as a consultant, a senior consultant, a principal consultant, and a director at PriceWaterhouseCoopers before PwC Consulting merged with IBM in 2002.
