Constantine is one of the founders (in 1985) of Greycon. Constantine was born in Greece and studied mathematics at Cambridge (BA, MA) and Control Systems at Imperial College (M.Sc.).

He is particularly proud that some of the code he wrote then is still in daily production use at many plants around the world, as part of Greycon's X-Trim.

He has also served as Deputy Director of the Industrial Systems Group at Imperial College. During 2010 he also consulted with the Greek Ministry of Finance, advising on how tax collection could be improved; the proposals were adopted a month later. In November 2013 he attended the 3-week Advanced Leadership Programme at Cambridge.
