John Kouraklis started exploring computers when he was 16 and since then has followed all the way from Turbo Pascal to Delphi and Delphi Tokyo as a hobby initially and as a profession for most of his adult life. He has developed a wide range of applications, from financial software to reverse engineering tools, including an application for professional gamblers.
He is part of the Delphi community and participates in online communities, forums, and many other events. For example, he is active on Delphi Praxis, which is perhaps the biggest English-speaking online forum about Delphi. John also has a personal website where he posts articles regularly. Lastly, he has written two books about Delphi published by Apress.
