Bio
Dimitris Gourgouras
John and I worked together in the Business Analysis department in Creta Farms. Despite being part of different teams, i was really happy to work with John, as i knew that he was willing to support with hard work and good ideas. Always being open minded and eager to learn , he used to act as business solotions leader, rather than user support.

I met John at Creta Farms where he was an IT administrator and I always wish to work him again in the future because he is one of most hard-working, dedicated and willing professional I have ever met. I don't have experience in IT sector but I am able to say that John had solved every problem I confronted with my PC and mobile quickly and efficiently even when I was on holidays! He is so fast and positive person that I never hesitated to ask for his help.
