Sometimes we wonder whether the blood in his veins has been replaced by ice. Always cool and relaxed, even though he has to deal with some pretty complex problems. We're talking about Tarkan Aslan. Extremely helpful and flexible, always willing to help clients. And we mean really help them, proactively, often before the client will ask. Very occasionally the ice suddenly melts. For example when Tarkan finds out that a ‘colleague in the market’ has not treated its clients properly. Tarkan does not like that, to put it mildly. But mostly… very relaxed. Someone you wish the best for. For example, ‘his’ system on the roof of the new airport in Istanbul.
