We worked together about 3 years in the same department in several projects and incidents. Looking back it was always nice working with Christian because of his knowledge of the Linux Operating system and his positive nature. As well in normal working conditions as in situations where we’re working under pressure and with no direct sight on a clear solutions.

Working with Christian is a pleasure because of his knowledge of Linux, cooking, websites and because of his sense of humor. Together with his comfort to speak fluently English, German and French, makes him a versatile colleague.
