I hired Christian for a project at Philips where we needed expertise in the field of (X)HTML, CSS, DOM, and ECMAscript, coupled with good communication skills to guide content authors in their work. He quickly became a valued member of our project, both professionally and personally. Christian is professional, skilled, communicates with ease about complex subjects, and is a nice guy ­čÖé

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.
