Bio
Geert Valk
I've worked with Sebastian for about 1,5 years at Liberty Global and found that he is a very knowledgeable, flexible and hard working professional. With difficult technical issues he has proven to come up with creative solutions. He's always willing to help, even if it means moving outside of his comfort zone. By showing this kind of behaviour he managed to bring multiple projects to a successful completion. It have been a great pleasure to work with him.
