Graduate, IT
Wim is really one of a kind ...
Punctual, keeps his promises, works very fast and efficient.
For the set-up of our websites for client working with Fortissimmo, I always rely on Wim, simply because he is a very trustworthy and thoughtful person.
As I think of Wim, I think on dedication, enthusiasm and a lot of knowledge!
It's a real pleasure working with him.
Wim is a program- and web developer who is not satisfied with the status quo. He will challenge partners and clients alike to create new and surprising interactive experiences. Besides that Wim is a very likeabale guy, highly motivated to take every online job to the next level. I would recommend Wim for any IT job and would love to work with him again.
During the short time I was working with Wim, I noticed quickly that the knowledge of Wim is very broad and profound.
Our cooperation was focused on the handover of the project by Wim to me.
during the handover, I noticed the very high level of communication skills of Wim.

Too bad our cooperation at TelelinQ was so short and I hope to be working with Wim in the future
Wim is very professional and his technical and analytical skills are excellent, good communication, teamplayer, thinks always in solutions to improve business processes.
