With my background in Web Science I am well equipped to analyse user behaviour with scientific precision. I always take the users experience into account and tend to develop user-first.


Well hello there! I am Dennis Collaris, a 24 year old web enthusiast from Holland. Ever since I was young I was fascinated about the capabilities of computers and the internet.
