Daniël Feijt

Software Engineer

My name is Daniël Feijt BSc and I am very proud to say I am the first official employee of CompleXYS B.V.! I studied Environmental Sciences at Wageningen University, with a major in Environmental Quality and Systems Analysis and my minor in Environmental Technology. However Computer Sciences peeked my interest and as such I am now working at CompleXYS as a Software Engineer.

Presently my main area of focus is research, developing and building the next generation commercial software tools and applications. For now my language of choice is C# but my skills and knowledge develop as we continue working on exciting products and solutions. I hope you will soon be able to experience the fruits of our efforts.
