What Clients say about us

Edi was hired to set up and maintain our server infrastructure. He not only completed requests satisfying and in time, but also provided suggestions and new ideas often going beyond what was orginally ordered and discussed. I certainly can recommend Edi for business as a highly skilled system infracture level consultant. (Martin Lechner -- CTO and Project Manager at Mobilizy GmbH.)

Edi has great knowledge in the IS/IT industry, especially with automated hosting, server services and customer support. And in addition he is very helpful, patient and supportive when it comes to critical and customer related issues. I would always again like to hire Edi for this kind of support(Harry Timons --Program Manager "World Summit Awards" at International Center for New Media)

I know Edmund from his contributions to many Radiant extensions, and from a few e-mail conversations about them. He seems like a very nice guy, and has helped me out on several occasions without expecting something in return. I therefore recommend Edmund to anybody who is considering hiring him for a job.(Benny Degezelle -- Owner & webdeveloper, Gorilla webdesign)

Edmund is a personable knowledgeable IT expert who delivers on time great results.(Christoph Doppelmeier -- Infrastructure, Operations, Testing Manager bei Sony NetServices)
