    So I guess I can say my objective with the customer is to make their ideas a reality and introduce them to new ways of making their organization more efficient in both the virtual world and the real world. But my personal goal is to never let the technology get too far away from me, because if I do then someone else is going to take my place (and I’m sorry but I really like it in here SO IM NOT SHARING) If you want to know more about me visit my Website at: http://www.canadawebdeveloper.ca, http://dannymcguire.ardcorp.tv or http://goo.gl/NqtZz Note I’m working on my site at the moment so it will be offline for a while.. For this I have to say I been working with Microsoft and Google as an internal beta tester, I been called several times by Microsoft to join software, hardware and game developers to discuss some of the most important changes on the history of the company. And all this experience has told me that If I want to be the best at what I do, I cant just stop or be happy for having great feedback from customers or high executives, I have to push and push real hard to stay on top on technology, know it and master it before it even hits the light. Thanks Microsoft and Google for everything you have, and keep teaching me…  less
