It would be a pleasure to work with him again in the future and I wish him the very best. - Cherie Watts, colleague at Red Bee Media, UK
Nick is an experienced and highly qualified network engineer who did an excellent job at CSL during his brief tenure. He was responsible for the elaborate planning and implementing of the new SMILE system for CSL's internet services. On top of that, he was able to share his knowledge and expertise with a team of local engineers and make substantive improvements to CSL's internet infrastructure and internal network. Nick is a matured professional whom you can count on to finish a difficult task. His practical approach and management expertise was very much appreciated by the senior management team at CSL.

I worked with Nick for 2 years, and found him to be a first rate engineer. His depth and breadth of technical knowledge was excellent which meant he could drill deep into complex networking issues which required a thorough understanding of the topic. As well as this work ethic, and attention to detail were beyond reproach. This meant that Nick was always the person I turned to when I had the more "interesting", or taxing problems to solve. On top of that, (and of almost equal importance), I always found him a pleasure to deal with. - Ian Salt, colleague at Red Bee Media, UK
