About Me
Gaetan has gained a solid experience over the past 13 years. His expertise spans across a large panel of network fields (WAN, LAN, WIFI, Datacenter, and Security). This expertise was demonstrated by the acquisition of the CCIE in 2016. But apart from his exceptional technical skills, his particularity is his ability to adapt to any working environment in a very short amount of time. This transpires through the large variety of companies (retails, factory, research facilities, banking, Internet operators, etc) where he was able to provide remarkable results from all his projects. This ability to quickly adapt stems from the large number of cultures that have influenced him over the years. He is currently fluent in French, English and Japanese. Allowing him to be part of your team is an insurance that your projects would be delivered with excellent results.
