    Network Engineers
    Martin is a very highly skilled and capable network engineer with a deep knowledge of all related technologies required to perform to the highest possible levels. Most importantly he has the ability to grasp the impacts to business operations of tasks he was asked to do and the issues he encountered and to leave no stone unturned in getting it right and getting it right quickly. It was an absolute pleasure working with a complete professional. I would have no hesitation in recommending him to any future employers and, in fact would engage him again in an instant should there be even the slightest need for his services
