Radu Costin P. is a Independent Computer Networking Professional. Colleagues describe him as "This guy is amazing! :) He strikes the perfect balance between business professionalism and a warm, easy-to-communicate-with person. He's one of the best trainers I've ever met and has one of the broadest understandings of technology in the IT domain. From Networks to Servers, Security to Voice Networks and going towards Cloud, Radu can architect a responsible and secure solution, train people on any of the topics and has the maturity and understanding to connect the technical differentiators to business impact. " and "Radu is in my mind the definition of a 'sysadmin'. First of all, he has hands-on experience of being a network and system administrator and can handle the responsibility of a rather large enterprise network. I have also seen him involved in a lot of community activities, especially in our local Cisco Networking Academy. And when something needs to be done, you can trust that he will get it done, even he needs to go the extra mile for it. He is very pragmatic and won't allow reckless ideas or actions jeopardize a project. But also not afraid of trying out new things on his own or if you come to him with rational arguments in favor of an idea. His wisdom of experience could help the team he is in to make the best decision for the present and for the future. You can learn a lot of things from him, and I know that in the years since I've known him, I have. Radu really likes the things he does and that makes him a great person to be around to both at work and off work."
