    Mehdi R.

    Network Engineer

    United Kingdom

    Being an organized and disciplined person, I have a passion for system optimization, automation and orchestration. When I see all the systems are optimized, up and running, that is the day for me to celebrate. That is my motivation to look for new solutions and ideas to make my job easy and run my organisation's infrastructure flawless. As long as there is a problem there should be a solution for it and if you have not found the solution yet, chances are you are not looking good enough or you are looking at the wrong direction. Just be patient (but not lazy) and keep searching. ** I am the calm one who does not get frustrated and stressed under the pressure ** I am always in self-taught learning phase ** I look for new challenges otherwise I get bored ** Give me a system and I will make it run like a Mercedes
