Freelance Network Consultant – CCIE Routing & Switching

My name is Wojtek Siodelski and I am UK based freelance network consultant with a track record of leading multiple large LAN and Wireless LAN projects. I am CCIE certified with 15 years experience in networking. Personally, I am very driven and ambitious individual with remarkable attention to detail and strong leadership skills. I can lead large teams, run with design workshops and explain the most complex technical ideas in layman’s terms. My great strength is not only the network engineering but leading large and complicated technical projects, bringing everyone on the same page and taking full ownership and accountability for the final solution. Together with my colleague we have built another startup IT company called EDNX which provides various network consultancy services.

Interesting facts about me

In my spare time I am dedicated triathlete that always wants to improve his previous iron-man time. It is the challenge that motivates me both in personal and business life. When I was in my early twenties I was the youngest qualified Yacht Master in Poland leading one of the polish vessels in International Boat race – Tallships 2000. There is quite a more information about that on my old personal website. I have also started a business with my wife selling large wall clocks which is pretty successful worldwide. All of those wall clocks are handmade and hand painted by my wife and I am the main website developer.
