I’m Raiko Eric Koosaar and I currently work as IT Consultant at OCS Consulting plc in London, focusing on Infrastructure technologies and services. I have a passion for Exchange, Lync and Virtualisation.
I’ve always felt a little restless. So after living and working in Estonia for years, I thought, it was a good time to move on. I decided to move to UK and seek new challenges. I am always interested in new contacts and opportunities, so please feel free to contact me!

Blogs background:
I have been pondering about blogging for a while, but always managed to get stuck with the same problem.
What should I write about? I finally have an answer – It will become a Knowledge Base, a centre of information for myself. Problems, observations, notes, links etc. everything that might be useful, whether it’s Microsoft’s technology or Open Source.
