Get The Guru worked on my project leading on network design and implementation. This was a large, 2-3 year project delivering a new platform. The network was the largest component of that platform in both cost and complexity. They were also involved a lot in supplier management and providing support to live service teams.
They are incredibly knowledgeable, unparalleled in my experience, and clearly work hard outside of work maintaining an up to date knowledge of networking technology. Jamie was an essential member of the project and before long became an essential member of the wider programme and customer department, in my view.
There are very few people like Jamie out there.
