About Me

I’m an Independent Consultant, who specialises in Unified Communications and Collaboration technologies, with a primary focus on Microsoft Teams, Skype for Business, Office 365, Azure and Amazon Web Services.

The Early Years…

I’m part of the 80’s generation that grew up with IT such as Personal PC’s (Commodore Plus 4..yes I had one), gaming consoles like the Super NES and the Megadrive, so was very familiar with technology. There was no internet back then, so life was very much offline and simplified. I must have been one of the very few who grew up with a home PC as I remember trying to install TCP/IP on my 486 SX with Windows 3.1 in a vain attempt to get Internet Explorer to work. Unbeknownst to me I didn’t realise I needed a network card a modem, telephone line, etc…Anyway I digress .

The Beginning….

Starting out as a helpdesk operative I have worked my way through first, second, third, and fourth line support, moving into engineering, then consulting & project delivery, while carving out technical expertise in all things Cloud & Collaboration, and have now scaled the lofty heights as a Consultant Architect.

This journey has allowed me to gain a large breadth and most of all in depth experience across many different technologies, ecosystems, sectors, public and private. As well as across businesses of all sizes from small to medium of less than a few hundred, to enterprises of hundreds of thousands of seats. Each with varying needs and differences but ultimately all of them had a common goal which was to acquire cloud & collaboration expertise to deliver solutions that enabled them to resolve a business problem using technology.

The Skype For Business Pro….

This is where I like to think I can add that extra bit of value as not only a problem identifier but a problem solver capable of identifying the business problem and providing the appropriate solution to resolve the business problem. At this juncture I could reel off a litany of qualifications, relevant industry expertise, and elaborate further as proof of this right? But I won’t as hopefully you’re now suitably interested to have a browse around my site and see that information for yourself.

“An often forgotten element of collaboration technology is the human collaboration required to deliver it” – Shawn Harry



There are many avenues in this current age of social networking to provide an Internet presence such as LinkedIn, Google Plus, Facebook, Twitter etc. However I decided to make a website that consolidates all of this and my online musings into one place that will hopefully be a bit more than just another Technical blog. So hopefully a bit like LinkedIn but on steroids with far more material and useful information about me and various things I’m working on in the field that may be of use to others. Hope you enjoy!


Some comments from those I have had the pleasure of working with.
