Brief Summary

I have over 30 years’ experience in the IT industry, most of which has been spent in networking/telecoms in the UK/EMEA and NZ/APAC.  I have worked in varied roles such as technical consulting, network design and architecture, pre-sales support, operational support and software engineering/development.  After moving to New Zealand in October 2008, I worked in several roles for over 13 years, before moving back to the UK in March 2022.

My experience has been gained in a wide range of organisations, from start-ups, through enterprises and to large service providers and telcos.  I have worked in both team environments and on an individual and independent basis.  In recent years, I have also done a lot of my work in the public sector.

My background has a strong hands-on element to it, and as such I get satisfaction from being able to test a design in a lab to prove that it will work before deployment in a production environment.  To back this up, I have over 25 years’ experience with Cisco’s IOS, routers and switches, as well as more than 15 years’ experience with Juniper’s JUNOS, routers and NetScreen firewalls.

I very much enjoy customer-facing roles since no two customers are alike, and so the variety this gives is always a challenge that I am keen to take on.  Taking part in in-depth technical discussions with customers forms a key part of being able to fully understand their requirements, which is essential to being able to deliver a successful solution.
