Profile

As a Technical Consultant, I am authoritative on medium and high-end UNIX systems design and configuration. With deep and wide knowledge of operating systems, servers, storage and clusters, as well as LAN, SAN and Virtualisation, I have the knowledge and understanding to propose, design and configure high-end systems within multi-million dollar projects. I bring high levels of professionalism, commitment and attention to detail to every project. I match customer requirements with industry best practices to deliver a design and implementation which provides the best of both.

As solutions do not end with a design, I also have excellent troubleshooting skills to address any issues which may arise later on in the project lifecycle.

UK Government & Defence Security Clearance (SC) valid to January 2018.
