Senior Technical Consultant

GCC Innova

As the senior technical consultant I spend the majority of the time in customer-focused activities. These include 3rd level technical help-desk, onsite pre and post sales, project implementation and disaster recovery.

Design, implement and conduct customer based training in formal class room environments as well as training technical staff on a one to one or ad-hoc basis.

These are just a few of projects I have been involved with:-

Designed and implemented an IP Telephony system for Mitsubishi Air-conditioning six regional sales offices based on Zultys. This included creating a call centre for their spares and warranty centre in Manchester. 

Designed, implemented and installed a complete network for Monmouth School for Boys. This is a 'locked down" Microsoft 2003 network including Microsoft Exchange and Citrix Presentation Server for 300+ workstations making extensive use of Active Directory and Remote Installation Services to install and manage applications. This allows the characteristics of the workstation to change depending on the login and its location. A Citrix Presentation Server farm is used to isolate the students' dormitories from the main school network and to allow remote access via Remote gateway. 

Acted as a technical consultant for British Energy helping rolling out Citrix Presentation Server internally and externally for 1000+ users.
