This was a support role, which involves assisting both an administration team and a customer base in troubleshooting problems with their devices and problems with software applications used in conjunction with the devices. Some of the application troubleshooting involved resolving errors that have occurred during installation or use of the software, and also driver installation and configuration issues. This role allowed me to apply my knowledge of troubleshooting systems and find ways to resolve new issues that arose. During the last 6months in this role I was given the opportunity to work alongside the IT department on a part time basis, assisting them with day to day tasks, as well as covering a member of staff's role in the department whilst they were away. This allowed me to develop my IT skills whilst still performing technical support tasks.

Haven Networks is a small business venture I co-run with a colleague, set up shortly shortly after I finished at Maplin Electronics. Haven Networks provides a broad range of services including web design, computer maintenance and technical support. Although still active, new clients are limited to friends and family. Running Haven Networks gives me the opportunity to experiment and improve across a broad range of transferrable skills, including running a business, self-motivation, customer relations and technical skills such as web design.
