I have worked on several projects for various clients and unfortunately not all are customer facing. The non-customer facing sites where either internally used or as part of a privately accessible network (client IP is allowed through the proxy). The customer facing sites are shown below:
http://www.sfgateway.com : Forum for Sci-fi enthusisaists
http://www.sf-encyclopedia.com : Sci-fi Resource
http://www.ageuk.org.uk : Customer facing portal for information on the company
http://mazda.co.uk : The official site of car company Mazda
http://www.mazdamotors.eu : Customer facing portal for information on the company
http://glassbusiness.co.uk : The official site of car registration and pricing
