As a principal developer on Sony Europe's Broadvision platform I can offer extensive experience in Broadvision 4.5 to BroadVision 5.5 development.
The 4.5 to 5.5 versions were the pre Java versions that run on Javascript Server Pages. My experience on these versions covered the following core components including installtion, configuration and monitoring.
Broadvision One-to-One Enterpise

For those organisations that are still using the versions to Broadvision 5.5 - I can offer development and problem solving solutions that have been developed in a high profile environment. Please use the contact links on this site to discuss your requirements with myself.
