Mark joined this £50m central government project as an integration specialist to develop a large number of interfaces. This implementation was required to process sensitive data and consequently all staff required security clearance in order to work on the project.

The data being handled by the implementation was granted different levels of security classification resulting in two different Siebel implementations being developed, each one handling the data at the different levels of security classification (Restricted and Confidential). This also meant that a large number of interfaces were required to transfer information between the two Siebel solutions as the security restrictions meant they had to be physically separated.

Additionally, most of the user interaction would be carried out via a separate web front-end, requiring even more interfaces to manage the information transfer between Siebel and the web application.

Oracle's SOA Suite was used as the middleware for all interfaces, whether between the two Siebel applications, the web front-end, or any other third party systems.

Mark's role on this project was to develop a large number of these interfaces using Web Services. Configuration of the base application was also required to support the data being managed by the interfaces, but also to allow administrators and a small number of general users to manage the data directly in Siebel. Marks extensive Sebel knowledge also enabled him to offer advice and assistance to other members of the experienced Siebel team.
