Oriented Architecture (SOA). The business supporting systems uses the CCT Application Development

Framework and CEBOL, an enterprise data bus; the Comet system, customer care web system and e-

commerce site; the Billing Engine system, invoice consolidation engine and billing system.

Designed and implemented the Common Enterprise Business Object Layer (CEBOL) architecture with

JBoss EJBs, with a JMS service bus, the entire backend system was written as sessionless EJBs, with

one MDB listening on SOAP calls over HTTP. The architecture further simplified and streamlined

development by staying with a simple architecture, but in the same time, it uses spring framework

and code generation to make it extremely flexible. Developers all like the architecture because they

can add new services to it in a matter of hours.

Designed and implemented the common web UI components using spring framework, JSF and

facelets with Ajax. Developers rapidly built web applications with the common components, using

them like lego blocks. State of the art AJAX interactions make the web applications very user friendly,

in the same time, developers do not write a single line of AJAX code, AJAX calls are handled by the

ajax4jsf framework.

Designed and implemented the web security layer with acegi for spring with CAS SSO. All of the web

applications do not implement security as the result of this security layer. Web application developers

only spent time coding business logic. The security layer is added later on to the application via spring

framework context with the ACEGI package. The security layer simplified web application development

and streamlined security functionality.

Lead for all the enterprise Web Services development. Oversaw all of the application developments

and directed the technical strategy for the entire backend application development team.
