Software Engineer/Architect

Working on design an implementation of a Batch Processing framework to manage processing of complex batch files, and file formats, and to interface with a Debt Management system running in an IBM Websphere Application Server environment. The system used a J2EE architecture with server-side session management (using components such as Spring, Hibernate and Session EJBs). The client-side batch framework made heavy use of XML/XSL transforms, and java reflection, to generalize handling of the different batch files, and used JMS and EJB interfaces to interact with the server-side components.
