Integration and Enterprise Architect

Responsibilities:

• Architecture and Implementation of Voice and Weblogic Portal Management for Customer access, Self Service, Intranet Portal for Internal Customer access. Seamless access to various billing and ordering system transparent to the customers (Core Java 1.6, J2EE, Weblogic 8.1, internal/external WebServices, Spring/Struts; Websphere 5.x/6.x,RAD 6.x/7.x, SOA, ESB Mediation and Orchestration (Mule/SeviceMix), C++, Solaris/Linux, db2), LDAP.
• Coordinate with Infrastructure team to set up Dev, Test, Prod Solaris/AIX Servers, HA, Load Balancing, Security.
• Confidential was built by gradual acquiring small as well as big entities. As a result, all the systems (billing, provisioning, ordering, etc.) are extremely heterogeneous, running on different platforms, written in different languages, and accessible through different protocols. Built Standardized SOA based loosely coupled interfaces among these systems (Services) by:
• Identifying Service Provided by each backend, with definition of exact Input/output using XML Schemas; transport protocols to access the services (Web Services, Corba, JDBC, Socket); service Implementations to accept incoming Soap XML, invoke the relevant application, extract the response, format it in the desired service data format. Service mediation is achieved through Mule/SeviceMix ESB. More emphasis on Core Java, SOA and Spring/Struts.
