As part of a geographically distributed development team, maintained and updated SOAP XML Web Services using JAX-RPC in Tomcat and EJBs in WebLogic. The Web Services provide access to a mainframe, a DB2 database, and multiple Oracle databases.Tools and technologies used: Java (JDK 6), Apache Tomcat 6/7, JAX-RPC, WebLogic 10, DB2, Oracle, IntelliJ IDEA, Enterprise Architect, CVS, Mercurial, Ant, Cygwin, UML, XML including DTD and XML Schema, SOAP and WSDL, Windows XP, Windows 7

Led a team of remote contract developers to implement SOAP XML Web Services using Apache Axis 2 with Tomcat and mediated through JMS queues. The Web Services provide access to a DB2 database. The team also developed an intranet admin-type Web site. Wrote a Java adapter to allow the Informatica ETL package to pass data records through the Drools rule engine.Tools and technologies used: Java, Spring, Hibernate, JUnit, Apache Tomcat, Apache Axis 2, DB2 UDB, Drools (JBoss Rules), JMS, Stored Procedures, IntelliJ IDEA, Enterprise Architect, Subversion, Ant, Cygwin, UML, XML including DTD and XML Schema, SOAP and WSDL, UNIX, Windows XP

Successfully implemented SOAP XML Web Services in Java EE, using WebLogic Web Services, EJBs, and servlets; the Web Services access a variety of data sources including SQL databases (DB2 UDB), other in-house Web Services, and other in-house systems accessed via TCP (sockets).Led highly successful reimplementation of the division’s major Web e-commerce product. Converted existing Web applications from WebLogic 5.1 to WebLogic 7.0 and later to WebLogic 9.1 with minimal disruption to ongoing development projects. Added XML Web Service interface to an existing Web e-commerce product. Extensively modified EJB business logic in one product to meet requirements created by a new large customer. Defined and managed the SCM project branching structure to facilitate parallel development projects.Tools and technologies used: Java, WebLogic Java EE (JSP, servlets, and EJB in clustered environment), WebLogic Web Services, DB2 UDB, IntelliJ IDEA, Together Control Center, Eclipse, XML Spy, Rational ClearCase (both UCM and Basic), Rational ClearQuest, Ant, Ruby, Perl, Cygwin, UML, Streamlined Modeling, XML including DTD and XML Schema, SOAP and WSDL, Solaris UNIX, Windows XP
