PROFESSIONAL EXPERIENCE

Project Description:

Responsibilities:

• Responsible for the designing, coding and developed the application in J2EE using MVC architecture
• Developed the presentation layer using HTML, JSP and Servlets
• Used Unix shell scripting
• Developed Session Facade objects using Stateless session beans EJB 2.0 for having single point of control for a business service
• Responsible for development of DAO's Data Access Objects to interact with the database using JDBC
• Responsible for configuring WebLogic Application Server administration activities which involved creating clusters, Database Connection configurations, performance monitoring etc.
• Responsible for development of XML schemas
• Written Stored Procedures in Oracle
• Developed web services using SOAP and XML
• To provide a service-oriented architecture, a web services approach was taken, and Weblogic 6.1 was used as the J2EE application server. All web services were registered in a UDDI registry, described using WSDL. Java based client applications utilized JAXR and JAXM to connect to the UDDI registry and to send the SOAP based messages to the service.
• Used J2EE, Java, JSP, Struts 2, and Ajax, JSON, PL/SQL, XML, Hibernate, spring, JavaScript, Apache and Tomcat technologies. Participate in team estimation and proposed the possible solutions
• Responsible for Production support of Application by proactively looking at production issues
• Used Log4j to implement logging facilities
• Used MS-VisualSourceSafe for version control for software configuration management
