• Involved in preparing the Detailed Design document for the project. Used Java 1.4 for the compilation.
• Used Spring Framework AOP Module to implement logging in the application to know the application status. Used Spring DAO Module along with Struts Framework to deal with Database.
• Spring MVC Framework IOC (Inversion of Control) design pattern is used to have relationships between application components. It is also used to separate the application configuration and dependency specification from the actual application code. Developed, and debugged the servlets and EJB with WebSphere Application server. Extensively used MVC, Factory, Delegate and Singleton design patterns.
• Developed the middle tier using EJBs, Java Servlets. Developed session, entity beans and message driven beans.
• Designed and developed the UI using Struts view component, JSP, HTML, CSS and JavaScript, AJAX, JSON.
• Designed the data flow for the client-side screens and the object interaction layer for the server-side components using Rational Rose. Involved in Use Case Diagrams, Class Diagrams and Sequence diagrams using Rational Rose. Involved in Code Review, Unit Testing and Integration Testing.
• MQ was used to provide a single unifying transport that reduces cost and maintenance efforts, including support for HTTP, REST and JMS. Used XML/XSLT for transforming common XML format and SAML for Single Sign-On.
• Designed configuration XML Schema for the application. Used JavaScript for the client-side validation.
• Used XML HTTP Request Object to provide asynchronous communication as part of AJAX implementation.
• Designed and implemented Java Classes to use JAXP parser to create Java objects to be able to modify the data received in the response. Junit tests were written to test each module in the application.
• Handled Java multi-threading part in back-end component, one thread will be running for each user, which serves that user. Used SOAP for Web Services by exchanging XML data between applications over HTTP.
• AngularJS takes another approach. It attempts to minimize the impedance mismatch between document centric HTML and what an application needs by creating new HTML constructs. WSDL was used for publishing Web Service interfaces. Wrote Ant Scripts to automate the build and deploy process.

Environment: Core Java/J2EE, Servlets, JSP, Java Spring, JSTL, EJB, JMS, XML, XSLT, JDBC, AJAX, IBM WebSphere Application Server 7.0, Oracle 10g, WSAD, IBM MQ, HTML, CSS, JavaScript, Eclipse, UML, Rational Rose, Windows XP, CVS, JUnit, ANT, Adobe Flex, Visio.

Java Developer

Responsibilities:

• Prototyped, designed and developed CCIS application framework complying with SOA architecture. This was reused in many of new applications/projects in CCIS department significantly reducing time/cost.
• Created MULE ESB artifact and configured the MULE config files and deployed.
• Used Angular JS for client while server validation through Expression Language.
• Built, published and consumed REST web services supporting both XML and JSON to perform tasks such as appointment cancellation, technician job management for Dispatch Tech IVR and Call Reduction modules.
• Developed SOAP web services for TSG UI and Outage Board applications.
• Used JAXB for marshalling and unmarshalling of Java objects to XML and vice versa.
• Used SOAP UI tool for testing and Liquid XML editor to validate XML documents against XSD's.
• Used jQuery, Angular JS, JSP, JavaScript, HTML, CSS and JSTL for the frontend modules of Tech IVR
• Provided the support for integrating the RESTful web services with clients
• Performed unit testing using JUnit and Integration testing using IVR system.
• Involved in creating Restful web services using JAX-RS and JERSEY tool.
• Developing the orchestrating of service through ESB calls to provide API's to the service portal.
• Applied OO design concept and design patterns such as DAO, Singleton, Factory, Business Delegate and Service Locator to improve the existing Java/J2EE based code base.
• Re-architected, refactored, and performance tuned a WebLogic and J2EE based CCIS call Reduction application, which previously came down almost daily, became a true 24x7 application at CCIS.
• JBOSS ESB development and providing necessary inputs to the service portal.
• Multitasked by gathering business requirements from user, duration and feasibility of requests and working on other projects by resolving issues.
