Involved in developing Webservice operations in Service Oriented Architecture (SOA).Analyze requirements with team, write High Level design documents, System Use Case, analyze risk factors.Followed agile methodology during complete SDLC process.Participated Agile/Scrum development and deployment teamsUsed Spring Framework 4.1for the application development.Responsible for Web UI development in JavaScript using jQuery, AngularJS, and AJAXUsed Spring for bean instantiation, annotations, controllers, request mapping to handle the webservice request and response.Involved in front end development using Struts, JSP's, JSF and JSTL.Used JAXB for marshalling and unmarshalling of work order, billing XML documents, and JAXP for processing.Developed RESTWeb services to make web service calls simple and easy for the client to access it with the help of standard HTTP URIs.

 Designed the Web application Using SpringMVC (Model View Controller) pattern to make it extensible and flexible. Analyzed, designed, implemented web based application using Java, JPA, JSP, Spring, XML, and SQL. Used Agile methodologies during the complete project life cycle. Helped in preparing the design documents like process flow, sequence, component diagram. Implemented DIM Web service using Spring Framework. Used Agile methodology XP for development using User Stories. Used annotations in the complete project development, webservices, MVC design. Used JMS for consuming pin verification, device connect disconnect messages. Used JPA as data persistence API for all the DAO, database operations. Generated Hibernate Objects, and used Hibernate ORM for SOTI Publisher application. Used Maven project management tool for build and deployment of the application. Used Spring quartz timer to load the DIM data base with device battery information on regular intervals of time. Developed Spring REST Web services for opening, closing the locker door webservice operations

 Involved in creation of Low Level Design including sequence diagrams and class diagrams to understand the existing architecture.  Involved in the integration of spring for implementing Dependency Injection (DI/IoC). Developed code for obtaining bean references in Spring IoC framework.  Involved in development of REST Web services using Apache Axis2 to extract client related data from databases.  Used JIRA issue tracker to file the bugs. Implemented Presentation layer using CSS Framework, AngularJS, Wire-framing, HTML5. Involved in writing Oracle PL/SQL stored procedures, triggers, views, joins.  Implemented JPA (ORM mapping tool) framework to interact with the database to update, retrieve, insert and delete values effectively.  Developed Apache Ant script to create war/ear file and deployed on the application server.  Primarily focused on the spring components such as Dispatcher Servlets, Controllers, Model and View Objects, View Resolver. Used Design Patterns such as singleton, Business Delegate, Session Façade, Service Locator, Simple Factory Pattern, Data Transfer Object.

 Implemented Different Design patterns like singleton, factory and J2EE design patterns like Business delegate, session facade, Value object and DAO design patterns. Used Spring Framework’s IOC Dependency Injection to inject Service Object using Service Locator Design Pattern into Action Classes. Used Struts tag libraries in the JSP pages. Developed a controllerServlet that dispatches request to appropriate Action Classes. Developed the application under J2EE Architecture using Spring, Struts, Hibernate, Servlets, Web logic and JSP. Used Java Persistence API (JPA) and Hibernate for performing the Database Transactions.  Used joinpoint and adviceSpring AOP modules for cross cutting concerns and IOC for dependency injection. Designed extensive additions to existing Java Web Application utilizing Service Oriented Architecture (SOA) techniques. Extensively worked on Spring Bean wiring, Spring DAO and Spring AOPmodules. Designed Graphical User Interface (GUI) for various WebPages using AJAX, HTML, CSS, JSF, JQuery and JavaScript. Implemented SOA architecture with web services using SOAP, WSDL, UDDI and XML. Identified and resolved programming issues, Servlets and EJB s performance tuning opportunities. Used JMS API for asynchronous communication by putting the messages in the Message queue. Consumed Web Services (WSDL, SOAP, UDDI) from third party for authorizing payments to/from customers.

 Used the light weight container of the SpringMVC Frame work to provide architectural flexibility for inversion of controller (IOC). Involved in the complete Software Development Life Cycle (SDLC) phases such as Requirement Analysis, Design and Implementation of the project. Used SpringFramework for dependency injection. Implemented and deployed several EJB (Session and Entity). The front end of the project is designed on MVC architecture using struts,Tiles frameworks. Involved in Configuring tiles-def.xml, web.xml and struts-config.xml according to the strut framework. Used LOG4J for error logging at the development box and used ANT for building the deployable EAR/WAR components. Used WebSphere Application Server for deploying various components of application. EJB’s were running under the hood of WebSphere container/server. Implemented Back office loan services and web applications using Session Façade, Service Locator, Data Access Objects, Business Delegate, MVC, Front Controller and Data Transfer Object design patterns.
