• Built a web-based application using agile development practices and also using Extreme Programming. • Designed, implemented and tested the Spring Domain Model for the services using Core Java. • Developed presentation layer using JSP, HTML, DHTML, CSS, AJAX, JavaScript. • Involved in implementation of the application using conventional design practices (SOA-Service Oriented Architecture, MVC-Model View Controller). • Responsible for communicating with End client to support the application and analyse the issue and fixed the issue. • Have worked on Oracle 10g database for storing and retrieving the application data. • Implemented procedures, packages, triggers, and different Joins to retrieve the database using PL/SQL, SQL scripts. Created DDL, DML scripts to create tables and privileges on respective tables in the database.

• Agile methodology was used to develop the application. Daily Scrum was conducted as a part of this methodology. • Used Spring modules for building the application based on different design patterns. • Performed Inheritance based ORM with tables to simplify the data in Hibernate. • Design/Developed UI screens, components using Angular JS directives, custom directives, making service calls. • Implemented Routing mechanism in single page application using angular ng-route module and routing provider services. • Developed Business logic with the help of spring dependency injections, make them as Spring beans using configurations and spring annotations. • Developed SQL queries and executed them by using Hibernate Template provided by Spring. • Implemented Spring based declarative transaction management as Spring Aspects. • Configured and build Asynchronous communication with JMS services with MQ Series. • Developed Message Driven Beans (MDB) components to manage backend transactions. • Developed HQL queries to retrieve data using Hibernate. The Data Manipulation operations were implemented using Hibernate Template provided by Spring. • Used Hibernate mapping annotations, interfaces to work with Database CRUD operations. • Developed various advice for logging, versioning and caching Spring aspects of the application. • Used caching mechanism of a database connection object for faster retrieval of data. • Consumed Web Services (REST) from the third party for authorising payments to/from customers and implemented those using JAX-RS. • Did Packaging and Deployment of builds through Maven scripts and integrated with Jenkins. • Test Driven Development (TDD) approaches were utilised and the test coverage was always maintained and validated using Clover and Cruise Control. • Used Ajax, JSTL and JavaScript in front end design. • Used Log4j for tracking the applications and SVN used for version control.

• Involved in writing JSP and JSF components. Used JSTL Tag library (Core, Logic, Nested, Bean and HTML tag lib's) to create standard dynamic web pages. • The application was based on MVC architecture with JSP serving as the presentation layer, Servlets as controller and Hibernate in business layer to access to MySQL Database. • Designed/developed UI with AJAX, HTML, DHTML and JavaScript for interactive web pages. • Wrote complex SQL queries, PL/SQL Stored Procedures. • Developing the business functionalities and exporting them as REST web services. • Used XML and JSON for transferring/retrieving data between different Applications.

• Used RAD 7.5 to develop, test and deploy all the Java components. • Performed client-side validations using JavaScript. • Develop (Specify, create, modify, maintain, and test) software component(s) which are part of the NGEN software project on assigned technology platform. • Developing scalable applications in a dynamic environment, primarily using Java, spring, web services and object/relationship mapping tools.

Involved in analysis, design and development of business use cases and system requirements. • DevelopedJavaAPI to collect metrics and configuration data from the underlying host server using Java and j-Interop. • Added JMX support to monitor agent's behaviour. • Provide the ability to obtain performance data from external devices that support active SNMP requests. • Authored rules that raise alerts for problems in the virtualized environment.• Used STRUTS 2 tags for front end application development. • Involved with Spring IOC and Dependency Injection concepts to integrate Hibernate Dao classes with JSF Action classes. • Worked on JMS for sending a message and Message Driven Bean (MDB) to receive the message for providing Asynchronous communication • Used as XML parser to parse XML document containing application configuration information. • Performed unit testing using JUnit framework and monitored the error logs using Log4J and fixed the problems.
