• Involved in various phases of Software Development Life Cycle (SDLC) of the application like Requirement gathering, Design, Analysis and Code development. Agile Methodology is used for development of the application. Generated Use case diagrams, Class diagrams, and Sequence diagrams using Rational Rose.
• The application is designed using J2EE design patterns and technologies based on MVC architecture.
• Used J2EEdesign patterns like Value Object Pattern, Session façade, Singleton, Factory and DAO.
• Spring with Tiles Framework is implemented for a common look in all the presentation views.
• Integrated struts MVC with spring DI and Spring hibernate DAO. Used SVN for version control of the application. Developed to provide RESTful API utilizing Spring Boot with Spring MVC.
• EJB Session Beans were used to process requests from the user interface and CMP entity beans were used to interact with the persistence layer. Developed EJB MDB's and message Queue's using JMS technology.
• Involved in writing XML validation classes using Struts validation framework.
• Designed the user interfaces using JSPs, AJAX and Struts Tags. Taken care of multi-threading in back end java beans. Implemented security for different front-end views based on the access privileges.
• Implemented complex back-end component to get the count in no time against large size MySQL database (about 4 crore rows) using Java multi-threading. Developed Junit test cases for DAO and Service Layer methods. Built Spring based Java and Scala Microservices to support Enterprise Web application.
• Handled Java multi-threading part in back-end component, one thread will be running for each user, which serves that user. Used XML Web Services using SOAP & Microservices to register agents using non-java application. Involved in writing DAO, DTO's using Hibernate DAO Support.
• Used JMS for the asynchronous exchange of critical data and events among J2EE components. Publisher-Subscriber method was used for data loading and Point-To-Point method of JMS was used for event processing. Used RAD IDE based on Eclipse for writing code for JSP, Action Classes, Struts and spring beans.
• Implemented persistence layer using Hibernate that uses the POJOs (which do not have the business processes) to represent the persistence database tuples. Used Log4J to capture the log that includes runtime exceptions. Used IBM WebSphere Application Server to deploy the application as like WAS LIBERTY.
• Developed the ANT scripts for preparing WAR files used to deploy J2EE components.
