• Handled Java Multi-threading part in back-end component, one thread will be running for each batch which serves that batch.• Implemented Various J2EE framework Features like EJB, Struts, JSP.• Developed user interfaces using JSP’s, JSTL custom tags to support custom user interface.• Implemented Service Oriented Architecture (SOA) and web services using SOAP with JAX-WS, used SOAP for transmission of large blocks of XML data over HTTP.• Implemented Java 8 Features like Lambda Expressions, Functional interfaces, Streams to Migrate the Java 6 code.• Worked with Core Java concepts like Collections Framework, and Memory management.• Worked with different Interface connected with IES system like MMIS, IDES, BENDEX etc., generated required batch files required for them.• Worked with Elixir Server to create templates required for correspondence notices.

• Migrating existing application into REST based Micro services to provide all the CRUD capabilities using Spring Boot.• Used Spring Boot which is radically faster in building cloud Micro Services and develop Spring based application with very less configuration.• Made Services independent from each other by implementing Microservices concepts.• Building cloud Microservices and implemented back-end using Spring Boot.• Worked with Microservice architecture using Spring Boot to modularized code and implemented Rest API’s using Spring Rest and integrated Swagger API for documentation.• Implementation domain base classes providing basic properties using Spring Data.• Designed and developed RESTFUL web services using Spring Boot and Jersey framework.• Implemented Spring Cloud- Netflix ZUUL to building micro services for communication.

• Designed and developed web interfaces and business logic using Jakarta Spring Framework (MVC architecture), JSP, Servlets, Java Beans, JDBC, AJAX, Java Script, HTML, DHTML and XML Technologies.• Implemented the MVC pattern by using Spring with help of controller servlet. Action mappings, actions and global forwards are defined in Spring-config xml file and method call implementations are developed in Action.• Integrated Spring with Hibernate and used ORM tool hibernate to interact with database.• Migrating static web sites to Azure Design documentation• Used Hibernate for mapping java classes with database and created queries with• Hibernate query language (HQL) and integrated business layer with DAO layer.• Used Hibernate as an Object-Relational Mapping ORM tool to store the persistent data and for communicating with Oracle database and to customize the data for new applications.• Used Maven as build tool to build artifacts on the source code.• Implemented Multithreading feature for processing the multiple requests to achieve high performance.• Worked with Core Java concepts like Collections Framework, Multithreading, and Memory management.• Used Log4J to capture the log that includes runtime exceptions, monitored error logs and fixed the problems.

• The application is designed using J2EE design patterns and technologies based on MVC architecture.• Involved in various phases of Software Development Life Cycle (SDLC) and Agile methodology is used for development of the application.• Used J2EE design patterns like Value Object Pattern, Session Façade, Singleton, Factory and DAO.• Created Stored Procedures & Functions. Used JDBC to process database calls for Db2 Server database.• Involved in writing PL/SQL Stored Procedures, Functions, Triggers and Views for SQL database.• Developed back end interfaces using PL/SQL packages, stored procedures, functions, procedures, anonymous PL/SQL programs, Cursor management, Exception Handling in PL/SQL programs.• Implemented various features of Spring such as Dependency Injection, IOC, Annotations • Developed the application using Spring Framework that leverages the classical Model-View-Controller (MVC) architecture.• Implemented persistence layer with iBAITS-ORM.• Involved in designing the user interfaces using JSPs.• Developed JSTL custom tags to support custom user interfaces. • Used Eclipse for developing JSPs, Servlets with IBM WEB SPHERE server in the development phase.• Used Spring Security framework to setup authentication and authorization for the application using firm wide single sign on.• Implemented Service Oriented Architecture (SOA) and web services using SOAP with JAX-WS.• Used SOAP for transmission of large blocks of XML data over HTTP.• Involved in the development of underwriting process, which involves communications without side systems using IBM MQ & JMS.• Wrote Unit test cases using JUnit & Mockito framework.• Used ANT for automated build and deployment on IBM WebSphere.• Handled Java Multi-threading part in back-end component, one thread will be running for each user, which serves that user.
