Designed and development of new applications and existing system enhancements for several complex projectsParticipated in requirements gathering and analysis to design coding, testing and deployment.Worked on Agile methodology including team-based design and code reviews.Provided system troubleshooting, customization, and user training.Used agile methodology to develop user interaction forms and created use cases and sequence diagrams to assist in application design.Core Java with Concurrent API is used extensively for parallel processing and chunk processing.Spring is used for dependency injection (DI) and Hibernate framework is used for persistencyDeveloped generic component, which pulls product information from ESM system in XML, format and serialize to Object. This component developed using Java, EJB and Castor Framework.Thread pool and blocking queues used for parallel processing.Extensively used Spring JDBC, Spring AOP, Spring Remoting, Spring Schedulers.

Involved in Analysis, Design, Development, UAT and Production phases of the application.Designed and developed the application using agile methodology and followed Test Driven Development (TDD), Scrum.Developed all the UI pages for customer care application using HTML5, CSS3, Typescript, JavaScript, jQuery, Ajax. Node.js and JSON, AngularJs.Extensively worked on both consumption & producing of RESTful based Web services using JAX-RS & jersey parsers.Implemented the project as a multi-tier application using Spring MVC, spring boot, Micro services & used core spring concepts like AOP, IOC.Expertise in Core Java with strong understanding and working knowledge of Object-Oriented Concepts like Collections, Multi-Threading,Concurrency framework.Developed applications using the latest Java/ J2EE technologies and worked with the latest features of Java 8 and Java 7.Used Hibernate 3.0 ORM framework for persistence to database by integrating it with Spring framework using Spring Hibernate template.Used Spring Boot and developed the application as Microservices.Created custom directives to log the files in Event logger, Email logger in Angular JSCreated forms to collect and validate data from the user in HTML and JavaScript.Worked with clients to develop layout, color scheme for their website and implemented it into a final Interface design with the HTML/ CSS and JavaScript.Used JMS to place the import run requests into JMS Queue.Deployed the application on TOMCAT Application Server.Used Bootstrap and Angular UI to make the application user-friendly in the development of the Navigation bars, Tables, Sliders, Calendars etc.Implemented a Single Page Web Applications (SPA) based front end for displaying user requests, user records history and security settingsvarious users using JavaScript and Angular JS.

Involved in complete Life Cycle of the project starting from design to Testing the applicationPracticed Agile Methodology to keep track of the workflow tasks for every SprintDeveloped application modules using Spring MVC, Spring Annotations, Spring Beans, Dependency Injection and Spring AOP, with database interface using HibernateImplemented the application using Spring Boot Framework and handled the security using spring securityDesigned and developed web tier components and restful APIs using Spring MVC 3.0Implemented Spring Bean Factory to create proxy object using AOP FrameworkUsed Hibernate as an ORM mapping tool and worked with Hibernate Query Language (HQL)Defined the Hibernate Configuration File, Hibernate Mapping using annotation and created classes to persist the dataInvolved in implementation of enterprise integration with Web Services and Legacy Systems using REST and Soap Web serviceProduced and consumed the web services data in the form of JSON, XMLHave designed and built the new breed of Microservices for the client using Spring bootDeveloped classes using core java (multithreading, concurrency, collections, memory management) and some spring IOCExtensively worked on writing JUnit test cases for testing the business components developed in Spring and JavaUsed jQuery for front-end UI validations and creating dynamic HTML contentUsed AJAX Framework to create Controllers for implementing Classic JavaScript event handlers and implemented flexible event model for managing multiple event call backsDeveloped the interactive web pages using HTML, CSS, JSP, JavaScript, jQuery, and Ajax.
