Actively involved in the analysis, definition, design, implementation, and deployment of full Software Development Life Cycle (SDLC) of the project. Designed, analyzed, and developed the front-end and also back-end Servlets, Bootstrap for designing, HTML5, CSS3, Angular JS, Ember JS and AJAX, for developing presentation layers.● Worked on Java 1.8 upgrade using new library for refactoring, lambda, functional interfaces, streams -parallel processing and aggregations.● Developed application using Web Services for data access from legacy applications and integrated with new GUI developed using JSP, HTML, XML, Angular, Bootstrap and Spring Framework.● Involved in the development of DOM parsing, SQL procedures and in development of IVR in VXML, CCXML by using Java and JSP.● Involved in multi-tiered J2EE design utilizing Spring Inversion of Control and Hibernate.● Used Hibernate, Object Relational Mapping (ORM) solution, technique of mapping data representation from MVC model to Oracle Relational data model with an - based schema.

● Designed, analyzed, and developed the front-end and back-end services, Bootstrap for designing, HTML5, CSS3 and AJAX for developing presentation layers.● Developed various Responsive Single Page Applications (SPA) using REACT JS and closely worked with Application using React.JS and Node.js libraries NPM, gulp directories to generate desired view and redux to root the URLs properly.● Designed and implemented various NoSQL data models using MongoDB.● Involved in various integration and DevOps methodologies such as Docker, Kubernetes, Jenkins, Gradle, Jenkins File, Docker File and Elastic Search.● Implemented responsive UI which will scale itself depending on the device, plat form and browser, using React JS, HTML5, CSS3, Bootstrap and Performed client-side validations using JavaScript.● Monitored resources and applications using AWS cloud watch including creating alarms to monitor metrics such as EBS, EC2, S3 and configured notifications for the alarms generated● Worked on Test-driven development (TDD) and Behavior Driven Development (BDD) to generate JUnit test cases for testing various Java components.● Involved in writing Spring Configuration XML file that contains declarations and another dependent object declaration.● Performed UNIT testing with Junit and used Mocha and Chai for JavaScript framework and Cypress for e2e testing.● Used Aggregation in MongoDB to Match, Sort and Group operation.

● Developed the front-end by doing hands-on coding using semantic markup, HTML, XHTML, CSS, Java Script, and other front-end technologies as required by the program with a focus on usability.● Exposure to the Multi-Threading factory to distribute learning process back-testing and into various worker processes.● Designed Web pages by HTML and the query processing is done with the help of Servlets and JDBC.● Implemented Multithreading for handling multiple requests and for high performance.● Hands on Java full stack with spring boot, JPA, Hibernate, Spring cloud (configuration, Service discovery, Hystrix and Gateway).● Working Experience in Messing Platforms such as RabbitMQ, Kafka and AWS SQS.● Work with SQL queries to store the data in MS SQL Server.● Worked in Microservices like Sagas, CQRS, Service Discovery and Circuit Breaker Pattern.● Ensured tagging implementation is correct by walking through the code, working with digital pulse debugger and Charles web debugging proxy. Finally validate data quality by validating reports in Adobe Analytics and Ad-hoc analysis (Discover) tool.● Worked with development team to design solutions; implemented client-side JavaScript tracking code in JSP web application using s_code.js code library.● Designed and implemented applications using JSP, Spring MVC, Spring IOC, Spring Annotations, Spring Batch, Spring AOP, Hibernate, JMS, Oracle, and WebLogic server.● Created and optimized graphic prototype websites and applications interfaces using HTML and CSS.● Involved in writing application level code to interact with APIs, Web Services using AJAX, JSON and XML.

● Involved in all phases of the Software development life cycle (SDLC) using Agile Methodology.● Involved in writing Spring Configuration XML file that contains declarations and another dependent object declaration.● Inserted Dependency Injection between components using Spring (IOC) concept.● Used Multithreading (Concurrent) in programming to improve overall performance using Singleton design pattern in Hibernate Utility class.● Used Spring Security to provide authentication, authorization, and access-control features for this application.● Designed and developed Hibernate DAO using Spring Framework's HibernateDaoSupport and Hibernate Template.● Involved in creating various Data Access Objects (DAO) for addition, modification and deletion of records using various specification files.● Used MQ series of messaging and queuing purpose in the application● Created tables, triggers, stored procedures, SQL queries, joins, integrity constraints and views for multiple databases, Oracle using Toad tool.● Involved in Unit Testing of various modules by generating the Test Cases.● Performed configurations and day to day activities using WebLogic.● Involved in day-to-day handling of JIRA issues (production issues at time) that involved data inconsistencies that required to be solved in very less time.● Involved in Bug fixing of various modules that were raised by the testing teams in the application during the Integration testing phase.● Implemented PL/SQL procedures and views in Oracle Database using AltovaDatabasespy.
