• Participated in a team to design the framework of a management system employing cutting-edge front-end technologies such as HTML5, CSS3, and Bootstrap. • Through Test Driven Development (TDD) and Agile Estimation and Planning, I was able to significantly improve code quality and efficiency.• Deploying and maintaining production environment using AWS EC2 instances and ECS with Docker.• Designed and documented REST/HTTP, SOAP APIs, including JSON data formats and API versioning strategy.• Tables were created using HTML5 and CSS3 to display customer order information, and JSON data parsing wasperformed using REACTJS to present information on tables. Migrated SOAP web service resources to Spring RESTful web services resources using Spring REST API with Spring Boot.• REACTJS components such as modules, directives, controllers, filters, services, and APIs were used to create a Single Page Application (SPA), customer information arrangement, and product classification, among other things. • Virtualized servers in Docker as per test environments and Dev-environments requirements and configured automation using Docker containers and Used Microservices architecture, with SpringBoot based services interacting through a combination of REST and SpringBoot.

• Used Amazon Cloud Watch to monitor AWS services and Amazon Cloud Watch logs to monitor application.• Front-end development of Single Page Application (SPA) for Voice platform in Angular 5 framework and later updated the applications to Angular 7 and then Angular 8.• Utilized AngularJS for consuming a RESTful web service using AJAX services like http, resource and handled cross domain requests to retrieve the required JSON data for the application.• Experience and proficiency in developing application using Angular, Node.js, Express.js, MongoDB and other supporting JavaScript frameworks. • Built AngularJS framework including MVC architectures, different modules, specific controllers, templates, custom directives and custom filters. • Handled UI with AngularJS (MVC framework) to control the page layout. • Built Web pages that are more user-interactive using JavaScript and AngularJS. • Used AngularJS framework where data from backend is stored in model and populated it to UI. • Extensive experience on client-side frameworks like AngularJS and Jasmine Unit Testing. Involved in writing Java API for Amazon Lambda to manage some of the AW’S services.• Working Knowledge in React JS and working with React Flux architecture.• Developed client-server application using socket programming methodologies

• Developed the Object-Oriented Analysis & Design approach for the project using object-oriented paradigm throughout life cycles.• Responsible for designing and implementing the web tier of the application from inception to completion using J2EEtechnologies such as MVC framework, Servlets, JavaBeans, JSP.• Developed the application using Struts Framework that leverages classical Model View Layer (MVC Model2) architecture.• Implemented Business processes such as user authentication, Account Transfer using Session EJB.• Implemented Hibernate for O/R mapping and persistence.• Worked on Creative Suite 3 and Creative Suite 4 for creating websites and presentations.• Involved in the components styling (CSS) and skinning.• Involved in multi-tiered J2EE design utilizing Spring IOC and Hibernate deployed on WebSphere Application Server connecting to DB2 database.• Used Java Messaging Services (JMS) for reliable and asynchronous exchange of important information such as payment status report.• Developed JUnit test cases for all the developed modules.• Extensively used DB2 Database to support the SQL.• Used CVS for version control across common source code used by developers.• Used Log4J to capture the log that includes runtime exceptions.• Worked on event – driven modeling like Node.js for lightweight and efficient runtime built.

• Created UML diagrams (use case, class, sequence, and collaboration) based on the business requirements • Involved in designing and developing dynamic web pages using HTML and JSP with Struts tag libraries • Used JavaScript for client-side validation and Struts Validator Framework for form validations • Implemented PL/SQL queries and used Oracle stored procedures, and built-in functions to retrieve and update data from the databases • Used Hibernate Framework for object relational mapping and persistence. • Interfaced with the Oracle back-end using Hibernate Framework and XML config files. • Used Eclipse for the development environment• Wrote JUnit test cases to test the functionality of each method in the DAO layer.• Used CVS for version control.
