The individual actively participated in agile (SCRUM) software development, contributing to design documents using Microsoft VISIO. For frontend development, they used HTML5, CSS3, JavaScript, Angular 4/6, and JQuery, implementing Responsive Web Design (RWD) with Bootstrap. Proficient in Angular 4/6 components, they built a library using Angular CLI and integrated packages like PrimeNG, Angular Material, and Bootstrap 4.As a Node JS developer, they created REST APIs and an inventory management web service. They utilized Spring for dependency injection, integrated with Hibernate, and implemented DAO using Spring-Hibernate ORM. Their work included WSDL creation, RESTful web services for XML and JSON, and continuous integration with Ant and Jenkins.They contributed to JUNIT test cases, unit testing with Mockito, and implemented logging with Log4j. Version control was managed using SVN, and they supported IST, QA, and UAT builds, deploying applications on UNIX for UAT and production. The individual showcased expertise in diverse technologies and practices throughout the software development life cycle.

The individual has experience in developing front-end screens using technologies such as Bootstrap, JTable, GSP, HTML, JavaScript, and CSS. They were involved in client-side validation, implemented applications using the MVC design pattern, and designed web pages with various technologies including Angular 2, Typescript, Ajax, and Bootstrap. The focus included creating a responsive UI and dealing with CSS for different screen sizes. They also worked with SASS for styling and dynamic behavior. Other responsibilities involved CMS integration, creating TypeScript components, developing RESTful web services with the MERN stack, using React-Routers, and setting up Kafka clusters. Additionally, they utilized Selenium for web-based test automation, hosted microservices in AWS, and employed Grafana for monitoring dashboards with data metrics from Splunk and MongoDB.

The individual has experience in designing and implementing Java/J2EE client applications using various technologies such as JSP, JPA, Struts, Spring, Spring Boot, Hibernate, and JSF. Their responsibilities include requirements analysis, technical design, implementation, testing, and documentation. They used Hibernate for backend persistence against an Oracle database, wrote JUnit testing classes for comprehensive coverage, and designed the presentation layer for bill comparison charts.Additionally, they integrated CyberSource Payment Gateway using SOAP WS for auto-payment flow, exposed User Profile services through RESTful WS, and participated in daily stand-up meetings following the AGILE process. The individual configured JMS Server and DB Connection pool setup, performed load balancing checks using JMeter, and automated web service calls with PostMan and Newman. They worked on SOA infrastructure, Ajax, jQuery methods for data retrieval, and cross-platform compatibility. The development process involved TDD, Scrum, and manual test execution with bug reporting in JIRA.

The individual actively participated in daily SCRUM meetings and weekly sprint meetings. They implemented UI components using AngularJS features, such as dependency injection, models, data binding, and controllers.
