• Implementation of the design wireframe using Angular and creating services and exposing it to the backend which runs on Spring Boot. Here we also have another layer that makes use of NodeJS mainly used for authentication, authorization and session maintenance.• Developed UI application initially using Angular and made use of customized components.• Implemented customer side validations using Angular and created services on UI for storing and retrieving data from UI to the backend.• Was under migration of the project converting angular components and updating router Modules.• Developed key services for authorization and authentication in Node server, where we used LDAP. Later migrated the authentication from LDAP to Ping Access-SSO (Single Sign On) Application.• Involved in innovation of the current UI to make an implementation under mobile device access using cross platform technologies such as Ionic which helps in improving the business.• Involve in development, design and implementation of the front-end application using HTML5, CSS3, AJAX, Bootstrap.• Made use of Reactive Forms using Angular where most of the validation is done using component rather than using template-driven which provides in HTML.• Mainly involved in deployment activities CI/CD deployment and familiar with OSE (Open shift origin). Also made changes in Jenkins Files as per the requirement of the pipeline.• Worked on Kubernetes cluster as a part of deployment activity. Familiar with Open Shift commands mainly for deployment. Also created xml files for using a swagger API within UI.• Implemented JavaEE components using Spring MVC, Spring IOC, Spring transactions and Spring security modules.• Implemented transaction management using Spring AOP and used Spring Aspects for implementing logging functionalities.• Worked in integrating JMS with SPRING BOOT by providing an instance which is embed with Active MQ.•
