Responsibilities:● Performed Design, Development, Test, Validation, and Integration of the software.● Worked on system maintenance and enhancement requests that includes web development.● Used RxJS 6 of Angular 6 with the new methods and the new importing style according to the package structure change in Angular 6.● Implement the web application using Full Stack technologies (Oracle DB, Express, Angular 6, Node.js) along with HTML5, CSS3, JavaScript, jQuery, Bootstrap, and other web technologies.● Migrated the code from Angular 5 to Angular 6 by utilizing new commands provided by angular CLI 6 like ng update, ng add and implemented the multiple project support with angular, Json provided in Angular 6.● Implementation of the design wireframe using Angular 8 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 6.0and made use of customized components.● Implemented customer side validations using Angular 8.0 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. Implemented the complete set up with configuration file changes from Angular 6 to Angular 8.● 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.● Created sessions for Login user and setting session timed out for the entire UI application.● Strong understanding on client-side application and very good at attaining the architectural design for MVC using directives, promises and pipes.
