PROFESSIONAL EXPERIENCE:

Confidential

Responsibilities:

• Installed and configured Jenkins on the development and QA servers and Implemented a Continuous Integration/Delivery Pipeline in Jenkins in which the source code is being checkout from github and the artefact is stored in Artifactory, deployed in tomcat (dev server) and AWS(cloud). Setup a Continuous Integration/Delivery pipeline which consisted of the following Items: Backend Unit and Integration Test, Code Analysis with SonarQube, Concatenation, Uglify, JSHint, Karma Unit test of AngularJS frontend code, Artifactory publish to repository server, deployment to AWS and end-to-end test with protractor.
• Installed and configured SonarQube in the dev server for Code analysis and integrated Sonar plugin in out Gradle build and Jenkins.
• Installed and configured Artifactory in the repository server and integrated Artifactory plugin into our Gradle build for publishing the artefact into artifactory in the Jenkins Pipeline.
• Architected, designed and implemented a SPA (Single Page Application) in AngularJS which consume JSON from a Spring MVC, using Spring Security to secure the Application.
• Implemented a security module in AngularJS which integrated with the Spring security in the backend with Authentication and Authorization.
• Designed and Setup the UI which is responsive so that it can be view in both desktop and tablet. Removed most of the JQuery dependencies by creating AngularJS directives like datepicker, pagination etc.
• Implemented a technique in AngularJS to load all the JSON data from the backend before routing to the next page to limit page flickering.
• Unit test all the frontend AngularJS code using Karma.
• Implemented End to End Integration test with Protractor.
• Intergrated third party module like ngProgress that creates a progress bar which is used in the app in case of lengthy operation and ngIdle which automatically logs user out of the application if the application is idle for a while.
• Implemented an AngularJS grid table which was reused in almost all the other modules. This grid allows us to load thousands of record without any issue. Also this table can filter the records, pagination to any page by entering the page number in the pagination input box, change the pagination page size by choosing from the dropdown etc.
• Implemented a document library in AngularJS which has a tree-like interface to facilitate navigation to the desire documents where clicking on any document opens a new tab.
• Implemented a Grunt build for the frontend, creating all the Grunt tasks needed for the build and pipeline.
• Implemented a Gradle build for the backend Spring project, create a Groovy script to call Grunt tasks in Gradle and integrated Grunt and Gradle build so that I can call the Grunt tasks in Gradle and use only one build tool in the Continuous Integration/delivery pipeline in Jenkins.
• Used IText and Spring MVC to designed and implemented a RESTful service which dynamically generates a PDF version of the recommendations page. Also implemented logic in Angularjs to print this PDF.
• Performance test the deployed application in AWS using Apache JMeter simulating about 500 concurrent login users from aa CSV file.
• Implemented and test business rules in Drools Guvnor which I deploy in the cloud. Implemented a soap-based web service to expose the rules.
