• Exchange of data was performed using REST (HTTP), Web socket (TCP) and AMQP protocols. Google’ s POSTMAN was used to perform the testing of web services. Used JWT, Bearer Tokens and Oauth2 service for providing the authentication service.
• Developed the User Interface using HTML, CSS, JAVA Script, AJAX and Jquery.
• Used JAVA Script frameworks such as AngularJS while working with other existing GE based software.
• Performed unit testing of the code using Junit for JAVA based application and Jasmine Framework for client side.
• Used NPM and Grunt as the task manager tool for building the client side code.
• Github was used as Online repository. Used GIT as version control tool to check in, check out, commit, merge and update the files with regard to GitHub repositories.
• Extensively used Core JAVA concepts such as JAVA IO, Multithreading, Collections, Reflections and Networking.
