It is a reinsurance application. In this I worked on the enhancements and maintenance of the existing application. We will get the defects or enhancements accordingly we work on it. Also worked in writing test cases for nightly jobs using groovy and created Jenkins job for those. And worked on performance improvement for the JSP files. As part of performance improvement, we migrated all the java codes written in the jsp file to java classes. It will be helpful to identify the issues by debugging before it was difficult to identify. Written test cases for the java classes.
