Implemented new functionality, addressed bugs and security vulnerabilities in award winning software, Transaction Guard, used by many financial institutions to detect and prevent online fraud. The software is mostly Java based and consists of multiple components running in separate JVMs. Mainly worked on two of the components which are Struts 1 web applications used by fraud analysts and system administrators.Integrated the Spring Framework into these legacy web applications. Spring IoC and Spring Templates were used to implement several JSON REST apis. These apis were mostly CRUD operations for chart configurations used in a front end UI. Built front end UI that visualized current and historic system statistics as charts. Used jQuery and Bootstrap for the overall UI layout and controls. Initially Highcharts was used to render the charts. We later switched from Highcharts to Dimple JS due to licensing concerns. Directed development and bug fixing activities of a remote team of developers based in Bangalore India. Wrote functional specifications that were handed off to the remote team for implementation. Performed code reviews.Wrote unit and functional tests as part of development, bug fixing and addressing security vulnerabilities when appropriate.Wrote SQL scripts to upgrade database versions in patch releases.Created a VM image of a complete installation of TransactionGuard and it’s sister product IdentityGuard. This VM was used by sales engineers to demonstrate different scenarios that show how these products integrate.
