Confidential, Sunnyvale

Technology Lead

Responsibilities:

• As the existing product is implemented in legacy technologies (Java Web Objects), understood the old technology and functionality to Architect on the technologies to use to migrate this tool to newer technologies.
• Done multiple POC and present them to the client on the back end approach we can follow and implement the new tool.

• Client appreciated this approach and this reduces the overhead of multiple teams getting involved in the development of future changes to be done.
• Deliverables are delivered in Agile Methodology
• Developed a Spring Boot application(MVC) to do the core business logic of the existing application without impacting the front end.
• Done POC on Drools rule engine and Keystone Rule Engine framework(internal) to come to decision on which Rule Engine to use.
• Used Keystone Rule Engine Framework after requesting some enhancements to the framework.
• Used the Keystone Rule Engine Framework to perform all the business logic.
• Used Velocity templates to interact with the end carrier API’s and to get the response back such that no need minimize the effort of changing request context every time.
• Used Junit for preparing the test suites.
• Used XML Beans to marshal and un marshal the XML Objects to perform the business logic.
• Used Hibernate as the ORM layer to connect to Oracle Databases.
• Used JSON - Jackson to parse the JSON objects
• Used BootStrap to configure application properties and other properties.
• Developed a SOAP client to interact with the carrier end point SOAP Web Services.
• Used GitHub as the source repository and TeamCity as the continuous integration tool for building and deploying the application.
