PROFESSIONAL EXPERIENCE:

Confidential, Jersey City, NJ

Java J2EE developer

Responsibilities:

• Implemented Restful web-services for new functionalities. Examples being write new service to call downstream fact checker service.
• The new services were part of the new transition plan to phase out old legacy code. The new services were based on java8 and Springboot.
• Main frameworks/tech stacks used were jav8,Springboot, micro services, JPA.
• Also worked on bug fixes for current services on the application. This included looking at the production bug tracker and tracing the code to understand the bug. After the fix,unit test cases were written to test it locally before a code-review.
• POC on single-sign-on type internal security mechanism. Transition plan to migrate to a new type of internal SSO. I was part of the team to conduct a POC for the same in a small module.
• Implemented a JPA layer to connect to underlying oracle/mysql dB for the new services.
• Mavenized legacy client-facing applications, and hence making them Jenkins ready. Old code was ant build based and hence not ready for Jenkins type environment. To do that they had to be mavenized and hence all dependencies had to be installed in a maven repo. Internal jars had to be rebuilt. Finally the project structure had to be undone for making it maven ready. Also I had to test them manually as most of these application did not have any sort of unit-testing framework.
• Wrote unit test cases for legacy applications using junit and mockito.
• Followed agile-scrum methodology.

Responsibilities:

• Use Drools framework to achieve on the-fly configurability for the client in order to automate the workflow system.
• Provide a solution for the client wherein the changes to parameters can easily be implemented by the Confidential, rather than waiting for another development iteration.
• Provide a robust solution, that is scalable to multiple rules and also easy to maintain.
• Part of a team that was responsible to create an environment to maintain the rules layer. Part of this was to use the Wildfly server and deploy KIE services over and above it.
• Write REST services that consume the input and then call the above business layer to return the response of the same
• Ensure that this REST service should also handle errors and exceptions as and when the business layer throws Also ensure that the consumer gets meaningful error messages, that are the result of translation of error codes thrown by the business.
• Implement the product's lifecycle: Design, development, quality, deployment and maintenance.
