I have worked with Opus Software Solutions as a Development Lead for the client - Western Union.

• I was involved in the enhancement of the product called Real Time Risk Assessment which is part of compliance division.
• Any transaction that is initiated for money transfer through Western Union has to go through compliance checks.
• The compliance checks can be done on the actual sender and receiver to stop transactions originating or going to black-listed peoples.
• The compliance also imposes limits on the max amount of transaction and the number of transactions in a particular corridor and the system has to analyse the transactions in real time.
• The application is built using the Servlet, JMS, MDB, ESB and the drools on Jboss server.
• The database used in the system is DB2.
• The application interacts with IBM EAS.
• The application also invokes web service to interact with some other applications.
• The Rule Management component is built using the Struts framework.
• The DB calls are made using the JDBC as well as hibernate.
• I was also involved in the enhancement of the backoffice component which is built using the Spring Batch framework and the drools engine.
• Initially the system has the capability to process 0.8 to 1 million transactions in 10-12 hours.
• The upgrade was done so that it can process 4 million transactions in a SLA of under 18 hours and there are lot of changes done at logical side related to the overall batch processing.
• The current version did not had drools package but the upgraded one is provided for certain data normalizations.
• In addition to that the Jboss container is made available at the batch side whereas existing one is a standalone batch.
• The connection pool created by the jboss container is made available to the Spring batch and many of the queries used in the batch was analysed on index, the query plan and then integrated in the system to achieve the sla.
• I have worked in all this phases and I am working both on performance tuning as well as the functional side.
• I have used Dependency Injection, Spring JDBC, Spring core in this project and have a good understanding of Spring with Hibernate and Spring MVC concepts.
