The data used to arbitrate between offers includes a client profile and interaction data, an offer prioritization score and statistical models based on prior responses to offers. The actual arbitration of offers is performed by a backend product – INTERACT which itself is a Java websphere based JWS provided as a product by IBM . The RTO engine is the middle service layer between OLB and INTERACT .
Primarily worked on enhancement of RTO JWS engine to incorporate new channels – PWM(Private Wealth Management and Mobile in addition to OLB . Duties included but not limited to the following :
1.Understanding the business requirements and translating them into TDD (Technical Design Documents) and providing the same to the solution architect, project managers for review and approval..
