Project: Authorizations

Role : Software Programmer

The objective of the project is to provide development, enhancement and maintenance services to the high-speed real-time Credit Card Authorization Application System which is built using Java, Mainframe and ab initio, Python and R.

The application should authorize a transaction, either decline or approve, that has originated from a point of sale when a customer swipes his credit card and should monitor for fraudulent activities. This system also implements and supports external software provided by agencies like FICO in order to comply with regulations enforced by Federal government and other agencies. A new machine learning application is built to derive scores to help in fraud clarification.

The system also interacts with other internal applications for post transaction decisions, post processing engine which processes monetary and non-monetary transaction and communicate with different external systems like HP Non-Stop Tandem, MPP, DPP, FICO etc. Several JAVA, Ab initio, CICS Online and Batch applications, Python and R machine learning applications are in scope for this project.
