Brief description of the project: `

Enterprise Decision Platform (EDP) is Discover card acquisition system which facilitated the decisioning process. With the application submission either by call or website, EDP source the info from internal systems and external vendor calls (for example, MSA, Experian, EFX, LexisNexis etc.), aggregate and pass to Blaze decision engine. A Blaze decision engine is a customizable automation platform that executes decisions based off customer credit policies and rules. It is designed to help organizations save time and money by executing credit decisions and allows manual underwriters to focus on more unique situations. Based on application submission, Blaze either approve, decline, or mark application for agent review after couple of iterations.

This project is mainly to develop and migrate source systems, decision aggregator and decision engine from legacy to modern systems in 3 different phases. Phase #1, migrating to modern source systems, #2 migrating prebureau decisioning to cloud base decision engine, #3 migrating aggregator to different cloud-based APIs. All data i.e., req and res payload and Blaze decision are saved to AWS snowflake for analytic purpose.

The threshold was setup either by automated system (based on monthly transactions history) or user defined.

In Fraud Alerts apps, Card Services send FCMS (Fraud Card Management system), CFF(Confirmed Fraud Feed) and Settlement transactions coming from merchant to Fraud Alerts apps and these transactions were stored and alerts were generated and send to DMS system (Data Messaging Services)

In Verify+ apps, we mainly covered 3 things, address standardized of user submitted input parameters, saving user match data (comparing data from mainframe system and user inputs) and calling FraudNet( third party apps) for getting fraud score based on that Merchant, Acquirer or other Fraud service provider decide fraudulent transactions.
