Project Description:

UK Retail & Credit cards data is extracted from RBSG internal/external feeder systems on a daily, weekly and monthly basis and stored in Teradata Staging area tables. The data from these tables are extracted and transformed to create files in the required format for Detica. The files are transferred to the Detica NetReveal Builder server for building networks & scoring them. After the builder process is successfully completed, NetReveal visualizer is kicked off to load the networks to Visualizer.

The objective of this project would be to build on the pilot configuration to deliver a strategic system to support investigation of sleeper accounts, with the following targets:

  • Enable identification of fraudulent accounts not flagged by the current suite of tools in place.
  • Deliver a solution scaled for use by GS&F staff where we have a suspicion that potential financial crime activity is being undertaken against the Group and requires investigation (Group = our customers, our processes, our staff).
  • Deliver match commonality (to be defined but examples include customers, phone numbers, geographic locations etc.) should be easily accessible to the operator to aid determination of potential fraud.
  • Deliver match commonality with external Data sources such as FISS and FIND
  • Deliver operational and other forms of reporting.

Responsibilities:

  • Involved in understanding architecture of Project.
  • Coordinating & Preparation of Mapping Sheet with Business Team for different Interfaces (Source System)
  • Extraction, Transformation and loading of data from source systems into staging. Various transformation rules are applied.
  • Created Informatica mappings and re-usable using different transformations.
  • Involved in complete UNIT testing and test data preparation.
  • Involved in preparing component design document for reference.
