Savings Catcher

Working on an online tool that performs automated price matching for Walmart items as compared against its competitors and refunds money on higher priced items via gift card credit. Built backend-processing logic for retrieving data from HBase, validating it, querying store transactions and competitor’s data for matching items, finding adjustment price, pushing data to HDFS and updating HBase.

Universal Customer Identifier

Worked on Master Data Management (MDM) to establish a universal custom identifier, and profile that merges profiles from all Walmart properties into one customer. This serves as the single source of truth for customer data for Walmart global e-commerce.
