   Working as a Software Development Engineer for Amazon Business Payment Product team. • Developed Small Business Cobranded Credit Card (SBCC) application submission workflow, which has served millions of customers using Java Spring Framework. The workflow contains Amazon.com card details page to show application instructions and card benefits, application submission APIs to gather application details and send applications to American Express, card maintenance APIs to fetch and store credit card details from Amex and post-submission APIs to add card to customer’s wallet and issue customer card signup bonuses. • Used Java Spring Framework to build back-end APIs with injected front-end assets developed by React to show prime card bonus products on Amazon.com for millions of SBCC card holders who can earn cash back when checking out with SBCC cards. • Designed a benefit reconciliation system with 100+ QPS using Native AWS components like Lambda, StepFunctions, EventBridge Simple Queue Service, and S3 to validate 100K+ transaction benefits that Amex grants to customers daily, reconcile mismatch benefits with Amex by generating a mismatch report weekly and sending it to Amex, and close the mismatch reconciliation workflows only when Amex reports the correct benefits have been granted to customers. Building Unified Financing Offer experience using Spring Framework and JSP on Amazon.com product details page to show SBCC card benefits (cashback, monthly payments, or paying bills later) for the given products to 10 million+ customers with cobrand cards and to give customers a chance to pre-select card benefits (instead of selecting on checkout page) to aid in better purchase decisions.
