• BBPS Bill Payment Integration: Integrated BBPS (Bharat Bill Payment System) bill-fetch and bill-payment flows across multiple billers and service categories, with an automated refund service to reverse failed transactions, achieving a 90% success rate across billers through resilient retry and error-handling logic on top-up and payment confirmation calls. • Reconciliation Automation Service: Built an automation service that compares the company's ledger, service-wise, against external bank statements to surface extra debited/credited transactions and other mismatches across multiple banking partners, flagging discrepancies for review instead of manual Excel-based cross-checking; cut reconciliation effort by nearly 70%. • Internal Fund Transfer Service: Built an internal fund transfer service for the credit team to move company funds across internal accounts, using queue-based processing to prevent duplicate requests; routed individual requests as single transfers and switched to bulk processing once the amount crossed a configurable threshold per provider and transaction type, with a maker-checker approval workflow.
