Lead root-cause analyses for interest-related discrepancies and customer complaints by querying system data, reviewing transaction detail, and providing written recommendations for corrective actions and process improvements.
Investigate and resolve complex customer escalations related to underpaid interest, misapplied interest, incorrect effective dates, or post-dated payments, communicating outcomes clearly to internal stakeholders and customers.
Prepare and maintain detailed operational procedures, control matrices and reconciliations for internal teams and auditors; ensure all interest processes are documented, version-controlled and audit-ready.
