• Designed and executed test cases covering credit evaluation workflows, bureau integration (e.g., CIBIL), and internal scoring models.
• Validated Turnaround Time (TAT) KPIs by measuring the time taken between loan application initiation and credit decisioning.
• Performed CAN file verification to ensure correct mapping between applications and applicant profiles in backend systems.
• Conducted end-to-end testing of APIs related to credit eligibility, risk assessment, and document submission.
• Collaborated with the business team to review rule-based scenarios (e.g., salary bracket, credit score thresholds).
• Logged and tracked defects using JIRA; verified fixes and performed regression testing in multiple sprints.
• Supported UAT execution by coordinating with client-side credit analysts and business users.
