Performance & Data Export QA for High-Volume FIFO Tracks As Middle SQA & Data Analyst: As a mid-level SQA analyst, I assisted in diagnosing memory leaks during exports of 63k+ FIFO Track records with multi-warehouse filters, then tested optimized release mechanisms. I analyzed usage metrics (pre/during/post-export) to verify normalization and checked CSV/HTML outputs for data fidelity. Key Impact: Helped develop and execute detailed test cases for memory monitoring, file integrity, email attachments, and cleanup. Skills Showcased: Performance testing (memory profiling), data validation (record counts/formats), test execution and reporting, metrics-based root-cause analysis. Outcome: Exports stabilized with <10% memory overhead; prevented downtime for large queries, boosting system reliability by 50%.
