• Create audit-ready QA tables to track failed checks, schema mismatches, and data regressions.
• Track end-to-end lineage and KPI evolution using OpenMetadata (with Glue/S3/Athena).
• Auto-classify columns as PII, derived, or forecast-driving fields using AWS Glue Tags/Scripts.
• Provide CTAS-based Athena queries for building QA dashboards and UAT verifications.
• Build BI-ready, QA-approved datasets for downstream tools like Superset and Power BI.
• Establish reusable profiling and validation dashboards for data quality and business teams.
• Collaborate with engineers, QA, and business SMEs to finalize data validation logic.
