- Analyze existing ETL validation processes and identify automation opportunities .

- Develop AI-driven validation frameworks for data pipelines.

- Implement anomaly detection for continuous data quality monitoring .

- Compare source data against ETL outputs to identify and track discrepancies.

- Automate record count, completeness, and consistency checks across pipelines.

- Generate AI-assisted validation reports that explain detected issues in clear, actionable terms.

- Integrate AI validation capabilities into AWS data platforms and workflows (Glue, Lambda, Redshift, Athena, S3).

- Evaluate how AI can be used to deliver in-depth QA analysis of deliverables .

- Collaborate with data engineering, QA, and business teams to define data quality rules, thresholds, and SLAs .
