- Develop reusable SQL validation procedures and automated reconciliation utilities.
- Investigate complex data discrepancies across large enterprise datasets.
- Optimize reconciliation queries and validation processes for performance and scalability.

3. ETL / ELT Testing and Validation

- Lead testing of ETL/ELT pipelines developed using SQL Server, Azure Data Factory, and Microsoft Fabric.
- Design comprehensive testing strategies covering data ingestion, transformation, integration, and downstream consumption.
- Validate full loads, incremental loads, CDC processes, upserts, and historical data processing.
- Develop test scenarios for data mapping, schema changes, null handling, duplicate detection, and exception processing.
- Lead regression testing following pipeline changes and production releases.
- Ensure appropriate validation coverage across staging, curated, and reporting layers.
- Collaborate with data engineering teams to identify and resolve transformation defects.

4. Microsoft Fabric Migration Quality Assurance

- Lead data quality and reconciliation activities during migration from SQL Server and Azure Data Factory to Microsoft Fabric.
- Define source-to-target validation strategies for Fabric Lakehouse, Warehouse, and data pipelines.

- Identify and investigate migration-related data discrepancies.
- Develop automated validation processes for large-scale data migration.
- Provide quality assessment and supporting evidence for migration readiness and production cutover.
- Support post-migration stabilization and production data quality monitoring.

5. Data Quality Automation and Framework Development

- Design and implement reusable, scalable data quality automation frameworks.
- Develop automated validation scripts using advanced SQL, Python, and other relevant technologies.
- Establish metadata-driven or configuration-driven reconciliation approaches where appropriate.
- Automate checks for completeness, uniqueness, referential integrity, data validity, and business rule compliance.
- Integrate data quality checks into ETL/ELT workflows and deployment pipelines.
- Implement automated exception reporting, quality dashboards, and defect identification.
- Reduce manual testing effort through standardized and repeatable validation processes.
- Evaluate and implement suitable data quality tools and frameworks.

6. Production Data Quality and Root Cause Analysis

- Lead investigation of complex production data quality incidents.
- Analyze discrepancies across source systems, transformation layers, and Power BI reporting outputs.
- Perform root cause analysis and recommend corrective and preventive actions.
- Identify recurring data quality issues and implement automated controls to prevent recurrence.
- Establish monitoring mechanisms and measurable data quality indicators.
- Coordinate with engineering and business teams to prioritize and resolve critical data defects.
- Ensure production data quality issues are appropriately documented, tracked, and resolved.

7. Data Quality Governance and Standards

- Establish standardized data validation and reconciliation methodologies.
- Define data quality metrics, thresholds, exception handling procedures, and reporting mechanisms.
- Maintain traceability between business rules, transformation logic, and validation test cases.
- Support data lineage, metadata management, and auditability requirements.
- Contribute to data quality documentation, test evidence, and release sign-off processes.
- Collaborate with data architects to ensure data quality controls are embedded within platform design.
- Promote a proactive, engineering-led approach to data quality.

8. Team Leadership and Cross-Functional Collaboration

- Provide technical leadership and mentoring to data quality engineers.
