Description

Senior Data Quality Consultant helping organizations ensure reliable, consistent, and business-ready data. I design and implement data quality frameworks, automated controls, and monitoring for critical datasets used in reporting and decision - making.

I work across the full data lifecycle, from defining data quality standards to validating ETL pipelines, transformations, and data migrations. My expertise includes advanced SQL for large - scale data validation and Python for data cleansing and anomaly detection.

I support stakeholders in identifying root causes of data issues, prioritizing actions based on business impact, and establishing sustainable data quality practices. My approach is pragmatic, structured, and focused on long - term data reliability.
