At Cikume SA de CV, I optimized complex SQL queries and restructured underlying tables, cutting average runtime by 30%. I also designed ETL pipelines in Azure Data Factory and Pentaho with completeness and consistency checks.
I led an AWS-to-Azure migration, writing SQL validation to reconcile row counts, key integrity, and transformation accuracy before cutover. I developed and validated SSRS reports and Power BI dashboards, checking DAX measures against independently written SQL so reported figures reconciled to source.
