I will perform massive sql data cleanup and build power bi dashboards

Turn your messy data into powerful business insights! Messy, duplicated, or inconsistent data leads to wrong decisions. As a Senior Data Infrastructure Leader, I specialize in high-stakes data cleansing and advanced visualization using Power BI.

What I offer:

• Massive Data Cleanup: Expert SQL scripts to handle duplicates, orphan records, and data normalization.
• Power BI Dashboards: Interactive, automated reports with advanced DAX measures.
• Data Integration: Connecting Power BI with Microsoft Graph, SQL Server, Oracle, or APIs.
• Data Transformation: Complex ETL processes using Power Query and SQL.
• Relational Integrity: Safe deletion and cleanup without breaking your database structure.

Why hire me?

• Scalability: Ive handled datasets larger than most freelancers can manage.
• Business Intelligence: I don't just show data; I show results.
• Precision: Expert in complex batch deletions and data migration.
