I will write fix and optimize your google bigquery sql queries

Are slow, expensive, or incorrect BigQuery queries affecting your analytics?

I am a data engineer with 10 years of professional experience in Google Cloud Platform, BigQuery, SQL, ETL pipelines and data analytics. I can write new BigQuery Standard SQL, debug failing queries, and optimize existing queries for better readability, performance and cost efficiency.

I can help you with:

• Writing complex BigQuery Standard SQL queries
• Fixing syntax, logic and data-quality issues
• Optimizing joins, CTEs, subqueries and window functions
• Reducing unnecessary data scans
• Improving partition and clustering usage
• Creating views and scheduled-query logic
• Explaining the solution with clean documentation

You will receive clean, maintainable SQL and a clear explanation of the work completed. Sensitive production data is not normally required; masked sample data and table schemas are often sufficient.
