Struggling with a slow, broken or confusing SQL query?


I'll fix, write and optimize it for you.


With 25+ years of experience in data and analytics, I work with SQL Server, Azure SQL, MySQL and BigQuery.


What I can do:

  • Fix errors and debug queries
  • Write new queries, joins and stored procedures
  • Speed up slow queries and review your schema
  • Explain the solution so you can reuse it


What I need from you:

  • Your query or a description of what you need
  • The database type and a sample of the table structure (no confidential data)


Why work with me:

  • Clear, reliable, well-documented work
  • Fast replies and on-time delivery
  • Any timezone


Message me before ordering if you're unsure which package fits. I'm happy to help.
