I help businesses troubleshoot, repair, and optimize SQL queries and stored procedures.

With more than 20 years of SQL and database experience, I can help with slow queries, errors, unexpected results, inefficient joins, complex stored procedures, and reporting queries that are difficult to maintain.

Typical work includes:

• Query troubleshooting and performance optimization • Stored procedure review and repair • Query logic and join improvements • Index and execution-plan recommendations • SQL Server and BigQuery support • Clear explanations and practical documentation

To get started, please provide a sanitized query or stored procedure, relevant table definitions, your expected result, and any error messages or execution-plan information you can share.

I do not need production credentials or direct database access. Please do not send passwords, confidential data, or sensitive customer information.
