I will write, fix and optimize sql queries

Need help writing, fixing, or optimizing an SQL query?

I will write clean, accurate, and efficient SQL for your data analysis, reporting, or database needs.

I can help with:

• SQL query writing and debugging
• Complex JOINs, CTEs, and subqueries
• Aggregations and window functions
• Incorrect results and SQL errors
• Query optimization and performance improvements
• Data extraction and reporting queries
• Query formatting and cleanup

I can work with PostgreSQL, MySQL, SQL Server, Oracle, Snowflake, and other SQL databases.

Send me your requirements, table structure, existing query (if any), and expected output. I'll review the problem and provide a clear, reliable SQL solution.

For complex or large database projects, please message me before ordering.
