You will get Fix SQL Issue / Debug Query
Project details
If your SQL query is taking too long to run, throwing errors, or not giving the right output — I can fix it quickly and cleanly.
I’ve spent more than a decade working with large datasets, performance-heavy pipelines, and production SQL environments across SQL Server, MySQL, Oracle, and PostgreSQL. My focus is always on building queries that are fast, stable, and easy to maintain.
