Need help with an SQL query or database task?


I can help you write, troubleshoot and improve SQL queries for your database.


I can work with:


  • SELECT queries
  • JOINs
  • WHERE and HAVING
  • GROUP BY and aggregations
  • Subqueries
  • Filtering and sorting
  • Data extraction
  • SQL query debugging
  • Basic data analysis

I have experience working with SQL and databases and can work with Oracle SQL and other SQL environments depending on the project requirements.


Please send me your database structure, sample data and requirements before ordering when possible.


If you have an SQL error, send me the query and error message and I will help identify the problem.
