I will write, fix, and optimize SQL queries

I'm new to Fiverr, but not new to working with databases and SQL.

With an IT engineering background and extensive experience working with databases, I can help you write new SQL queries, fix queries that are not working correctly, and optimize existing queries for better performance.

What I can help you with:

  • Write SQL queries from your requirements
  • Fix SQL syntax and logic errors
  • Debug queries returning incorrect results
  • Optimize slow or inefficient queries
  • Improve JOINs, subqueries, CTEs, and complex queries
  • Review and simplify existing SQL
  • Suggest indexing and performance improvements when relevant
  • Analyze queries and execution plans when provided

Supported databases:

  • MySQL
  • PostgreSQL
  • Microsoft SQL Server
  • Oracle Database
