About this Gig


Are you dealing with slow SQL queries, database bottlenecks, or performance issues?


I can help optimize your database performance and improve query execution for applications using PostgreSQL, MySQL, SQL Server, Oracle, and other relational databases.


With experience working on high-volume systems and complex SQL environments, I can assist with:

  • Slow query optimization
  • SQL performance tuning
  • Index analysis and recommendations
  • Query troubleshooting
  • Execution plan analysis
  • Database performance improvements
  • Deadlock and locking issue investigation
  • Stored procedure optimization


I work mainly with backend systems, APIs, and relational databases, focusing on practical solutions, performance, and reliability.


Please contact me before ordering for complex database issues or large-scale environments so we can define the best scope for your project.
