About this Gig

I'm a SQL developer and production support engineer with 4.5+ years of hands-on experience with SQL Server and Oracle in live production environments.

I can help you with:

  • Writing complex SQL queries (joins, subqueries, CTEs, window functions)
  • Optimizing slow-running queries for better performance
  • Debugging stored procedures, views, and functions
  • Fixing query errors or unexpected results
  • Data extraction and report-ready query design

Send me your requirement or existing query, and I'll deliver a clean, tested, well-commented solution.

Let's discuss your requirement before you place an order, so I can give you an accurate timeline.
