Are your Oracle queries running slow? Do you need complex PL/SQL logic written from scratch or an existing procedure debugged and enhanced?


I am an Oracle SQL specialist with hands-on experience in query optimization, execution plan analysis, PL/SQL development, and database performance tuning. I work with real production-grade Oracle environments and deliver clean, well-commented, production-ready code.


What I can do for you:

  • Analyze, rewrite slow SQL queries using proper indexing, hints, and join strategies.
  • Interpret execution plans to pinpoint bottlenecks.
  • Write stored procedures, functions, packages, and triggers in PL/SQL
  • Refactor legacy PL/SQL code for readability, performance, and maintainability
  • Debug ORA- errors and exception handling
  • Write complex analytical queries


Why work with me:

  • I focus on long-term performance
  • Every deliverable comes with clear explanations so you understand what changed and why
  • Fast turnaround with regular communication throughout the project
