Slow SQL queries killing your app's performance? I can fix that.


What I'll do for you:

  • Analyze and rewrite slow SQL queries for maximum performance
  • Review execution plans to pinpoint exact bottlenecks
  • Recommend and design proper indexes (no over-indexing)
  • Optimize stored procedures, joins, and subqueries
  • Database schema review and normalization (1NF, 2NF, 3NF)
  • Before/after performance report with clear metrics


Platforms I work with: MySQL - PostgreSQL - MS SQL Server - T-SQL - PL/pgSQL - Databricks - Microsoft Fabric and many more.


Why work with me:

  • 5+ years as a Senior Data Engineer optimizing production databases at scale
  • Real-world experience with enterprise systems handling millions of rows
  • Comfortable with everything from legacy SQL to modern stacks like Microsoft Fabric and Databricks
  • Clear documentation so your team understands every change
  • I don't just patch queries I explain the "why"
