I will optimize sql database performance and fix slow queries

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"

Before ordering: Please message me with your queries or schema so I can confirm scope and recommend the right package.

Let's make your database fast.
