You will get slow SQL queries diagnosed and optimized
Project details
If your SQL query is slow, inefficient, or causing database performance issues, I can help diagnose and optimize it.
I am a senior software engineer with over 20 years of experience working with data systems and production databases. I specialize in identifying performance bottlenecks and improving query efficiency.
Common problems I help resolve include:
• slow or inefficient SQL queries
• missing or ineffective indexes
• inefficient joins or filters
• poor execution plans
• queries that scan large tables unnecessarily
My approach focuses on understanding the root cause of the slowdown and applying practical optimizations. This may include query rewriting, indexing improvements, or structural recommendations.
You will receive an optimized query, clear explanation of the changes, and recommendations to help maintain good database performance going forward.

About Stan
Senior Software Engineer | Data Pipelines, ETL, APIs
Kings County, United States - 4:29 pm local time
I’ve worked in data-intensive environments where accuracy and timeliness matter. I’m comfortable owning problems end-to-end: mapping the data flow, finding root causes, fixing them, and adding guardrails/monitoring.
Typical projects: backend/API development, ETL automation, vendor/system integrations, data quality & reconciliation, and production debugging/performance tuning.
Recent project: built and deployed Human Impact Index with Python, FastAPI, Docker, AWS, AI integration
Steps for completing your project
After purchasing the project, send requirements so Stan can start the project.
Delivery time starts when Stan receives requirements from you.
Stan works on your project following the steps below.
Revisions may occur after the delivery date.
Review the query
I review your SQL query, table structure, indexes, and problem description to understand the performance issue.
Analyze bottlenecks
I examine execution plans, joins, filters, and indexing to identify the root cause of the slowdown.
