I will write sql queries to extract and analyze and your data
About this Gig
Need data pulled from your database but don't know SQL?, Or have complex queries that are running too slowly?.I will write clean, efficient, well documented SQL queries that get you exactly the data you need.
What I can help with:
- Write queries to extract specific data from your database
- Build reports and summaries using aggregations and joins
- Create CTEs for complex multi step logic that is easy to read and maintain
- Optimize slow running queries for better performance
- Write validation queries to check data accuracy and completeness
- Build reusable query templates your team can use repeatedly
I have written SQL queries professionally for daily operational reporting, built validation logic across datasets with 100,000+ records, and reduced reporting turnaround time by 30% through reusable SQL workflows.
What I need from you:
- A description of your database structure (table names and columns) and what data or report you need.
- Screenshots or a data dictionary are helpful but not required.
Let's get your data working for you!

FAQ
What database systems do you work with?
MySQL, PostgreSQL, SQL Server, Snowflake, SQLite, and BigQuery.
Do I need to give you access to my database?
No. Just share your table structure, column names, and sample data. I will write and test the queries without needing direct access.
Will I be able to understand and modify the queries myself?
Yes. I include clear comments explaining what each part of the query does so you can maintain and modify it going forward.
What if I don't know my table structure?
Message me before ordering and I will help you figure out what information I need to get started.
