I will write sql queries and build sql reports for your data
About this Gig
Need SQL queries or a data report from your PostgreSQL database? I can help.
I build clean, readable queries and reports that answer your business questions: from simple filters and joins to complex analytics with CTEs and window functions.
WHAT I CAN DO
- Write SQL queries (SELECT, JOIN, aggregation, filtering)
- Build analytical reports with CTEs and window functions
- Debug queries that return wrong results or errors
- Optimize slow queries
- Explain the logic, so you can reuse and adjust the query yourself
WHAT I NEED FROM YOU
- Table structure (schema) or a sample of your data
- A clear description of the result you want to get
- Database type and version (PostgreSQL preferred, MySQL also possible)
HOW I WORK
- I confirm the task with you before starting
- I comment the code and deliver it as a .sql file
- Revisions are included in every package
I have professional experience working with large analytical datasets in banking and credit risk, so accuracy and clear logic are my priority.
Send me a message before ordering if you are not sure which package fits your task. I usually reply quickly.
