I will deliver actionable sql queries and reports
Acerca de este Servicio
Got data in a database but no one to query it?
I write clean, efficient SQL that extracts exactly what you need no guesswork, no bloated reports.
Before data, I ran a manufacturing startup for 3.5 years.
I know the questions business owners actually ask and I know how to find the answers in your data.
What I deliver:
- Custom SQL queries (PostgreSQL or SQL Server or MySQL or others)
- CTEs and window functions for complex analysis
- Sales trends, customer segmentation, cohort analysis
- Clean results exported to Excel or CSV
- Documented queries you can reuse
Typical questions I answer:
- Which products are underperforming this quarter?
- Which customers haven't ordered in 90 days?
- What is my average order value by region?
- Where is revenue leaking?
Message me before ordering share your table structure and the questions you need answered. I will confirm I can deliver before you pay.

FAQ
What do you need from me to get started?
Your table structure (column names and data types) and the specific questions you want answered. A sample of your data helps but is not required.
Will I be able to understand and reuse the queries?
Yes. Every query is commented and explained so you or your team can run and modify it without needing me again.
Which databases do you work with?
PostgreSQL and SQL Server primarily. I can also work with MySQL, SQLite and others. Message me first if you're unsure.
