I will write sql queries for your data
SQL and ERP Troubleshooting
About this Gig
Struggling with messy data, broken queries, or reports that don't add up? I write clean, accurate SQL to pull, filter, and organize your data so it actually makes sense.
Whether you need a single query fixed, multiple tables joined, or a full data cleanup and audit, I focus on fast, reliable results no unnecessary complexity, just working solutions.
What I offer:
Custom SQL queries (SELECT, filters, joins)
Query debugging and optimization
Data cleaning and reconciliation
Multi-table joins and reporting
Clear written summaries of findings
I work with data from a variety of systems, including legacy and less common platforms that other freelancers often avoid. If your data lives in an older or non-standard setup, that's not a problem I know how to work with it.
My approach is straightforward: understand what you actually need, deliver clean and functional SQL, and communicate clearly throughout. No jargon, no runaround just results you can use.
Send me a sample of your data or a description of the problem, and I'll let you know honestly whether I can help and how fast I can get it done.
Let's get your data working for you.
