Informazioni su questo servizio

7+ years writing and debugging SQL in banking and ERP production environments. I write clean, efficient queries for reporting, data validation, and troubleshooting and I explain what I did so it's not a black box.

What I deliver:

  • SQL queries (SELECT, JOIN, aggregate, subqueries) tailored to your schema
  • Data validation scripts
  • Query optimization/debugging for existing slow or broken queries
  • Brief documentation of logic used

Works with MS SQL Server (my specialty); can adapt to other SQL dialects on request.
