About this Gig

 Your business data is a mess? Duplicated customers, inconsistent dates, spreadsheets that take forever to open? You don't need to learn SQL I will turn your Excel/CSV files into a clean, fast, organized database.

WHAT YOU GET

  • Duplicates removed, dates and formats standardized, data validated
  • A database structure that fits YOUR business (clients, orders, inventory, reports)
  • Import scripts + documentation source code always included
  • A data quality report: what was wrong and what I fixed
  • Plain-language instructions so you can keep using your data

HOW WE WORK

  • You send your files; I ask the right questions in plain English
  • Regular updates nothing happens without you knowing
  • I speak business, not just databases

MY STACK: SQL Server | PostgreSQL | MySQL | Excel / CSV / Google Sheets

WHY ME: I build real business systems (invoicing, inventory, management platforms) I know how business data should look, not just how to copy rows.

Need more than clean data? I also build the apps and dashboards that feed on your database.

Message me BEFORE ordering so I can review your files and give you an accurate quote.
