Are you struggling with unorganized, or duplicate data in your SQL database?

Raw, dirty data can completely ruin your business reports, dashboards, and data analytics results.

I am here to help! As a data analyst, I will use expert SQL queries to clean, format, and prepare your datasets so they are completely accurate and ready for analysis. Whether your data is in MySQL, PostgreSQL, or an Excel/CSV file, I will structure it perfectly.


What I Will Do For You:

  • Data Correction: Fix logical errors, structural mistakes, broken text, and fill missing or NULL values based on your exact needs.
  • Data DeDuplication: Identify and completely remove duplicate records to ensure data accuracy.
  • Data Formatting: Standardize columns (dates, phone numbers, text casings), convert data types, and split or merge fields.
  • Data Preparation: Write clean SQL code with joins and filters to get your tables ready for Power BI, Tableau, or Excel dashboards.
