About this Gig

Are you struggling with messy, unorganized data, or need to extract specific insights from your database? I am here to help!

Raw data is rarely ready for business use. I specialize in transforming raw database tables into clean, structured, and actionable datasets using MySQL. Whether you need complex queries, data normalization, or accurate data extraction to Excel/CSV, I've got you covered.

What I offer in this gig:

  • Data Extraction & Querying: Writing optimized SQL queries (JOINs, Aggregations, Subqueries) to pull exactly the information you need.
  • Data Cleaning & Manipulation: Handling missing values, removing duplicates, fixing inconsistencies, and standardizing data formats.
  • Database Normalization: Restructuring your tables to eliminate redundancy and improve data integrity.
  • Entity-Relationship Diagrams (ERD): Mapping out table relationships for a logical and solid database structure.
  • Exporting Data: Delivering your fully prepared data in your preferred format (CSV, Excel, etc.).

Why choose my service? I don't just write SQL code; I understand the business logic behind the data. Because I also build advanced interactive dashboards, I know exactly how data needs to be structured
