Raw data is rarely analysis-ready, duplicate rows, inconsistent formats, missing values, and broken structures get in the way before you can even start.

I clean and structure messy Excel or SQL datasets so they're ready for analysis, reporting, or dashboarding. This covers:

Removing duplicates and fixing inconsistent formatting

Handling missing or null values

Standardizing column types and naming conventions

Restructuring data into a clean, usable format

Documenting what was changed and any data quality issues found

I work with SQL Server, DBeaver, Excel, and Power Query, and every transformation is documented so you know exactly what changed and why.

Background: BBA in Management with hands-on SQL and Power BI project work, I approach data cleaning with the end business use in mind, not just tidy rows.
