About this Gig

Need a clean, consistent dataset for analysis or reporting? I am a Big Data and AI Engineer with engineering experience since 2018. I help organize Excel and CSV files and check their quality.


Within the agreed package scope, I can:

- Remove duplicate records using rules you approve.

- Standardize dates, text, categories and number formats.

- Identify missing values and inconsistent entries.

- Reorganize columns and combine compatible files.

- Deliver cleaned files and a short summary of changes.


Packages cover 100, 200 or 300 total rows across the included files. File, column and cleaning-rule limits are listed in each package. For larger datasets, complex joins or reusable Python scripts, message me for a custom offer before ordering.


I use Excel, Python and SQL as appropriate. Share a sample, your cleaning rules and expected output so we can agree on scope.


Uncertain values are flagged for review. The original data is kept separately. Revisions cover the agreed rules and supplied dataset.
