About this Gig
I work with messy, real world data the kind that has missing values, wrong data types, duplicates, inconsistent formatting, and columns that make no sense until you dig in.
What I can help with:
- Cleaning and standardizing raw datasets (CSV, Excel, JSON)
- Handling missing values properly not just dropping them
- Fixing data types, parsing dates, normalizing text fields
- Removing duplicates and outliers with documented reasoning
- Feature engineering and transformation for analysis or ML
- Writing and optimizing SQL queries for data extraction
- Storing clean data in a structured SQL database
- Building reusable, well-commented Python scripts using pandas
I've worked with real datasets and I know that every cleaning job is different. Send me a sample of your data before ordering if you're not sure which package fits I'll tell you honestly what it needs.

FAQ
What file formats do you accept?
CSV, Excel, JSON, or a direct database connection. If it's something else, message me first.
My dataset is large, is that a problem?
Depends on the size. Message me with details and I'll let you know if the timeline needs adjusting.
Will I get the cleaned data back or just the script?
Both the cleaned output file and the Python script that produced it, so you can rerun it anytime.
Do you work with SQL databases too?
Yes. I can write queries, design schemas, and store your cleaned data in a structured database. That's included in the Premium package.
