About this Gig
Garbage in, garbage out.
If your raw data is messy, your dashboards and ML models will fail.
Most freelancers just run basic dropna() commands. I use advanced Python & Pandas to fix structural corruption and turn chaotic files into analysis-ready datasets.
The Proof:
I recently cleaned 53,000+ rows of corrupted scraped data. Embedded line breaks were splitting rows, and extreme outliers ruined the math. Instead of deleting broken rows, I built a Pandas pipeline to fix the source, engineer new features, and cap outliers. I bring that same logic to your project.
What You Get:
- Data Preprocessing (Handle missing values & duplicates)
- Data Integration (Merge CSV, Excel, or JSON)
- Advanced Wrangling (Fix dates & string manipulation)
- Outlier Detection & Feature Engineering
- Clean dataset delivered in CSV/Excel
- The reusable Python script to automate forever
Perfect for: Data scientists needing data cleaning for machine learning, or anyone with corrupted web scraping data.

FAQ
Q: Is my data safe and secure?
Absolutely. I take data privacy extremely seriously. I am happy to sign an NDA before we start. Furthermore, all your files are permanently deleted from my computer and cloud storage immediately after delivery.
Q: What file formats do you accept?
CSV, Excel (.xlsx/.xls), and most structured text-based formats. Message me if you have a different format.
Q: What tools do you use to clean the data?
I primarily use Python (Pandas, NumPy) because it is the most powerful and fastest way to handle large datasets. However, if your dataset is very small, I can also use Excel Power Query.
Q: Can you clean data that is inside a database (SQL)?
Yes! I have experience with SQL. I can write complex queries to extract the clean data you need directly from your database before exporting it to a file.
Q: Can you handle very large datasets?
Yes, check my package tiers for row limits, or contact me before ordering for a custom quote on larger datasets.
Q: Will I get the Python script used to clean my data?
On request, yes I can include the cleaning script alongside your cleaned file so you can reuse it on future data.
Q: Can you also build a dashboard once the data is clean?
Yes! I am also a Power BI specialist. Once we clean your data, I can easily build an interactive dashboard for you. Message me so we can discuss a custom package for both.
