I'm Saif, a Data Analyst leveraging Python, SQL, and Power BI to turn messy raw data into actionable decisions not just pretty charts.
One example:...
About this Gig
Stop wasting hours manually fixing messy spreadsheets.
As a Data Analyst, I know that bad data leads to bad decisions. If your data is full of duplicates, missing values, or wrong formats, your Power BI dashboards and Machine Learning models will fail.
I am here to handle the dirty work for you. Using Python and Pandas, I will transform your raw, unstructured data into a clean, analysis-ready dataset.
️ My Python Data Cleaning Services Include:
- Removing duplicates & handling missing values (NaN)
- Merging/Joining multiple CSV, Excel, or JSON files into one
- Fixing incorrect data types and formatting messy dates
- Detecting and treating outliers
- Advanced Data Wrangling and string manipulation
- Feature Engineering (creating new calculated columns)
What You Get:
- Clean, structured dataset (CSV/Excel format)
- The Python script I used (so you can use it again in the future!)
- A brief summary report of the changes made
Don't let dirty data ruin your project. Send me a message right now, and let's get your data cleaned today!

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.
