I will do research data analysis and cleaning in python
About this Gig
Hi, I'm Andrei. I have hands-on experience cleaning and analyzing real-world datasets using Python and pandas.
Messy data costs time and hides the answers you actually need. I take raw data in any format and turn it into something usable: removing duplicates, fixing missing values and formatting inconsistencies, and validating the structure before any analysis begins.
Once the data is clean, I explore it using Python and pandas. That means summary statistics, comparisons across categories, trends over time, and visualizations that make patterns easy to see. Every analysis comes with a written explanation in plain language, so the results are something you can actually use, not just numbers on a page.
This service is well suited to research data, survey results, and general business or personal datasets. My goal is to help you understand what your data shows and support your own analysis or decision-making.
If you're not sure what to ask of your dataset, that's fine. Tell me your goal and I'll figure out the right approach.
Message me with your data and what you'd like to know, and we'll go from there.

FAQ
What file formats can you work with?
CSV and Excel are ideal. I can usually work with other formats too, just send me what you have.
Can you help me figure out what to analyze if I'm not sure?
Yes. Tell me what you're trying to find out or what the data is about, and I'll suggest the right approach.
Will you do my assignment or write my thesis content for me?
No. I help you clean, analyze, and understand your own data so you can use the results in your own work. I don't complete graded coursework.
How long will it take?
Basic cleaning is 3 days, cleaning plus analysis is 4 days, and the full report is 6 days. Larger or messier datasets may need extra time, and I'll always confirm before starting.
Do you do statistical testing or build predictive models?
Not yet. Right now I focus on data cleaning, exploratory analysis, and visualization. I'm expanding into statistical analysis and will update this gig as that grows.
