Tired of messy, inconsistent, or incomplete data slowing you down?

I'll clean, transform, and analyze your dataset using Python and Pandas so you get reliable, ready-to-use data fast.

What I handle:

  • Missing values, duplicates, and null treatment
  • Column standardization, data type fixes, formatting issues
  • Outlier detection and removal
  • Merging, reshaping, and filtering datasets
  • Exploratory Data Analysis (EDA) with clear visualizations
  • Summary statistics and key insights

Deliverables (depending on package):

  • Cleaned CSV/Excel file
  • Python script (.py or .ipynb) fully commented
  • Charts (bar, histogram, heatmap, scatter)
  • Written insights / report

Tools: Python, Pandas, NumPy, Matplotlib, Seaborn

Formats I accept: CSV, Excel (.xlsx), JSON, Google Sheets export
