Messy data? I will clean it like a machine, with a human touch.


I am a data engineer with 2.5+ years at Walmart Global Tech, where I operated 160+ real-time data pipelines. I turn raw, messy datasets into clean, analysis-ready data: missing values, duplicates, wrong data types, inconsistent formats, outliers, and broken columns.


What you get:

  • Cleaned dataset (CSV or Excel)
  • Missing-value handling and data type fixes
  • Duplicate removal and format standardization
  • Outlier detection and treatment
  • Feature scaling / transformation on request
  • Reusable, documented Python cleaning script (Premium)
  • A summary report of every change made to your data

Why me:

  • Production-grade standards: your data is validated, not just tidied
  • Every transformation documented, nothing silently changed
  • Clear communication and on-time delivery

Not sure which package fits? Message me with a sample of your data and I will confirm scope and price before you order.
