Python Data Cleaning and Preprocessing Specialist Pandas ML Ready Datasets
India
Inglese, Hindi
Chi sono
I help businesses and data scientists turn messy, unusable datasets
into clean, ML-ready data — fast and professionally.
What I handle:
✅ Missing values (smart imputation — not just mean/median)
✅ Dirty placeholders: UNKNOWN, ERROR, N/A strings
✅ Wrong data types — numeric, datetime, categorical conversion
✅ Outlier detection and treatment
✅ Feature Engineering
✅ Scaling & Normalization
My approach: I analyse WHY data is missing and choose the correct
strategy — probabilistic sampling, business logic or feature engineering.
Tools: Python · Pandas · NumPy · Sklearn · Matplotlib · Seaborn
