I will do data cleaning and preprocessing in python for machine learning

 Message me before ordering so I can review your data and scope it fairly.

Messy data ruins models and wastes hours. I'm Yasir Ahmad Malik, an AI Engineer (MSc in Artificial Intelligence). I turn raw, messy datasets into clean, ML-ready data.

What I offer:

• Data cleaning missing values
• Duplicates,
• Outliers
• Inconsistent formats Feature engineering & selection Encoding (one-hot, label) scaling/normalization Text preprocessing for NLP (tokenization, stopwords, lemmatization) Image preprocessing (resizing, augmentation, filtering)
• Time series prep (lag features, rolling stats, stationarity checks)
• Reusable preprocessing pipelines (Scikit-learn ready)
• Before/after data quality report with visualizations

Tools:

• Python
• Pandas
• NumPy
• Scikit-learn
• OpenCV
• NLTK

What you get:

• Clean dataset delivered in your preferred format (CSV/Excel/etc.)
• Documented, reusable code run it on future data yourself.
• A summary of every transformation applied and why Fast, communicative delivery
• Give your models clean data, and get better results.

Send me a sample of your data, and I'll tell you exactly what it needs.
