I will do data cleaning, preprocessing and data wrangling in python

Messy, duplicated, half-empty data? I'll turn it into clean, reliable, analysis-ready tables.

I'm Muhammad, an MSc-qualified data scientist and data engineer. I clean and structure data so every later step, dashboards, models, reports, rests on something you can trust.

What I do:

• Data cleaning: duplicates, wrong types, missing values, inconsistent text
• Wrangling and reshaping (Python/pandas, SQL)
• ETL pipelines: extract, transform, load from multiple sources
• Merging and joining messy datasets safely
• Feature and column engineering
• Data validation and quality checks
• Medallion pipelines (bronze-silver-gold) and star-schema warehouses
• PySpark for large datasets

Formats: Excel, CSV, JSON, SQL databases and more.

Why me:

• Reproducible, documented pipelines, not one-off hacks
• Every transformation is traceable and re-runnable
• Careful validation so nothing breaks silently
• Fast, friendly communication

Recent work includes a medallion pipeline that hit 5.3x compression with byte-identical, fully reproducible builds across 11 modeling-ready tables.

Please message me before ordering with a sample of your data so I can confirm scope and the right package.
