I will clean and transform messy data using python and sql

I specialize in turning messy, unorganized data into clean, usable datasets.

WHAT I DO:

Remove duplicates, handle missing values, and fix formatting errors

Data validation and deduplication (remove 100% duplicate rows)

Handle outliers and data type mismatches

Clean datasets from Excel, CSV, or databases

Generate data quality reports

MY APPROACH:

1. Audit your dataset (identify errors, duplicates, inconsistencies)

2. Clean using Python (Pandas, NumPy) or SQL

3. Deliver cleaned data + detailed cleaning report

4. Provide automated cleaning script for future use

IDEAL FOR:

- Large datasets with quality issues (thousands to millions of rows)

- Multi-source data consolidation

- Preparing data for analysis or reporting

- One-time cleanup or ongoing maintenance

MY EXPERIENCE:
