About this Gig

Messy data delaying your business insights or machine learning pipelines? I will clean, query, and transform your raw datasets using Python and SQL to make them 100% production-ready.


What I Offer:

Python Data Cleaning: Handling missing values, removing duplicates, structural formatting, fixing data types, and handling structural anomalies using Pandas and NumPy.

SQL Database Querying: Writing optimized, clean queries utilizing Joins, Window Functions, Aggregate Operations, and subqueries to extract targeted metrics.

Exploratory Data Analysis (EDA): Uncovering hidden distributions, tracking correlation matrices, and creating clear summary visualizations.

Feature Preprocessing: Outlier handling, category encoding, and data scaling to get your data structured perfectly for analytics.


Deliverables:

You will receive fully commented Python Jupyter Notebooks (.ipynb), clean script files (.py), structured SQL query scripts (.sql), and your polished datasets in CSV/Excel formats.


Please send me a short message detailing your dataset format and your analytical goals before placing your order so we can outline the project perfectly!
