I specialize in data cleaning and transformation, helping you turn messy, inconsistent datasets into structured, reliable, and ready-to-use information. Whether it’s removing duplicates, fixing missing values, standardizing formats, or reshaping your data for analysis, I make sure your dataset is accurate and consistent.
By working with me, you’ll save time and avoid costly mistakes caused by unreliable data. I deliver clean, high-quality datasets in Excel, CSV, or SQL format, tailored to your specific needs.
I focus on:
Thorough data review and cleaning

(Optional add-on): If you need, I can also provide a simple dashboard (Excel, Google Data Studio, or Power BI) to help you quickly visualize insights from your data.
Let’s make your data work for you, not against you.
