About this Gig

I'm a data analyst with hands-on experience cleaning, analyzing, and visualizing datasets across HR, retail, and e-commerce. I use Excel, SQL, Power BI, and Python to help you understand what your data is actually telling you and what to do next.


What I bring:


Advanced Excel (pivot tables, XLOOKUP, conditional formatting)

SQL for querying and cleaning large datasets (30,000+ rows)

Power BI dashboards that turn numbers into clear visuals

Python (pandas) for deeper analysis


Recent results I've delivered:

  • Identified a 74% drop-off point in a client's sales funnel using automated pipeline analysis
  • Found a 16% employee attrition pattern and delivered 5 actionable retention recommendations
  • Audited $2.3M in sales data to pinpoint exactly where discounting was losing money


I'm certified through Google's Data Analytics Professional program and Harvard's CS50P, and I bring the same rigor and attention to detail to every project big or small.

Send me your data, tell me what you need to know, and I'll turn it into something clear and useful.
