About William
Clean data flows into actionable dashboards once you master the right functions. A bright spreadsheet screen greets us as we start building your first model. We will walk through SUMIFS and COUNTIFS to manage large datasets accurately.
Text functions and error handling become second nature after a few tries. I bring 11 years of experience to help you bypass common mistakes.
My lessons include a mandatory weekly challenge task with feedback for every student. This approach ensures you apply the logic to your own professional files. I use my Wharton background to teach you the math behind the numbers. Your data will finally make sense for your next presentation.

Coffee stains on desk pads remind me that data analysis is messy work. I finished my Master of Science in Business Analytics at the Wharton School before starting a 13 year career. My desk has seen consulting projects and high speed SaaS environments.
I handle nested IF logic and complex data cleaning daily. Conditional formatting is often my first tool for spotting trends.
I track pivot tables and charts to build a story for stakeholders. Are you trying to organize your career or office workflow? I work with career switchers and students who need practical results.
SQL and Python are part of my toolset for deeper insights. What specific roadblock are you facing in your spreadsheet today?
