About David
Structured models reduce human error by 90 percent. We begin by dismantling inefficient spreadsheet designs to build clean, automated dashboards. I integrate INDEX and MATCH, Power Query, and what-if analysis to sharpen your technical edge. VBA basics and conditional formatting serve as the final layer of your analytical toolkit.
I provide a weekly challenge task with feedback to track your progress. Finance beginners will learn to construct pivot charts that actually communicate business value.
My fintech background ensures every technique is grounded in industry standards. These systems exist to save you time and provide clarity. We refine your approach until the output is flawless. Your future efficiency depends on the systems you build today.

Completing a Master of Science in Data Science at Columbia provided a rigorous technical foundation. Most people assume spreadsheets are simple tools for basic data entry.
Having spent 7 years in analytics roles, I see them as the backbone of modern business logic. My 4 years of experience and work with 84 students confirm this reality.
I translate complex data flows into practical, actionable insights for working professionals and small business owners. Career switchers and office staff often struggle with the transition to advanced logic. How would your current workflow change if you mastered the end-to-end data stack?
