Alexandra D.

Data Analytics, Data Extraction and Data Science expert with over 15 years of experience I began freelancing in 2019 and have since completed successful engagements with over 25 different clients from a diverse range of industries, earning a top 1% ranking on Upwork. My expertise spans across the modern data stack from data engineering and extraction to analytics, visualization and prediction. Prior to freelancing, I spent almost a decade at various Ad Tech startups in NYC, working my way up from data analyst to building and managing high-performing Business Intelligence teams. In this fast-paced startup environment, I seized opportunities to learn multiple programming languages to build reporting and analytics platforms from scratch as well as lead implementation efforts for BI tools such as Tableau and Sisense. My passion for data and data-driven approaches to business began during my days as a PhD student at Columbia Business School, where I studied advanced statistics and researched the psychology underlying consumer behavior.
