My Story

Writer: Erica Mangino GiulianiErica Mangino Giuliani

I never set out to become a data scientist. My career started in hospitality and event management, where I thrived on crafting memorable customer experiences at places like Kings Island and Miami Valley Gaming. While managing operations at Miami Valley Gaming, I became fascinated with the data behind business decisions—from understanding customer behavior to optimizing promotions and streamlining operations. I saw firsthand how data could drive smarter, more strategic outcomes, and that realization led me to pursue a Master’s in Business Analytics at the University of Miami.

Armed with my degree and a passion for data-driven decision-making, I transitioned into data science full-time with the Cleveland Browns, where I built predictive pricing models, optimized fan engagement strategies, and implemented A/B testing frameworks to drive revenue growth. My work focused on bridging the gap between business strategy and advanced analytics, helping leadership make informed, data-backed decisions that directly impacted the bottom line.

At JOANN, I took on an even broader leadership role, overseeing Enterprise Data Science & Analytics, including data engineering, business intelligence, and experimentation. I spearheaded the development of predictive models, machine learning solutions, and causal inference strategies that enhanced customer experiences, optimized supply chains, and delivered millions in revenue impact. One of my proudest initiatives was launching an in-house A/B testing platform, eliminating reliance on third-party vendors and saving the company $1M annually while improving statistical accuracy.

Throughout my career, I’ve realized that data is only as valuable as the decisions it enables. That’s why I’m now pursuing a Doctorate in Business Administration at the University of South Florida, researching analytics maturity in retail—because I believe that businesses don’t just need more data; they need the right strategies to fully adopt and scale advanced analytics.

Today, I sit at the intersection of data science, leadership, and business strategy, helping organizations monetize data, drive innovation, and build high-performing teams. My mission is to transform complex data into actionable insights that fuel growth and innovation.

 

From hospitality to data science, from casinos to corporate strategy, my career has been a journey of curiosity, evolution, and impact, and I’m just getting started.
