About
A Global Basketball Journey Shaped How I Solve Problems
From NYC with Belizean roots, I've lived and competed across four continents. Playing professional basketball taught me discipline, composure, and how to perform under pressure—lessons I apply every day as a data professional.
At Visa Consulting & Analytics, I help merchants optimize payment systems through data-driven insights. During this work, I realized my passion: building models and uncovering patterns that drive real business decisions which fueled my passion for Data Science.
I build machine learning models and data pipelines that solve real business problems.
