Frontend development, performance optimization, and large-scale web applications on one of the world's highest-traffic sports platforms, serving millions of daily users.
At Globant, I collaborate with Disney to enhance and maintain ESPN.com, focusing on scalability, clean architecture, and high-quality user experiences. ESPN.COM is one of the most visited sports websites globally, operating at a scale that demands rock-solid reliability, sub-second performance, and strict accessibility compliance.
