Simon Keller

Simon David Keller Delgado is Analytics Director at Colibri Digital Marketing and a Google Analytics 4 and Google Tag Manager certified analyst with a Bachelor's degree in Materials Engineering from Universidad Simón Bolívar. He spent five years at Colibri building the agency's analytics infrastructure from the ground up, joining as an Analytics Specialist in 2021 and advancing to Analytics Director, where he leads tracking architecture, attribution modeling, and data strategy for clients across health and fitness, nonprofit, hospitality, and financial services. His engineering background gives him a first-principles approach to marketing analytics: the same precision that governs materials testing applied to tag management, conversion tracking, and performance reporting.
