About Us
Meet the Maker
I’m Whittfield Holmes, a website strategy consultant, developer, and creator of the Advanced DataLayer Tracker (ADT)—a powerful solution built to help marketers, analysts, and developers tame messy tracking setups and unlock cleaner, more actionable data.
Over the past decade I’ve worked with global brands and fast-moving teams to streamline their analytics, optimize user experiences, and ensure data isn’t just collected—but trusted and used to drive growth. With ADT, I’ve taken those lessons and packaged them into a tool that makes enterprise-grade tracking accessible to anyone who’s serious about measurement.

My Mission
With over a decade of experience in web analytics, implementation strategy, and full-stack WordPress development, I’ve worked with global brands to design and deploy scalable tagging architectures, seamless consent integrations, and robust analytics ecosystems. My goal has always been the same: to turn complex data challenges into elegant, dependable solutions.

Why I Built ADT
Marketers have been wrestling for years with duplicate events, unreliable ecommerce tracking, and consent chaos. I created Advanced DataLayer Tracker to solve those problems in a way that’s scalable, consent-aware, and easy to implement—without the need for endless custom code or maintenance nightmares.
Today, ADT powers clean, deduped data layers for businesses that demand accuracy and actionable insights. From startups to enterprise brands, users are able to see the full customer journey, export ready-to-import GTM containers, and build analytics they can trust.
