We're Not an Agency. We're Your Data Infrastructure Team.

Small Team. Deep Expertise. Real Business Transformation.

Tired of junior staff learning on your dime?

TagSpecialist is a Vancouver-based boutique practice run by a senior data engineer with 10 years of experience building tracking and data infrastructure for enterprise advertising campaigns — after years of watching generalist agencies fumble complex implementations.

No account managers. No middlemen.
The engineer who scopes your project is the engineer who builds it — and actually knows how to make GTM, BigQuery, and server-side tracking work together. Full background, résumé, and references are shared on our first call.

"When you work with us, you get us."
