I'm Not an Agency. I'm the Engineer Who Builds It.

One senior engineer. Ten years of depth. No handoffs.

Tired of junior staff learning on your dime?

TagSpecialist is a Vancouver-based practice of one. I'm a senior data engineer with 10 years building tracking and data infrastructure for enterprise advertising campaigns — started after years of watching generalist agencies fumble complex implementations.

No account managers. No middlemen. No juniors.
You talk to me, I scope it, I build it — and I actually know how to make GTM, BigQuery, and server-side tracking work together. Full background, résumé, and references are shared on our first call.

"When you hire me, you get me."
