Process

How I work

Audit

I review your setup and identify where data is breaking or misleading. No assumptions, no guesswork.

Fix

I implement tracking fixes and validate data accuracy at the source. Every change is documented.

Improve

I build reporting and measurement frameworks aligned with your business goals. Designed to outlast the engagement.

Approach

Why this is different

Most analytics setups are wrong because they rely on assumptions instead of validated data.

I work with real data pipelines — not dashboards built on broken inputs.

I validate attribution issues, trace them to the source, and fix them at the implementation level.

Physics degree. 15 years of enterprise measurement. The experimental method applied to every problem.
