What I'm looking for

I seek measurement-focused roles where I can implement and improve analytics stacks, collaborate cross-functionally, and translate data into business outcomes.

I am an analytics and measurement leader with experience implementing GA4 and GTM solutions, unifying GA and CRM datasets, and delivering actionable insights for e-commerce and lead generation clients. I have a strong technical foundation in SQL, BigQuery, Looker, and JavaScript, and I consistently align measurement work to business goals to drive measurable impact.

I've worked in both corporate and consulting roles—leading measurement implementations, troubleshooting tracking discrepancies, supervising contractors, and delivering client training and audits. I collaborate effectively with account managers, engineers, and executives to ensure campaigns are accurate and insight-driven.
