What I'm looking for

I'm seeking remote roles (full-time or freelance) where I can design end-to-end measurement, automate QA and reporting with Python/LLMs, and partner with growth teams to turn analytics into action.

I'm a senior GTM and GA4 implementation specialist who builds reliable measurement foundations and turns raw web data into actionable funnel insights for growth teams. I map business goals to dataLayer/GA4/GTM, design Python+LLM tools to automate audits, QA, enrichment, and reporting, and deliver dashboards and activation that help teams measure, trust, learn, and act.

I have 8+ years across e-commerce, healthcare, finance, and SaaS, implementing Enhanced Ecommerce, SPA routing, Measurement Protocol, and offline conversion bridges, and integrating dynamic remarketing and ad platforms. I collaborate remotely with engineering and marketing, author playbooks and developer handoffs, and ship AI-assisted tooling and automation to speed decisions with higher confidence.
