Most marketing teams are drowning in dashboards and starving for decisions. I fix the measurement layer, from broken tracking and misattributed pipeline to full-funnel attribution frameworks that finance and leadership actually trust. I'm a senior marketing analytics consultant with 10+ years across B2B SaaS, performance agencies, and enterprise environments. I've built measurement systems for NASDAQ's enterprise marketing team, owned the full analytics stack at Refine Labs for a portfolio of B2B SaaS clients, and designed attribution frameworks that connected dark funnel signals โ€” LinkedIn, Reddit, self-reported survey data โ€” directly to closed revenue in Salesforce. Where I operate: -- Attribution & measurement strategy: Multi-touch frameworks, hybrid attribution models, incrementality testing, and holdout experiment design. Built for CMO confidence, not just reporting compliance. -- GA4 & GA4 360 implementation: full lifecycle tracking, event architecture, conversion framework design, GTM governance. I've led enterprise-level gap analyses and rebuilt tracking from scratch. -- BigQuery & data modeling: Dataform pipelines, SQL data models, cross-platform attribution logic from ad platforms through CRM. Not just dashboards, structured, reusable data. -- RevOps reporting: Salesforce/Pardot pipeline reporting, MQL/SQL definition frameworks, lead scoring by source, territory-based goal modeling. -- Executive communication: I translate complex multi-source analysis into strategic narratives for CMOs and demand gen leaders. I don't just deliver data. I deliver a point of view. What working with me looks like: -- You get a senior operator who has owned measurement strategy end-to-end, not someone who sets up GA4 events and hands you a Looker Studio link. I ask the business question first, then build the measurement system around it. -- I work with a small number of clients at a time and I'm direct. If your tracking is wrong, I'll tell you. If your attribution model is misleading your budget decisions, I'll show you exactly where. If you're looking for someone to maintain dashboards, I'm probably not your person. If you need someone who can own your measurement strategy and make it a competitive advantage, let's talk.
