When GA4, Google Ads, Meta, Shopify, and your CRM show different conversion numbers, you have a measurement problem before you have a marketing problem. I am a performance marketing engineer with 8+ years of experience. I help businesses and paid media agencies fix broken conversion tracking, attribution, analytics, server-side tracking, and privacy-aware measurement so marketing teams can make decisions from reliable data. I work at the intersection of website engineering and performance marketing measurement. My background in JavaScript, React, Next.js, ecommerce, APIs, and web analytics helps me trace data from the website and dataLayer through GTM, server-side GTM, GA4, Google Ads, Meta, CRM, and revenue reporting.

Audit the measurement architecture and conversion goals. 2. Trace important events from the website and dataLayer through GTM and server-side systems. 3. Compare GA4, ad platforms, Shopify, CRM, and revenue data. 4. Find missing events, duplicates, incorrect parameters, consent issues, attribution gaps, and implementation errors. 5. Fix the tracking architecture and validate the data flow. 6. Document the setup for ongoing maintenance. CRO AND EXPERIMENTATION Reliable measurement comes first. Once conversion data is trustworthy, I can also support: - Funnel and checkout analysis using GA4 and business conversion data - Hotjar and Microsoft Clarity analysis - A/B testing measurement and experiment instrumentation ONGOING TRACKING MONITORING Tracking can degrade silently after website deployments, Shopify changes, app updates, consent changes, or advertising API changes. For ongoing clients, I can monitor key conversion signals, investigate anomalies, validate important events, reconcile platform data against business data, and maintain a prioritized measurement backlog. WHY CLIENTS USE AN ENGINEER Many tracking problems are not solved by adding another standard GTM tag. Modern websites involve JavaScript applications, dynamic dataLayers, ecommerce platforms, consent states, APIs, server-side processing, ad platforms, and CRM systems. If your website, analytics, ad platforms, CRM, and actual business data do not agree, I can help find the gap and fix the measurement foundation.
