GA4 Analytics & CRO Specialist | Ecommerce & DTC Brands

New Delhi, India
$40 per hour
43 jobs
$200K+ total earnings

Most ecommerce brands don't know why their conversion rates are what they are. They have GA4 running, but the data isn't clean. Their dashboards don't tell a story. They run A/B tests without understanding the full customer journey. They're making decisions on incomplete information. I work with ecommerce brands and DTC teams to understand what's really happening and then fix it. I design GA4 implementations that actually work, build dashboards you can trust, run CRO experiments that inform strategy, and help you optimize across the entire funnel. After 14+ years helping Shopify and other ecommerce businesses scale, I know where the drops happen and how to fix them. What I own for my clients: Analytics & Measurement Foundations I design and maintain GA4 and GTM implementations that your team actually trusts. This includes custom event tracking, clean data architecture, custom dimensions, and ongoing audits to keep your analytics from degrading over time. Ecommerce & DTC Analytics (my specialty) I specialize in understanding user behavior across the full ecommerce journey from awareness to repeat purchase. I focus on where people drop off, why they convert, product performance, and multi-channel attribution. The goal is to see the real picture of your business. Experimentation & CRO I help teams run focused, disciplined A/B tests that actually inform decisions. Using tools like Google Optimize and Convert, we test systematically and learn what moves the needle. The goal is better decisions, not just higher conversion rates. Reporting & Strategy I build dashboards and reports that leadership can rely on clean, actionable, and built for decision-making. Not vanity metrics. Real insights that inform how you spend money and where you invest next. How I work: Long-term analytics & optimization ownership — I'm not a setup person who disappears. We work together continuously on what matters. GA4 audits and rebuilds — If your tracking is broken or incomplete, I find it, fix it, and rebuild it right. Conversion analysis and experimentation strategy — I help identify what's actually costing you conversions and test the fixes. Direct collaboration with your team — I work alongside your internal teams, agencies, and developers as a trusted advisor. I'm often treated as an extension of the internal team rather than an external vendor. If you're looking for someone to take ownership of your analytics and CRO strategy not just implement tools and partner with your team over the long term, we'll likely be a strong fit.
