GA4 Specialist - Funnel Tracking for Custom Ecommerce (Not Shopify)

We need someone to set up GA4 funnel tracking for a direct-response ecommerce business. The site is mostly custom PHP though there is a small Shopify instance that receives 5% of our traffic. Our funnels are custom PHP, and checkout happens through Sticky.io.

What we're tracking

• Funnel step progression and drop-off
• Conversion rates across ~20 funnels
• Purchase events from Sticky.io

What we're NOT doing

• Full analytics ecosystem
• Attribution modeling
• GTM (had serious issues with this in the past and it has never worked, honestly)

I have a detailed brief ready for serious candidates. You'd work with our backend dev who can implement. I need someone to audit, architect, build out, and QA.

Timeline: ~30 days
