The Challenge

Legacy boundaries,
sluggish growth.

The legacy Shopify theme suffered from critical mobile UX issues, massive checkout funnel drop-offs, and abysmal loading speeds. This created friction that severely bottlenecked overall sales revenue.

Slow Load Times

5.4s average page load on mobile 3G

📱

Poor Mobile UX

Tap targets below 44px, causing severe horizontal scroll issues

🛒

Checkout Friction

A tedious 6-step checkout funnel with no guest checkout capability

📊

No Funnel Analytics

Zero visibility into conversion drops and user checkout abandonment
