The Problem
A growing fashion retailer was stuck on an aging Magento store, 4.8-second load times, constant plugin conflicts, and a checkout that failed on mobile. Every redesign attempt broke something else, and their dev agency billed by the hour for patches instead of fixes.
Key challenges the client faced
- 4.8s average page load killing mobile conversions
- Fragile legacy codebase where every update broke something
- Risk of losing years of SEO equity in a migration
Our Approach
We planned a staged Shopify replatform: full content and product audit, URL mapping for every page, and a custom theme built from scratch for speed. We migrated 3,000+ SKUs with zero downtime, implemented 301 redirects for every legacy URL, and rebuilt the checkout flow mobile-first before switching DNS.
