Shopify Plus Speed Recovery & UX Optimization
Confidential Skincare Brand
A high-volume skincare brand with bloated app code configurations, unoptimized above-the-fold layout, and a 4.8s mobile Largest Contentful Paint (LCP) time causing cart abandonment.
Conducted technical theme cleanup, removed residual app codes, implemented WebP lazy loading, deferred non-critical Javascript execution, and optimized the product page purchase flow.
WooCommerce to Shopify Performance Migration
Fashion Ecommerce Brand
A scaling apparel brand with heavy database-bloated WooCommerce pages, a catalog of 1,500+ SKUs, slow mobile loading times, and significant organic SEO traffic at risk.
Planned zero-data-loss customer and catalog migration, built custom Liquid templates, structured indexable collection pages, and set up a robust 301 URL redirect mapping strategy.
White-Label Agency Development Scale-Up
UK Digital Design Studio
A fast-growing UK creative agency winning multiple Figma-to-WordPress and custom commerce pitches but lacking senior backend engineers to execute builds on schedule.
Established an agile, silent white-label partnership retainer. We engineered Figma files into pixel-perfect custom Gutenberg blocks, delivering clean, Edge-rendered codes under NDA.
Programmatic Faceted Navigation Optimization
Confidential B2B Ecommerce Brand
A B2B store with severe faceted navigation crawl loops, parameter-heavy duplicates, and poor Google indexation metrics hurting organic keyword rankings.
Implemented customized canonical rules, mapped structured index templates, set up parameter handling in Search Console, and configured programmatic JSON-LD schemas.
