The Challenge & Context

The Problem

Lumina Living's store was burdened with 42 active WordPress plugins, causing frequent 504 Gateway Timeouts during promotional launches and poor Google Core Web Vitals scores that penalized their paid search campaigns.

Project Constraints

Key Constraints

  • Over 4,500 SKU variants with historical order history had to be migrated cleanly
  • Marketing team required an intuitive visual content builder without touching code
  • Existing SEO URL structure and 10,000+ indexed backlinks needed 100% preservation
Solution Architecture

Technical Approach & Execution

Decoupled the frontend using Next.js on edge infrastructure with Sanity Studio for structured storytelling and a streamlined headless commerce backend.

Phase 01

Content & Catalog Separation

Migrated product editorial content into Sanity CMS, providing marketing with instant visual previews and reusable page builder blocks.

Phase 02

Edge Caching & Dynamic Cart Architecture

Configured Static Site Generation (SSG) with On-Demand Incremental Static Regeneration (ISR) for instant catalog browsing alongside a serverless cart.

Phase 03

Automated 301 Redirect Mapping

Audited and scripted over 12,000 legacy URLs with regex redirect fallbacks, ensuring zero 404 errors post-launch.
