Platform Rescue is an enterprise performance modernization project transforming bloated, slow legacy WordPress/Divi websites into headless, sub-second Next.js 15 architectures.
The Problem: The legacy production site was throttled by 42 unoptimized third-party plugins, bloated DOM hierarchy (>4,200 nodes), and a 6.8s Mobile LCP score, killing conversion rates and hurting SEO rankings.
The Solution & Architecture:
Headless Migration: Migrated frontend to Next.js 15 App Router with Tailwind CSS while decoupling the CMS via high-speed GraphQL/REST endpoints.
Sub-Second Core Web Vitals: Implemented aggressive image optimization, zero-layout-shift (CLS) component architecture, and Edge Caching via Vercel Edge Network.
Infrastructure Cost Reduction: Replaced heavy PHP server instances with serverless static generation (SSG/ISR), drastically reducing hosting bills.
Key Metrics & Impact:
Mobile LCP slashed from 6.8s down to 0.72s (Sub-Second Load).
Perfect 100/100 Google Lighthouse Core Web Vitals score.
68% drop in cloud infrastructure and compute costs.
