Fixing Critical Headless Next.js Engineers Bottlenecks
Root Cause: Bloated PHP plugins, unoptimized MySQL queries, and lack of edge caching causing 4.5+ second load times on mobile.
Root Cause: Cache invalidation failing between headless CMS editors and statically generated production pages.
Root Cause: Dynamic banner injection, unconstrained web fonts, and missing media aspect ratios causing content to jump during loading.
