Core Web Vitals
LCP from 8s to 3s at Swift/JBS. Priority hints, fetchpriority, edge caching, and streaming SSR working together.
Faster pages, better rankings, higher conversion. Performance and technical SEO as first-class engineering.
At Swift/JBS, I inherited an e-commerce platform with 8s LCP and Lighthouse below 40. I treated performance as an engineering project — not last-minute polish. The result: −62% LCP, +38% organic traffic, 71% smaller bundle.
LCP from 8s to 3s at Swift/JBS. Priority hints, fetchpriority, edge caching, and streaming SSR working together.
Score maintained above 95 in production for consecutive months — not a pretty screenshot from staging.
URL design, hreflang across 3 languages, canonicalization, dynamic sitemaps and schema.org — SEO built into the code, not bolted on later.
SSG for the blog, SSR for catalog, ISR for dynamic pages — every route with the strategy that makes sense for the product.
From 1.2MB to 350KB. Code splitting, tree shaking, partial hydration, and RSC as engineering tools — not buzzwords.
−62% LCP translated into +12% conversion on product pages. Performance pays the bills.
