Every front-end application we ship is engineered to exceed Google’s strict Core Web Vitals thresholds, maximizing search engine ranking and user conversion rates.
LCP (Largest Contentful Paint)
Target: < 1.2 SecondsMeasures perceived loading speed. We achieve sub-second LCP via server-side rendering (Nuxt SSR), asset preloading, and edge CDN distribution.
INP (Interaction to Next Paint)
Target: < 50 MillisecondsMeasures page responsiveness. We eliminate JavaScript main-thread blocking through web workers, lightweight component trees, and debounce handlers.
CLS (Cumulative Layout Shift)
Target: 0.00 (Zero Shift)Measures visual stability. We enforce explicit image aspect ratio dimensions, font font-display swapping, and layout reservation containers.
FCP (First Contentful Paint)
Target: < 0.6 SecondsMeasures the time until the first visual DOM node renders on the visitor’s screen across 3G/4G/5G mobile networks.

When Custom Web Application Engineering Beats Off-The-Shelf CMS & Website Builders
CMS platforms (WordPress, Shopify, Webflow) are great for basic marketing sites. But when your web application requires sub-second reactive state, complex database schemas, multi-tier user permissions, or high-volume transactional flows, template bloat and fragile plugins will throttle your user conversions.
