Capabilities_

// 01

LCP Optimization

Critical CSS inlining, resource hints, font subset/swap, hero image preloading, and server-side render optimization.

// 02

CLS Stabilization

Reserve space for images/ads/embeds, avoid late-injected DOM, font-display strategies that do not shift layout.

// 03

INP / Interaction Latency

Defer non-critical JS, code-split aggressively, debounce expensive handlers, isolate main-thread work to web workers.

// 04

Image Pipeline

AVIF/WebP fallbacks, responsive srcset, lazy-loading, CDN edge resizing, and aspect-ratio reservation.

// 05

Real-User Monitoring

Web Vitals JS reporting to GA4 / Datadog with p75 dashboards. Synthetic Lighthouse runs in CI on every PR.

// 06

Server Response Tuning

OPcache, Redis caching, query plan analysis, full-page cache for anonymous traffic, edge caching with stale-while-revalidate.
