Our Hyper-Specialized Focus

We optimize the metrics that matter: Core Web Vitals measured with real user data (CrUX)

LCP Optimization

Largest Contentful Paint · Target: ≤ 2.5s

We optimize your largest content element to render instantly through advanced image optimization, resource prioritization, preloading strategies, and TTFB reduction.

INP Optimization

Interaction to Next Paint · Target: ≤ 200ms

We eliminate JavaScript bottlenecks, optimize event handlers, reduce main-thread blocking, and ensure instant response to user interactions.

CLS Optimization

Cumulative Layout Shift · Target: ≤ 0.1

We stabilize your layout by reserving space for dynamic content, optimizing font loading, and preventing unexpected shifts.

Our Battle-Tested Process

Proven methodology refined over 13+ years of performance optimization

1

Deep CrUX & Field Data Analysis

We analyze real user experience data from Chrome User Experience Report, not just synthetic lab tests. This reveals actual performance issues your users face across devices and network conditions.

2

Custom Optimization Blueprint

No generic solutions. We create a platform-specific roadmap targeting your unique bottlenecks—from render-blocking resources to database queries to third-party scripts.

3

Surgical Implementation

Expert implementation with zero downtime: image optimization (WebP/AVIF), JavaScript optimization, critical CSS inlining, server tuning, CDN setup—all tested in staging first.

4

Real User Monitoring & Validation

We validate improvements with CrUX field data, not just lab tests. You get detailed before/after reports showing real impact on actual users across all devices and locations.
