Core Web Vitals Optimization

Stop losing customers to a slow website.

A 1-second delay in page load time reduces conversions by 7%. I rewrite bloated frontends and configure edge networks to guarantee sub-2-second load times.

Why your current setup is failing Core Web Vitals.

Bloated JavaScript

Most themes load every single script on the initial page load. We defer non-critical JS and implement strict code-splitting to free up the main thread.

Unoptimized Assets

Serving 5MB uncompressed PNGs kills mobile performance. We migrate assets to modern formats (WebP/AVIF) and serve them via advanced Edge CDNs.

Third-Party App Bloat

Shopify and WordPress plugins inject tracking codes that block rendering. I audit, consolidate, and asynchronously load your marketing stack.

Same pattern, different platform.

The Shopify example above isn't a one-off — here's a named, linkable case.

WooCommerce, Norway

MerkBart moved off shared hosting onto AWS Lightsail with S3 + CloudFront for uploads.

The admin panel used to freeze for minutes on every order with multiple logo uploads. Now it doesn't freeze at all, and pages load roughly 4× faster.
