Speed
Optimisation

Page speed is not a technical vanity metric — it is a direct revenue driver. A 1-second delay in load time correlates with a 7% reduction in conversion rate. We close that gap with surgical precision.

We audit your site against PageSpeed Insights, Lighthouse, and WebPageTest. We identify every millisecond of waste and systematically eliminate it.

Core Web Vitals Optimisation

We systematically optimize LCP, CLS, and INP to hit top-tier scores. Google's ranking signals and your users' experience both improve in parallel.

Image Pipeline Engineering

Next-gen format conversion (WebP, AVIF), lazy loading, responsive srcsets, and CDN delivery. Images are always optimally sized, optimally formatted, and optimally delivered.

JavaScript Optimisation

Code splitting, tree shaking, deferred loading, and bundle analysis. Every unnecessary kilobyte of JavaScript is identified and eliminated from the critical path.

Server-Side Rendering

For maximum SEO and performance, we implement SSR where appropriate. The browser receives ready-to-render HTML — not an empty shell waiting for JavaScript.

Caching Architecture

Multi-layer caching: browser cache, CDN cache, and server-side cache configured precisely. Your server handles a fraction of the requests it would otherwise serve.

Third-Party Audit

We audit every third-party script, analytics tag, and embedded resource. Non-essential scripts are deferred or eliminated. Only what earns its weight survives the audit.
