About this gig

A slow website loses visitors, sales and Google rankings. Core Web Vitals (LCP, CLS, INP) are part of how Google evaluates pages, and visitors on mobile rarely wait for a page that feels slow.

I am a web developer and I speed up your site by fixing what actually slows it down, not by stacking more plugins.

What I optimize

  • Images: compression, modern formats (WebP, AVIF), correct sizes, lazy loading
  • Caching and minification of CSS and JavaScript
  • Render-blocking scripts, fonts and third-party tags
  • Layout shifts (CLS) and slow interactions (INP)
  • Database cleanup and server response time

How it works

  • You send the URL and access to your CMS or code
  • I measure with PageSpeed Insights and Lighthouse before starting
  • I apply the fixes and test that nothing breaks
  • You get before and after scores and a list of every change

WordPress, WooCommerce, Shopify themes, Next.js and plain HTML. Everything is written and asynchronous, no calls needed. Scores depend partly on hosting and third-party scripts, so I tell you honestly what is realistic before I start.

Respect third-party rights

Please be aware that it is against Fiverr's policies for sellers to include themes, templates, or any other elements that infringe third-party rights or applicable laws in the delivered work. Read more about in our Guide to Responsible Digital Creation.

I build websites that get found and fix the ones that fall short: Google rankings, visibility in AI answers like ChatGPT and Perplexity, fast loading, and accessibility under WCAG 2.2 and the European Accessibility Act. I run my own accessibility testing software with six test layers, so every fix is measured before and after. What I do: - Websites and landing pages - SEO and AI search optimization - WCAG audits and code fixes for Shopify, WordPress and React - EAA accessibility statements - Speed optimization and maintenance Freelancing since early 2024. Fixed prices, no overlays.
