About this gig

Slow pages lose visitors and sales. Broken features lose trust.


I'll find what's slowing or breaking your website and fix it, with before-and-after proof.


Speed optimization

  • Google PageSpeed, GTmetrix and Core Web Vitals (LCP, CLS, INP)
  • Image compression, WebP, lazy loading
  • Caching, CDN (Cloudflare), minify CSS/JS, remove render-blocking code
  • Database and plugin cleanup


Bug fixing

  • PHP, JavaScript and console errors
  • Broken layouts, forms, menus, checkout or mobile issues
  • White screen, critical errors, plugin conflicts


Audit fixes

  • Google Search Console, Lighthouse, Ahrefs or Semrush audit issues
  • Broken links, redirects, missing meta tags, mixed content (SSL)


Platforms: WordPress, WooCommerce, Elementor, Shopify, HTML, React, Next.js.


I always back up your site first, so nothing is lost.

Hi, I'm Fernando, founder of CrestLabs, a web and mobile app development studio. Since 2016 I've built fast, modern websites and apps for clients in the US, UK and Australia. I work with Next.js, React, WordPress/WooCommerce, Laravel and Firebase, and I handle everything from landing pages and business sites to online stores, admin dashboards and Android apps. Every project is mobile-friendly, SEO-ready and built for speed. I communicate clearly, deliver on time and offer support after launch. Message me and let's build something great together.
