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.

- 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

Audit fixes

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.

FAQ
Can you guarantee a 100 PageSpeed score?
No one honestly can, since hosting, theme and third-party scripts affect it. I aim for 90+ on desktop and a clear mobile improvement, and show before/after results.
Will my design change?
No. Speed work keeps your design exactly the same.
What if the bug can't be fixed?
I'll tell you before starting, or Fiverr refunds you in full.
Do you back up my site first?
Yes, every time, before any change is made.
Do I need to share hosting access?
For speed work, usually yes (caching and server settings). Please share it only through the Fiverr order page.
