I will fix core web vitals and speed up your nextjs website


About this gig
Is your Next.js or React website losing traffic because it loads too slowly?
I'm Andrea, a frontend developer specializing in high-performance web applications. I don't rely on plugins I analyze your actual codebase and fix the root causes of poor performance.
My portfolio speaks for itself: I consistently deliver 92100/100 Mobile PageSpeed scores, resulting in measurable improvements in lead generation and inbound traffic for my clients.
WHAT I FIX:
Core Web Vitals: LCP, CLS, and INP
Code splitting and component lazy loading
Next/Image configuration and font subsetting
Third-party scripts (Analytics, Meta Pixel) deferred without data loss
Vercel/CDN edge caching and deployment optimization
WHAT YOU RECEIVE:
A significantly faster, more stable website
Detailed Before & After PageSpeed Insights report
Cleaner, more maintainable codebase
Start with the Basic audit if you want a risk-free look at your site before committing to full optimization. The roadmap I provide will show you exactly what needs fixing and why.
Please message me with your site URL before ordering so I can run a quick preliminary check.
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.

FAQ
Do you need access to my source code?
Yes. Performance optimization happens at the code level — I need read access to your Git repository. For Standard and Premium, write access is required to implement the fixes directly.
What if my site is not built with Next.js?
I specialize in Next.js and React. If your site runs on a different framework (Nuxt, Remix, plain React), message me first — I can evaluate it case by case. WordPress and Wix are not supported.
Can you guarantee a specific PageSpeed score?
I can't guarantee exact scores — they depend on your hosting, third-party scripts, and content. What I guarantee is a measurable improvement with a documented Before & After report on every order.
What is included in the Basic audit?
A full PageSpeed and Core Web Vitals analysis, quick fixes (images, caching, fonts), and a written roadmap listing every issue found with priority and estimated impact. Delivered in 2 days.
Will the optimization break my website?
No. I work on a separate branch and test all changes before delivery. You review and approve before anything goes to production. For Standard and Premium, I include a rollback plan.
Do you provide ongoing support after delivery?
Each package includes revisions within the delivery window. For ongoing maintenance, message me — I offer monthly retainer arrangements for clients who need continuous performance monitoring.

Andrea quickly and competently understood my request regarding the implementation of the Meta Pixel CAPI in Next.js and delivered a clean solution. In addition, he clearly explained which adjustments I still needed to make on my side and how I could verify them. I am very satisfied with the collaboration.

Andrea ha svolto un ottimo lavoro nell ottimizzare il nostro sito web. Da un analisi preliminare ha individuato i problemi maggiori e risolti in pochissimo tempo, dimostrando esperienza nelle tecnologie segnalate. Avevamo concordato l’ottimizzazione di due pagina ma è andato oltre migliorando tutto il sito. Consigliato!
