I will audit and fix your website speed and core web vitals
Shakerullah
About this gig
Is your React or Next.js site losing visitors because it loads too slowly?
Google uses Core Web Vitals as a ranking factor, and slow sites lose visitors before they see your content. I specialize in performance audits and fixes for custom React and Next.js apps real code-level optimization, not generic plugins.
What I help with:
- Core Web Vitals (LCP, INP, CLS)
- Bundle size reduction & code splitting
- Image optimization (next/image, lazy loading)
- SSR/SSG tuning
- Caching (CDN, ISR, edge)
- Data fetching optimization
- Before/after performance report
Note: Fiverr's standard labels "Browser Caching," "Resize photos," "Minification," and "Database Optimization" translate to CDN/ISR caching, next/image optimization, bundle reduction, and data-fetching optimization for React/Next.js.
Built for: Custom React and Next.js apps marketing sites to SaaS dashboards.
How it works: Send your repo/URL I audit it I deliver the report or implement fixes you get a before/after comparison.
Want a diagnosis, or a fully optimized app? There's a package for both.

FAQ
Do you work with WordPress, Shopify, or Wix sites?
No — this gig is exclusively for custom React and Next.js applications. If your site is built on WordPress/Shopify/Wix, I won't be the right fit for this particular gig.
Do you need access to my code or repository?
Yes, ideally read access to your GitHub/GitLab repo. If that's not possible, a staging URL plus deployment details (Vercel, Netlify, custom server) works too.
What's the difference between the Basic package and the others?
Basic is audit-only — you get a full report identifying issues, but I don't implement any fixes. Standard and Premium include the actual implementation.
I see package features like "Database Optimization" and "Browser Caching" — do you work with databases directly?
Those are Fiverr's standard category labels. For React/Next.js apps, they translate to data-fetching/API query optimization and CDN/ISR/edge caching — not literal database or browser-level work.
Can you guarantee a 90+ Lighthouse score?
I optimize aggressively, but final scores depend on factors outside code — hosting/server location, third-party scripts, and image/content weight. I'll get you as close as technically possible and explain any remaining constraints.
What if my app uses a specific framework feature (e.g., App Router, Server Components, ISR)?
No problem — I work with both Pages Router and App Router, and regularly optimize Server Components, streaming, and ISR/SSG setups.
How many pages/routes does "up to 5 pages" actually cover?
Any 5 distinct routes in your app (e.g., homepage, dashboard, product page, etc.) — not 5 components on the same page.
Can I add more pages beyond my package limit?
Yes, as a custom order or extra — let me know your total route count before ordering so I can quote accordingly.
Do you provide before/after proof?
Yes — every package includes a before/after performance report using Lighthouse/PageSpeed Insights so you can see the measurable improvement.
