About this gig
Is your Next.js app slow, scoring red on PageSpeed, or getting penalized in Google rankings?
I'll diagnose exactly what's killing your performance and fix it with measurable before/after Lighthouse scores.
Common issues I fix:
- Poor LCP (Largest Content ful Paint) slow above-the-fold load
- High CLS (Cumulative Layout Shift) elements jumping around on load
- Unoptimized images (missing next/image, no lazy loading, wrong formats)
- Render-blocking JavaScript and CSS
- Inefficient API calls, waterfall fetching, missing caching
- Bundle size bloat unused packages, missing code splitting
- Missing or broken SSR/SSG/ISR configuration
What you receive:
- Full Lighthouse audit report (before & after)
- Fixed, optimized codebase pushed to your repo
- Written summary of every change made and why
I don't just make the score look good. I fix the actual bottlenecks so your real users feel the difference faster loads, less bounce, better ranking.
Before you order: Share your Page Speed Insights URL or Lighthouse report in a message. I'll review it and tell you exactly what I'll fix before any money changes hands.

FAQ
How much can you improve my score?
It depends on your current issues, but most sites I work on see a 30–60 point Lighthouse improvement. I'll give you a realistic estimate after reviewing your site before you order.
Do you need access to my codebase?
For the Standard and Premium tiers, yes. You can share access via GitHub or a private repo. A read-only fork works too — I'll submit a pull request with all changes for your review.
My site is on Vercel / Netlify. Does that matter?
No, I work with all deployment platforms. I'm also familiar with Vercel's edge config and image optimization settings specifically.
What if my score doesn't improve significantly?
I share the audit before starting work so you know exactly what to expect. I won't take an order I can't deliver on — if your bottleneck is server-side or infrastructure-level and outside my scope, I'll tell you upfront.
