I will optimize your next js or react website speed to 90 plus lighthouse score
Ehtisham H
About this gig
A slow site loses you money: visitors leave, Google ranks you lower, and ads cost more per conversion. I make React and Next.js sites fast, then prove it with before/after Lighthouse and Core Web Vitals reports.
Real results, not promises: 40% Core Web Vitals improvement across three live financial platforms at Gala, and a 35% LCP reduction on a Next.js platform serving 2M+ members, delivered through SSR and ISR caching. 5+ years in production React and Next.js.
What I optimize:
- Images: modern formats, lazy loading, correct sizing
- JavaScript: code splitting, dead-weight removal, bundle analysis
- Fonts and layout shift (CLS), render-blocking resources
- LCP, INP and CLS brought into the green
- Caching, CDN and ISR setup (Vercel, Netlify, Cloudflare)
- Slow API waterfalls and server response time
What you get:
- Before/after Lighthouse + Core Web Vitals report
- Clean fixes in your own codebase, no plugins or hacks
- Every change explained in plain English
Works with Next.js, React, Vite and Node backends on any hosting.
Not sure what is slowing your site? Send me the URL and I will run a free mini-audit before you spend anything.

FAQ
Do you guarantee a 90+ Lighthouse score?
On most React/Next.js sites, yes. If heavy third-party scripts (ads, analytics, chat widgets) make 90+ impossible, I'll tell you the realistic ceiling BEFORE you order, from your free mini-audit.
Will you break my site?
No. I work on a branch, you review changes before they go live, and every change is documented. Nothing is deployed without your approval.
Mobile or desktop score?
Both are in the report. Mobile is the one Google cares about, so that's what I optimize for first.
What do you need from me?
Your site URL and code access (GitHub invite or zip). For the Basic audit, just the URL.
My site is WordPress/Shopify, can you help?
This gig is specialized for React, Next.js and JavaScript apps. That focus is exactly why I get results on them.
How do I know it worked?
You get side-by-side before/after Lighthouse and PageSpeed Insights reports, plus a summary of every change and why it helped.
