I will fix speed and SEO audit and fix for an existing react
Sam M
About this gig
A slow site loses visitors and Google rankings. I find exactly what's making yours slow, and fix it.
I'm a front-end developer with 4+ years in React and Next.js, currently working with Klipboard, a UK company whose business software is used in over 70 countries. On a high-traffic news platform, I cut load time by 50% and infrastructure costs by 30%.
I start by measuring Lighthouse, Core Web Vitals, bundle analysis so you get real numbers instead of guesses. Then I show you which changes will make the biggest difference before I touch anything.
What usually causes it: oversized images, bloated JavaScript bundles, render-blocking resources, unnecessary re-renders, missing code splitting, and the wrong rendering strategy for the page. You get a before-and-after report with real measurements, so you can see exactly what changed.

I build front ends for ERP, inventory, and BI dashboards — the data-heavy interfaces most React devs avoid. Currently Contracting at Klipboard (UK), building their ERP platform in React/TypeScript, used in 70+ countries. Also: a multi-tenant dashboard for Ajza (Saudi Arabia) and a front-end rebuild for a national news platform in Egypt. On one high-traffic platform I cut load time 50% and infrastructure costs 30%.
Stack: React, Next.js, TypeScript, Redux Toolkit, React Query, Tailwind, shadcn/ui, Material UI, REST + GraphQL, Jest/Vitest.

FAQ
Can you guarantee a Lighthouse score of 100?
No, and be cautious of anyone who does. Some scores depend on third-party scripts, ad networks, and hosting that I don't control. I'll tell you what's achievable after the audit, and my before-and-after numbers show exactly what I delivered.
Will you break my site?
I work on a separate branch and never push directly to your live site. You review the changes and deploy when you're ready.
What if my site isn't React or Next.js?
Send me the URL first. I work in React, Next.js, and plain JavaScript. WordPress, Shopify, and Wix sites need a different specialist, and I'll say so rather than take the job.
Do you need access to my code?
Yes, for the fix tiers. A GitHub invite with read access is enough to start. The audit-only tier needs just your URL.
Will the improvements last?
The fixes are permanent, but adding heavy images or new third-party scripts later will slow things down again. My report explains what to watch for, and the monitoring add-on covers a follow-up check.
