I will fix your slow website speed
Zubair-hussain
About this gig
Is your website slow? You are losing visitors, sales and your Google ranking every single day it stays that way.
I am a full stack developer working with Next.js, React and Node. I make slow websites load fast and pass Google Core Web Vitals.
What I fix
Slow loading pages and high LCP
Layout shift (CLS) and input delay (INP)
Heavy, uncompressed images
Render blocking CSS and JavaScript
Missing caching, compression and CDN
Bloated third party scripts
What you get
A real before and after PageSpeed report
A genuine score improvement, not a screenshot trick
Nothing broken. I test every page before delivery
Clear notes explaining every change I made
Works with: Next.js, React, custom HTML and JavaScript sites.
Every hour your site loads slowly is a customer choosing someone else.
Send me your URL before you order. I will run a free check and tell you honestly what score I can get you and which package you need. No pressure, no sales pitch.

FAQ
Will you break my website?
No. I take a full backup before I touch anything, and I test every page after optimization. If anything looks off, I fix it before delivery.
Can you guarantee a 90+ score?
I guarantee a large, visible improvement. A 90+ score also depends on your hosting and your theme, so send me your URL first and I will tell you honestly what is achievable before you order.
What do you need from me?
Your website URL and access to your hosting, repo or CMS. That is it. I only touch what is needed for speed.
How long does the improvement last?
Permanently, unless you later add heavy scripts, plugins or unoptimized images. I will show you what to avoid.
Do you work with WordPress or Shopify?
My focus is Next.js, React and custom coded sites. Message me with your platform and I will tell you straight if I am the right fit.
