I will optimize website speed and core web vitals score
Mezbibur Rahman
About this gig
A slow website quietly drives away visitors and drags down your Google ranking - every extra second cuts conversions. I make sites load lightning-fast and turn your Core Web Vitals green.
Performance is my specialty: I have cut load times by 40% on platforms serving millions, optimizing real-world Core Web Vitals at scale.
What you get:
- A clear speed audit with before/after scores
- - Higher Lighthouse and PageSpeed scores
- - Core Web Vitals (LCP, CLS, INP) fixed and in the green
- - Image, caching, code-splitting and bundle optimization
- - Faster load times that lift SEO and conversions
How it works: 1) Share your site URL. 2) I audit and optimize. 3) You get a faster site plus a clear report.
Works great for Next.js, React and most modern sites - message me your URL for a quick assessment.
