About this gig
Is your Next.js app losing users to slow load times?
A 1-second delay can drop conversions by 7%. Poor LCP or CLS flags don't just hurt Core Web Vitals, they hurt your SEO ranking too. As a Next.js specialist, I optimize code, not just images, turning failing scores (25-40) into elite performance (90+ targeted, verified with a fresh Lighthouse audit at delivery).
Why your site is slow: Huge bundles, JS hydration lag, unoptimized media, and render-blocking scripts.
My Professional Fixes:
- Next.js Tech: Proper next/image, font, and script logic
- Vitals Mastery: Technical fixes for LCP, CLS, and INP scores
- Bundle Stripping: Removing heavy JS via @next/bundle-analyzer
- RSC Migration: Moving to Server Components for 0kb client JS
- Smart Caching: Implementing ISR, SWR, and Edge strategies
Recent result: took a client's Next.js app from a 25 performance score to 91, cutting Largest Contentful Paint from 20.7s to 1.7s and blocking time from 16s to 100ms (Lighthouse-verified, NDA client).
I work directly in your codebase, not plugins, and test every feature so nothing breaks.
React and Next.js only. Vercel, AWS Amplify, and self-hosted deployments welcome.

FAQ
Why is my Next.js site slow even though it’s a modern framework?
Even with Next.js, performance can drop due to unoptimized images, heavy third-party scripts (like Google Analytics or Ads), or large npm packages bloating your bundle. I use the Next.js Bundle Analyzer to find these "hidden" speed killers and optimize your code for a 90+ PageSpeed score.
Will my website’s functionality break after optimization?
Absolutely not. Unlike generic "speed hacks," I perform code-level optimizations tailored to React/Next.js. I test every feature (forms, buttons, navigation) after the changes to ensure your site stays 100% functional while becoming lightning-fast.
What type of websites do you optimize?
I optimize React and Next.js applications only. This includes frontend apps built with JavaScript or TypeScript and deployed on platforms like Vercel.
Do you work with Vercel deployments?
Yes. I optimize Next.js performance on Vercel, including build optimization, runtime performance, and production-related speed issues.
Do you provide a performance report?
Yes. After completing the order, I can share before/after Lighthouse results and explain what was optimized in simple terms.
Will this improve my Google Core Web Vitals?
Yes. My optimization focuses on improving Core Web Vitals, including LCP, CLS, and INP, which directly impact user experience and search engine performance.
