You built your site with Next.js for performance - but if Google PageSpeed still shows red and yellow, somethingโs slowing you down. Poor Core Web Vitals (LCP, INP, CLS) mean more than bad scores - theyโre costing you visitors, SEO rankings, and conversions.
Iโm K M Foysal, your Next.js Speed Optimization Specialist and Google Lighthouse speed optimization expert Next.js. I help websites achieve real, measurable speed improvements - not just temporary boosts. As a Google PageSpeed optimization expert Next.js and Next.js Core Web Vitals expert, I make your site truly fast.
How I do it:
โโข Full Core Web Vitals audit (LCP, INP, CLS)
โโข Optimize images, fonts & caching using next/image & next/font
โโข Code splitting & bundle optimization
โโข Fix layout shifts and slow render issues
โโข Before vs. After performance report
Work with a Next.js Core Web Vitals specialist who understands every millisecond matters. Letโs make your Next.js site load fast, rank high, and convert better.

K M works on your project following the steps below.
Revisions may occur after the delivery date.
Phase 1: Deep Audit & Diagnosis
Start as a Google Lighthouse speed optimization expert Next.js by performing a Google PageSpeed CWV audit. Pinpoint root causes of slow loading, like bundle bloat and inefficient rendering, using technical analysis tools.
Phase 2: Execution & Fixes
As a Next.js speed optimization specialist and Core Web Vitals expert, I fix LCP/TTFB via caching/SSR and optimize INP with code splitting. I ensure zero CLS and proper script loading, transforming the app into a high-performance site.
