Next.js Speed Optimization Boost

I run a production [login to view URL] site that needs speed improvement. I want both the mobile and desktop scores pushed to 92 + while every current feature keeps working exactly as it does today and I don't want the UI to get messed up on the various breakpoints. Do a good job at a good price and this can become a regular project with many sites needing the work. A fresh Lighthouse or PSI report will show the main culprits: render-blocking and unused JavaScript, layout shifts, and other script-related bloat. Images are already compressed, so the gains have to come from smarter code-level work—think granular code-splitting, dynamic imports, removing legacy bundles, fixing CLS, preloading critical assets, and confirming headers for compression and caching are spot-on. I haven’t implemented any significant performance optimizations yet, so you’ll be starting from a clean slate. Google PageSpeed Insights is the reference tool for measuring success, but you’re free to cross-check in Lighthouse or WebPageTest if that helps you track your progress. Deliverables (acceptance criteria) • Mobile and desktop PSI scores of at least 92 on the live domain • Before-and-after PSI screenshots plus the JSON export for transparency • A concise list of code changes or config tweaks, clearly commented or documented in a short README • No visual regressions or broken functionality—Core Web Vitals must improve without side effects The stack is [login to view URL] (latest stable), React, Webpack, and Vercel hosting. If you’re comfortable profiling bundles, pruning unused code, and tightening Web Vitals, I’d love to see what you can do.
