Hi there, I am a web developer with extensive experience in performance optimization and a deep understanding of Google’s Core Web Vitals. I can help you achieve measurable improvements in your page load speeds by addressing your JavaScript bottlenecks directly. My approach to this project will focus on the three key areas you identified. I will minify your existing JavaScript to reduce file sizes, audit your codebase to strip out unused scripts that are bloat, and implement strategic deferring to ensure your main thread remains unblocked for a faster First Contentful Paint. Since you aren't using specific frameworks, I will utilize vanilla optimization techniques to ensure the solution is lightweight and maintainable. In previous projects, I have successfully moved sites from "Poor" to "Good" ratings in Search Console by focusing on script execution time and Largest Contentful Paint. I use tools like Lighthouse and PageSpeed Insights to track progress, and I will provide you with a "Before and After" report so you can see the tangible impact on your metrics. I am ready to start immediately and can ensure a clean, efficient delivery without breaking your site's functionality. I would be happy to share examples of my previous optimization work and discuss how we can get your site running at peak performance.

Hi, Perfect—this is exactly the kind of performance tuning that delivers real, measurable gains when done properly. I’ve optimized multiple sites (vanilla JS and frameworks) where Core Web Vitals improved significantly by cleaning up JS and restructuring load strategy. I’ll audit your site (Lighthouse + DevTools), then minify JS, remove unused code, and implement defer/async loading properly. I’ll also handle code-splitting (if applicable), reduce render-blocking scripts, and optimize execution time to improve LCP, FID/INP, and CLS. You’ll get before/after metrics with clear improvements in PageSpeed + Core Web Vitals. I focus on real performance gains, not superficial fixes. I can start immediately—quick question: is your site fully static or does it load any third-party scripts (analytics, chat, etc.) that we should optimize as well?

Hi, Slow Core Web Vitals almost always come down to JavaScript bloat, render-blocking scripts, and unused code sitting in the load path. I can audit and fix all three in one focused pass. Here is exactly what I would do: Audit every JS file using Chrome DevTools and Coverage tab to map unused code precisely Minify all JavaScript and combine where safe to reduce request count Move non-critical scripts to defer or async so the page renders without waiting Identify and remove or replace heavy third-party scripts causing the most damage to LCP and TBT Run PageSpeed Insights before and after so you have a clear before/after report showing the gains No guesswork. Every change is measured and documented. 12+ years optimising WordPress and custom sites means I have seen every common JS performance mistake. Render-blocking scripts and unused jQuery chunks are usually the biggest wins on sites without a specific framework. I will share the full audit findings before making changes so you approve what gets touched. Best regards, Krish

Hi — optimized a JS-heavy site recently where load time was stuck above 4s. The real issue wasn’t just size, it was blocking scripts. After removing unused code and deferring execution, we brought it under 2s and Core Web Vitals moved into green. For your site, I’ll audit all JavaScript first—identify unused bundles, inline what’s critical, and defer or async-load the rest. I’ll also break up heavy scripts, eliminate render-blocking resources, and ensure everything loads only when needed. The goal is faster First Contentful Paint and smooth interaction, not just smaller files. You’ll get measurable improvements in load speed, cleaner JS execution, and better Core Web Vitals across pages. Ready to start now. Want me to run a quick audit and show before/after opportunities first? — Danish
