My corporate-style site is sitting at an unimpressive 70 on Google’s mobile PageSpeed Insights across every page. The target is a stable 90 or better without sacrificing design integrity or functionality. Code optimization is the focal point, so the job is entirely front-end and asset related—no server moves or hosting changes. What needs to happen: trim the fat in CSS and JavaScript, remove or defer anything that blocks first paint, and streamline the asset loading sequence so Core Web Vitals (LCP, FID, CLS) improve in tandem with the overall Lighthouse performance score. Think clean bundling, intelligent splitting, async/defer tactics, critical CSS inlining, and well-configured cache headers. Images and server tuning are already handled elsewhere; the win must come from smarter code delivery. Deliverables • A repeatable process (build script or documented steps) that pushes every public page to 90+ mobile in Google PageSpeed Insights • Before / after Lighthouse reports for at least the home page and two internal pages • A concise changelog of all code adjustments so future deployments remain compatible Acceptance criteria: the 14 supplied URLs must score 90 or above on mobile in PageSpeed Insights under an incognito, throttled “mobile” test using the default settings, and all visual/UI features must remain intact. Tools widely welcomed include Lighthouse, Webpack/Rollup, PurgeCSS, and any in-browser dev tooling you prefer; feel free to suggest equivalents if they achieve the same outcome.

The trickiest part of pushing a corporate-style site to 90+ mobile PageSpeed without touching hosting is executing critical CSS inlining and intelligent JS splitting without triggering layout shifts (CLS) or breaking UI functionality. Since your code delivery is the focal point, I will focus entirely on trimming the fat in CSS and JavaScript, deferring render-blocking assets, and optimizing the asset loading sequence to improve LCP, FID, and CLS in tandem. My core stack includes HTML, CSS, PHP, JavaScript, and jQuery, allowing me to go beyond templates and deliver custom solutions when needed. I am well-equipped to handle this front-end and asset-related optimization using tools like Webpack, PurgeCSS, and Lighthouse to achieve the stable 90 or better score across your 14 supplied URLs. I will deliver before/after Lighthouse reports for the home page and two internal pages, a concise changelog, and a repeatable process so future deployments remain compatible. My bid is $25 with a delivery time of 1 days. Let's get started—feel free to reach out so we can review the site.

Going from 70 to 90+ on mobile with images and server already handled means the remaining cost is almost entirely main-thread work and render-blocking requests, so I'd start by pulling the Lighthouse treemap and long-task breakdown for your 14 URLs to see exactly which bundles and third-party scripts are eating the budget. From there: PurgeCSS against real rendered markup to strip unused rules, per-template critical CSS inlined with the rest loaded async, route-level code splitting so internal pages don't ship the homepage's JS, third-party tags deferred or moved behind interaction, preload/preconnect on the LCP resource, and explicit dimensions on any element causing shift. Everything lands in a repeatable build script rather than one-off edits, with before/after reports and a changelog so future deploys stay compatible. Send me the URLs and repo access and I can start immediately.

Hi, I'm Denis. I've helped sites improve their Lighthouse scores by tightening up the front-end asset pipeline without changing the visual design. Your site is already in a good place with images and server setup handled, so the bottleneck is likely in how CSS and JavaScript are bundled, loaded, and deferred. The fastest wins usually come from critical CSS inlining, code splitting, and reordering resource fetch timing. I'll run an audit on the 14 URLs, identify what’s blocking first paint or delaying interactivity, then implement a repeatable build process using Rollup or Webpack with PurgeCSS and proper cache headers. I'll keep a changelog so future deployments stay compatible and provide before/after Lighthouse reports so you can verify the 90+ mobile score. I can start working right away. Let's connect and discuss the details. Thanks, Denis.

Hi there, Your corporate site sits at 70 on mobile PageSpeed and needs a stable 90+—without server moves, so the win has to come entirely from front-end code delivery. The tricky part is applying aggressive optimizations like critical CSS inlining and code splitting across all 14 pages without breaking visual consistency or functionality. I would start by auditing all 14 URLs to identify blocking scripts and render-critical CSS, then implement a build process with Webpack or Rollup for bundling and splitting, inline critical CSS, defer non-essential JS, and set proper cache headers. I would test each page with Lighthouse throttled mobile and document the repeatable steps. I have optimized front-end performance for corporate sites, using Lighthouse and bundling tools to push scores into the 90s while preserving design. 1. Do you currently have a build pipeline (Webpack, Gulp, etc.) in place, or are we working with raw CSS and JS files that need a new setup from scratch? 2. For those 14 pages, are they mostly static templates with similar CSS/JS, or do they vary significantly in content and component loading patterns? Reply with those and I can lay out the optimization plan. Best regards, Opeyemi

Hi, I can get all 14 supplied URLs to 90+ mobile PageSpeed without changing design or functionality. The approach hinges on whether each page is static or server-rendered. If static, I'd extract critical CSS per template at build time. If server-rendered, I'd inline critical CSS in the server response and defer the rest. I'd run PurgeCSS against generated classes to drop unused CSS, split vendor chunks from route code, and mark non-critical scripts async or deferred while lazy-loading below-the-fold components. What you didn't list is CLS from late-loading fonts and third-party scripts, so I'd preload fonts and reserve their space to keep the score stable across runs. You'll get a documented repeatable build script, before/after Lighthouse reports for the home page and two internal pages, and a changelog so future deploys stay compatible. I can prove the pipeline on one URL first and let you run the default mobile test yourself. Send me repo access and the 14 URLs and I can start today.

Absolutely, this is the kind of performance rescue that should feel invisible to users and very visible to Lighthouse. The focus is clear: keep the design intact, keep functionality intact, and get all 14 pages to 90+ on mobile under real throttled conditions. I’d tackle this from the delivery layer: CSS/JS trimming, smarter splitting, aggressive defer/async handling, critical CSS inlining, and a clean loading sequence so first paint and Core Web Vitals improve together. I’ll also provide a repeatable workflow, so future deploys don’t accidentally undo the gains. That means a practical build process or documented optimization steps, plus before/after Lighthouse evidence for the home page and two internal pages, and a concise changelog that your team can keep using. If the current bundle structure is fighting performance, I’ll make it behave. If it’s just carrying too much baggage, I’ll help it travel lighter. Delivered cleanly, documented clearly, and tuned for lasting compatibility.

Hi, pushing 14 pages from roughly 70 to a repeatable 90+ is less about one Lighthouse trick and more about removing the same render blocking and execution bottlenecks across the shared frontend stack. I’d profile each template, then reduce unused CSS and JavaScript, inline only true critical CSS, split and defer nonessential code, fix asset priority, and validate LCP, CLS, and interaction performance after every change. I’ll also leave a repeatable optimization workflow, before and after Lighthouse reports for the required pages, and a changelog so future deployments do not undo the gains. I’m comfortable working with Lighthouse, DevTools, Webpack or Rollup, PurgeCSS, async and defer strategies, and frontend performance debugging while preserving the current UI exactly, thanks.

Hi there, You've made it clear the only acceptable outcome is a mobile PageSpeed of 90+ for all 14 URLs, with zero compromise to design or UX, and no server/hosting tweaks. My approach would target code and asset delivery only: trimming unused CSS/JS, deferring non-critical scripts, inlining critical CSS, and restructuring bundles for smarter loading via Webpack or Rollup. I'll generate both build scripts and step-by-step documentation, so your team can repeat the process on future releases. Before/after Lighthouse reports for three pages and a changelog will be delivered as requested. I'll honor your visual integrity constraint by testing on incognito, throttled mobile and flagging any risky adjustments for your review before they go live. No changes will be made to images or server config, as you specified. One thing often missed is the impact of third-party scripts and custom fonts on FID and CLS, so I'll include a review of their loading patterns to catch any hidden delays. I'm motivated to build a strong reputation on results like this, and can get started as soon as I have access to the codebase and the 14 URLs list. Is there a staging environment available for safe testing? Best regards, Nataliya H.
