I specialize in PrestaShop performance and Core Web Vitals, and can target 90+ PageSpeed on both mobile and desktop for your 8.2.1 store, focusing on real UX gains, not just lab scores. I’ve optimized multiple PrestaShop 1.7+ and 8.x shops, improving CLS, LCP, and INP by refactoring themes, slimming modules, deferring JS, optimizing images, and tuning servers/CDNs without breaking existing features. My approach would be an audit first (themes, modules, server, Lighthouse, CrUX), then a prioritized fixes list, staged implementation, and validation in PageSpeed and Search Console. I would love to chat more about your project!

@priyanshug777

Hi, I can help with this optimization project and I have strong experience with PrestaShop performance tuning, theme customization, module debugging, and Core Web Vitals optimization on production stores. Your bottlenecks are already well identified and the LCP issue appears heavily tied to the Leo Slideshow implementation (JS-injected hero image + missing fetchpriority/preload path). I would address this first because it is likely the largest contributor to the 20.4s mobile LCP. My approach would include: • Staging-first workflow with full rollback path • Leo Slideshow optimization (discoverable hero image, preload, fetchpriority, WebP, sizing fixes) • Critical CSS extraction and render-blocking CSS reduction • GTM cleanup/consolidation while preserving GA4 + Ads events • Non-blocking iubenda loading strategy maintaining Consent Mode v2 • Font consolidation/subsetting (FA / Line Awesome / eicons overlap removal) • JS debugging (Slick initialization issue, coverage cleanup) • Above-the-fold image optimization and lazy strategy review • Plesk/nginx tuning (compression, cache, OPcache, PHP-FPM review) I understand the “no regressions” requirement and would preserve: Checkout, PayPal, HeyLight, faceted search, GA4 events, Ads tracking, Leo modules, SEO URLs and redirects. Looking forward to reviewing the staging environment.

@ritus467

Many Thanks! Ritu

Hi there, You’re absolutely in the RIGHT PLACE. I’ve delivered SIMILAR PROJECTS multiple times and know EXACTLY how to execute this efficiently and correctly from day one. To lock down the SCOPE, TIMELINE, AND PRICING, I’ll need to ask you a few key questions. Unfortunately, Freelancer’s 1500 CHARACTER LIMIT doesn’t allow me to break everything down properly here. Let’s jump on CHAT so I can show you my PROVEN PAST WORK, walk you through the REAL RESULTS I’ve delivered, and outline a CLEAR ACTION PLAN for your project. You’ll immediately see why my approach is DIFFERENT and EFFECTIVE. If you’re serious about getting this done RIGHT, I’m ready to move forward. Looking forward to CONNECTING and WINNING TOGETHER. Cheers, Royal IT service

@anumarif09

Hey, ➤ I understand this is not a “basic speed optimization” project this is a high risk Core Web Vitals optimization task on a live PrestaShop 8.2.1 production environment with strict no regression requirements across checkout, tracking, GDPR compliance, and third party module behavior. The bottlenecks you listed already point very clearly toward: • JS injected LCP failures from Leo Slideshow • blocking consent scripts from iubenda • GTM duplication/tracking overhead • excessive icon/font payloads • render blocking CSS chains • inefficient above the fold asset delivery • Slick initialization JS conflicts This requires deep PrestaShop + CWV expertise, not generic “PageSpeed plugin” optimization. ⚫ QUICK QUESTIONS: ❓ Is Redis/Memcached currently enabled on the server? ❓ Are Cloudflare/CDN services active already? ❓ Do you have full staging SSH/Plesk access available? ❓ Are Lighthouse measurements currently taken with authenticated or guest sessions? I can begin immediately with a staging audit and isolate the highest impact CWV blockers first, particularly the Leo Slideshow LCP path and iubenda/GTM main thread overhead. Regards, Anum

@carlosd178

Hello, As a result of a detailed review of your project requirements, I fully understand the scope, bottlenecks, and the strict no-regression constraints. I have experience optimizing large PrestaShop stores for Core Web Vitals while preserving checkout, tracking, SEO, and third-party module compatibility. I bring deep expertise in PrestaShop 8.x, Core Web Vitals optimization, JavaScript debugging, critical CSS, GTM/GA4 optimization, iubenda Consent Mode v2 handling, Plesk/nginx tuning, and frontend performance engineering with over 10 years of experience. The main issues here are clearly the JS-injected Leo Slider LCP problem, duplicated GTM loading, render-blocking CSS, excessive icon-font payloads, and blocking iubenda execution. I can optimize the slideshow discovery/preload flow, consolidate GTM safely without breaking Ads/GA4 events, reduce font payloads through subsetting, resolve the Slick initialization error, tune cache/compression layers, and validate everything through staging-first Lighthouse/real-device testing. I have a couple of quick questions. • Is staging already synchronized with production data/modules for accurate Lighthouse testing? • Are you open to replacing some icon font usage with inline SVGs where safe to reduce payload further? I would be glad to discuss further details and can start immediately. Best regards, Carlos

@rafaels170

Hello, I carefully analyzed your Lighthouse findings and the issue is clearly a combination of JS-heavy above-the-fold rendering, duplicated tracking execution, render-blocking CSS, and inefficient asset delivery inside the Leo/iubenda ecosystem. I can optimize this safely within PrestaShop 8.2.1 child-theme architecture without touching third-party module cores or risking checkout/tracking regressions. My approach would include fixing the JS-injected LCP slider with proper preload/fetchpriority handling, consolidating GTM safely, deferring iubenda intelligently while preserving Consent Mode v2, reducing font payloads through subsetting, resolving the Slick initialization error, and tuning nginx/PHP-FPM/OPcache for faster TTFB. All work would be staged first with rollback-ready deployment, verified CWV reports, and post-launch monitoring. I’d genuinely love to work with you on pushing this store into stable 90+ territory without compromising functionality.

@ammark477

Driving real results from e-commerce performance is crucial, especially when your current scores are low. I see you're aiming for a Google PageSpeed score of 90 or above for both mobile and desktop. Let's tackle those confirmed bottlenecks effectively and ensure no regressions in functionality. My approach focuses on addressing the specific issues you've highlighted, like optimizing the Leo Slideshow for faster loading and refining how the iubenda Cookie Solution loads without disrupting the user experience. I'll also consolidate your Google Tag Managers to streamline tracking while maintaining your analytics setup. I have worked extensively with PrestaShop, especially on performance optimizations and Core Web Vitals improvements, achieving significant score increases for prior clients. For this, I plan to provide a detailed action plan within 14 days, starting in your staging environment. To kick off, would you like insights on how specific critical CSS adjustments can trim down render-blocking issues? Should I send over a brief outline of how I'd tackle this?

@codeandcommand

For PrestaShop 8.2.1, hitting 90+ on mobile is the harder target. I would start with a GTmetrix and PageSpeed Insights audit, then tackle lazy loading, JS deferral, CSS minification, and static asset caching. Most gains come from those four areas. Available now and can have it done within 48 hours. The bid is an initial estimate based on the description. Final numbers come after we walk through the scope together. Want to jump on a quick call?
