WordPress Speed Optimization Expert with 5+ years of experience. ⚡ I specialize in WordPress performance optimization, Core Web Vitals, PageSpeed Insights, and GTMetrix optimization, delivering real, measurable speed improvements. 🚀 WordPress speed optimization expert at your service. My name is Serge. For the last 5 years, I’ve been focusing exclusively on WordPress speed optimization and WordPress performance optimization. With over 300 WordPress websites optimized, I’ve gained hands-on expertise that I use to improve WordPress website speed, Core Web Vitals, and PageSpeed Insights scores. ⚡ A well-optimized website helps with WordPress SEO and, most importantly, improves user experience, which leads to lower bounce rates and higher conversions. No business can afford a slow website anymore, and no WordPress SEO strategy is complete without proper WordPress speed optimization. 🧩 A well-planned WordPress speed optimization and performance optimization process consists of the following steps: ⚪ WordPress performance audit using PageSpeed Insights and GTMetrix optimization benchmarks. This helps identify weak points in Core Web Vitals (FCP, LCP, CLS, TTFB). ⚪ Website cloning and optimization environment setup: safe testing environment, server comparison, WordPress caching strategy, and CDN setup (Cloudflare, Bunny.net, or similar). ⚪ WordPress caching configuration: choosing and configuring the right caching solution - WP Rocket, LSCache, or server-side Varnish cache, resulting in improved TTFB and overall WordPress performance. ⚪ Asset cleanup and WordPress optimization: image optimization for WordPress, font optimization, lazy loading, database cleanup, and removal of unused assets. ⚪ WordPress performance configuration: core WordPress tuning and Elementor speed optimization, Divi speed optimization, or other page builder performance optimization. ⚪ Testing phase: Nothing goes live until everything is verified. WordPress speed improvements must never break website functionality. Attention to detail and real performance optimization (not cosmetic tweaks) is key here. ⚪ Implementation and reporting: The outcome is improved Core Web Vitals, higher PageSpeed Insights scores, and better GTMetrix benchmarks, while the website functions exactly the same — only faster. 🛠 Tools & plugins I use for WordPress speed optimization: There is no single tool or plugin that fits all WordPress websites; otherwise, WordPress performance optimization would be trivial. WordPress caching: WP Rocket, LSCache, Varnish, W3 Total Cache Asset optimization: Asset CleanUp Pro or similar Image optimization WordPress: Imagify, Hummingbird, EWWW CDN services: Cloudflare, Bunny.net, Amazon S3 This is not a complete list; tools are selected based on what works best for each WordPress website. 🎯 What kind of WordPress speed improvement can you expect? It depends on what WordPress optimization has already been done. * Previously optimized WordPress websites: ~2× performance improvement * Non-optimized WordPress websites: 4–9× speed improvement 📈 PageSpeed Insights scores typically range from 70 (heavy WordPress websites) up to 95+. A precise WordPress performance estimate is provided after the initial speed audit. No guesswork — you know the performance targets before the work begins. 🔧 Do you work with WordPress page builders? Yes. While builders add overhead, Elementor speed optimization and Divi speed optimization can significantly improve WordPress performance. I work with Elementor, Divi, and other WordPress builders. 📍 Do you work with Shopify or other platforms? No. I intentionally focus exclusively on WordPress speed optimization and WordPress performance optimization. I currently do not offer Shopify speed optimization or Webflow speed optimization services. 📌 What other services do you provide? While I don’t build WordPress websites from scratch, I’m proficient in most WordPress-related tasks, including: 🔹 No-downtime WordPress migrations 🔹 Critical error (500x) recovery 🔹 WordPress backup & maintenance services 🔹 Malware removal and security fixes 🔹 Other WordPress optimizations and troubleshooting 🏆 Why choose me for your WordPress speed optimization project? ✓ WordPress speed optimization is my core specialization ✓ I deliver real, measurable WordPress performance improvements ✓ Tool-agnostic approach — I implement what works best for your WordPress website You’re in experienced, reliable hands when trusting me with WordPress performance optimization. 📋 How does the optimization process start? Every project starts with a technical WordPress performance audit (Core Web Vitals, TTFB, caching, assets). Based on real data, I define clear performance targets and an optimization strategy before any changes are applied. 📩 Message me and let’s make your WordPress website fast, stable, and conversion-ready.

Senior WordPress & WooCommerce Developer with 10+ years of experience building fast, stable, and maintainable websites for ecommerce brands, SaaS companies, startups, agencies, and established businesses. My core focus is custom WordPress development, WooCommerce customization, performance optimization, and high-quality frontend implementation. I help clients improve slow, outdated, or difficult-to-maintain websites by identifying the real technical causes behind poor Core Web Vitals, plugin bloat, theme limitations, excessive scripts, slow templates, weak caching setup, and frontend performance issues.

Hi, I'm Alex - a Senior WordPress/WooCommerce Developer specializing in peptide and research-compound eCommerce stores. I build, rebuild, and optimize peptide stores end-to-end: design, WooCommerce setup, high-risk payment gateway integration, and — as part of every build — WordPress Speed Optimization to hit 98–100% PageSpeed Insights scores and pass Core Web Vitals. Slow WordPress sites lose visitors, hurt SEO, and cost you money — and peptide stores are especially vulnerable, with heavy catalogs, compliance widgets, COA/lab-result pages, and high-risk gateway scripts all stacking up.

I build and optimize custom WordPress sites and WooCommerce stores that load fast and actually convert. My specialty is the part most developers skip. On the conversion side: upsell funnels, 1-click upsells, opt-in flows, and post-purchase pages. On the performance side: serious speed optimization that takes slow WordPress sites and WooCommerce stores into the green zone on Core Web Vitals. Both matter. A fast site that doesn't convert is wasted traffic. A high-converting site that loads in 6 seconds bleeds users before they ever see the offer. I work on both. ✦ WHAT I BUILD FOR WOOCOMMERCE STORES ✦ → Upsell and cross-sell funnels (in-cart, post-purchase, 1-click upsells) → Opt-in funnels for lead magnets, free trials, and email list growth → Abandoned cart and checkout recovery flows → Custom checkout pages built to convert (not the default Woo checkout) → Subscription systems, product bundling, and dynamic pricing → Conversion-focused product pages, landing pages, and sales pages ✦ SPEED & PERFORMANCE OPTIMIZATION ✦ → WordPress and WooCommerce speed optimization with before and after PageSpeed scores → Core Web Vitals fixes (LCP, CLS, INP) for Google rankings and UX → Database cleanup, query optimization, and caching strategy → Image optimization, lazy loading, and asset minification → Plugin audits and removing performance-killing bloat → Hosting recommendations and server-side improvements ✦ CUSTOM WORDPRESS DEVELOPMENT ✦ → Custom WordPress builds from Figma, pixel-perfect, fully responsive → Custom plugin development for business logic that doesn't fit off-the-shelf → Custom Post Types and ACF for scalable content architecture → Elementor Pro builds your team can actually edit after launch → Migrations from Shopify, Wix, Squarespace, or outdated WordPress → Security hardening, backups, and ongoing support ✦ HOW I THINK ABOUT YOUR PROJECT ✦ Most developers ask what you want built. I ask why. Where do your buyers come from? Where do they drop off? How fast does the site load on mobile? What's your AOV today and what should it be? Those answers shape the build. Otherwise you get a pretty store that's slow and doesn't move revenue. ✦ WHO I WORK BEST WITH ✦ → WooCommerce store owners doing $10K+ per month who want to scale AOV and conversions → Course creators, info product sellers, and DTC brands building real funnels → Marketing agencies that need a senior WordPress and WooCommerce partner for client work → Founders with a slow WordPress site that's hurting rankings, conversions, and ad performance ✦ STACK ✦ WordPress, WooCommerce, Elementor Pro, Figma, ACF, Custom Post Types, custom plugin development, WP Rocket, RankMath SEO, GravityForms, GA4, Google Tag Manager, Zapier, GoHighLevel 📍 Based in Prague, Czech Republic ✅ Fluent English ⚡ Fast replies, honest timelines Send me your WooCommerce store URL or your WordPress site. I'll come back with specific speed and conversion ideas, no charge. Last update: June 16, 2026
