WordPress Speed Optimization Expert | PageSpeed 95+ | Core Web Vitals

Is your WordPress or Shopify website slow, hurting your SEO rankings and losing potential customers? I specialize in fixing slow WordPress and Shopify websites at the root level — not just applying plugins or surface-level tweaks. Most performance issues come from bad themes, heavy plugins, unoptimized code, and server bottlenecks. I solve these problems through deep performance engineering, Core Web Vitals optimization, and code-level improvements to deliver fast, stable, and conversion-focused websites. What I Deliver : ➡ 90+ Google PageSpeed Insights (Mobile & Desktop in most cases) ➡ Core Web Vitals pass (LCP, CLS, INP improvement) ➡ Reduce page load time to ~2 seconds or less ➡ Faster real-user experience (not just lab scores) ➡ Improved SEO performance & conversion rate ➡ Stable, safe optimization (no design or feature breakage) What I Fix in Your WordPress Website : ➡ Fix slow WordPress websites caused by plugins/themes ➡ Full WordPress speed optimization (end-to-end audit + fix) ➡ Core Web Vitals optimization (LCP, CLS, INP, FCP) ➡ PageSpeed Insights optimization (mobile + desktop) ➡ GTmetrix & Lighthouse performance optimization ➡ Reduce page load time & improve site speed ➡ Remove render-blocking CSS & JavaScript ➡ Optimize CSS, JS, fonts & third-party scripts ➡ Image optimization (WebP, lazy load, compression) ➡ Database cleanup & performance tuning ➡ Server response time (TTFB optimization) ➡ Advanced caching setup (WP Rocket, LiteSpeed, server-level) ➡ CDN setup & Cloudflare optimization ➡ WooCommerce speed optimization (cart, checkout, product pages) My Optimization Approach : I don’t just “speed up websites” — I fix performance problems permanently. ➡ Full performance audit (PageSpeed Insights, GTmetrix, Lighthouse) ➡ Identify bottlenecks (code, server, assets, plugins) ➡ Create optimization strategy based on real data ➡ Apply safe, staged improvements (no downtime, no breakage) ➡ Validate Core Web Vitals in real-world conditions ➡ Re-test and optimize until stable performance is achieved Tools I Use — Google PageSpeed Insights • GTmetrix • Lighthouse • WebPageTest • Google Search Console • Pingdom • Cloudflare • Google Analytics 4 (GA4) Platforms I Work With — Shopify • Shopify Plus • WordPress • WooCommerce • Elementor • Elementor Pro Why Clients Hire Me : ➡ Focus on real performance improvements, not just scores ➡ Deep understanding of WordPress architecture & Core Web Vitals ➡ Safe optimization with zero design disruption ➡ Proven experience with complex, high-traffic websites ➡ Fast communication and reliable delivery ➡ Long-term performance improvement approach 🎯 My Goal • Faster websites • Better SEO rankings • More conversions • Seamless user experience Share your website URL and I’ll quickly analyze the speed issues and explain what’s affecting performance — you can take it from there.
