I fix the things most SEO freelancers can't touch. My background is split between development (Python, PHP, HTML, CSS) and SEO, which means I don't just identify technical problems, I solve them in the code. Where I deliver the most value: diagnosing traffic drops and ranking changes through Search Console data, resolving Core Web Vitals issues (CLS, LCP, FID), building and optimizing WordPress sites on clean code without page builder bloat, and connecting the dots between what Google wants technically and what users need on the page. I've worked across WordPress, Shopify, and Wix builds. I handle keyword research, competitor analysis, on-page optimization, schema markup, and site speed from both the SEO and the development side. When something breaks, I find it. When something's slow, I fix it. If you need someone who understands why a page isn't ranking and can actually implement the fix without handing it off to a separate developer, that's what I do.

I help businesses fix slow, underperforming WordPress and Shopify websites and turn speed into measurable revenue. Most sites I take on are losing sales to slow load times, failed Core Web Vitals, and years of plugin and theme bloat. I strip that back and rebuild it fast, clean, and built to convert. ➜ Recent results: » Shopify store: custom development + speed optimization → $49K additional monthly revenue (42% increase) » Corporate WordPress site: migrated to headless Next.js → 67% faster load, 38% more leads » SaaS platform: performance optimization → now handles 25K+ concurrent users smoothly » Top clients have seen 35–50% revenue increases within 90 days of launch or optimization 100+ web development and optimization projects delivered. 100% Job Success on Upwork. Based in London (UK), working across UK, EU, US and global timezones. ➜ WHAT I DO ⚡ WordPress & WooCommerce Speed Optimization & Development » Core Web Vitals and PageSpeed / page speed optimization (LCP, CLS, INP) » Plugin and theme cleanup, database optimization, caching setup » Custom theme and plugin development (ACF, Gutenberg blocks, Elementor) » WooCommerce store development and performance optimization » WordPress migration with full SEO and ranking preservation » Vercel and Cloudflare CDN deployment ⚡ Shopify & Ecommerce Speed Optimization & Development » Shopify store speed and Core Web Vitals optimization » Liquid theme development and custom templating » Ecommerce conversion rate optimization (CRO) audits and fixes » Custom Shopify app development and Shopify Plus customizations » Checkout extensibility, Shopify Functions, metafields » Klaviyo / Omnisend email and GA4 conversion tracking ⚡ Headless Architecture (WordPress & Shopify) » Headless WordPress with Next.js, React and WPGraphQL » Headless Shopify storefronts (Hydrogen and custom Next.js front-ends) » Decoupled / API-first CMS integration (Contentful, Sanity, Prismic) » WordPress-to-headless migration with SEO and rankings preserved » Vercel and Cloudflare edge deployment for sub-second load times This is where my best results come from. The headless Next.js migration above delivered 67% faster load and 38% more leads. If you're hitting the ceiling of what a standard WordPress or Shopify theme can do, headless is the upgrade. ⚡Also available: Webflow development (Client-First builds, Figma to Webflow CMS, Finsweet attributes). ➜ GETTING STARTED Send me your website URL and I'll record a short free audit showing exactly what's slowing your site down and where you're losing sales or speed.
