Fashion & Jewerly E-commerce Websites | Senior Shopify Developer | CRO

Most Shopify stores do not have a traffic problem. They have a conversion, performance, and reliability problem. I help Shopify and Shopify Plus brands scale with conversion-focused builds, Checkout Extensibility, Shopify Functions, and integrations that stay reliable. If any of this feels familiar, I can help: • You’re spending on ads but conversion is stuck • The theme is slow and every change feels risky • Checkout limitations are costing you revenue • Apps and integrations are messy and break often • You need someone senior who can own the roadmap end-to-end How I work: • Diagnose what’s blocking revenue (CRO + performance + tech debt) • Ship high-impact fixes fast (PDP, cart, checkout, collection UX) • Stabilise the foundations (integrations, data syncs, tracking, SEO hygiene) • Keep momentum with a clear roadmap and reliable delivery What I build: • Shopify Plus builds and replatforms (DTC and B2B) • Checkout Extensibility + Shopify Functions • Custom apps, integrations, and data pipelines (ERP, 3PL, CRM, analytics) • Headless (Hydrogen/Remix) when it makes business sense • Performance + technical SEO tied to revenue metrics Why clients hire me: • 10+ years on Shopify • 500+ builds shipped • Hands-on from architecture to QA and launch If you want a technical partner who can own the roadmap and ship reliably, message me and tell me what you are trying to improve (conversion, checkout, speed, or integrations).
