Shopify Plus Developer | CRO, Migrations & AI Integrations

I help Shopify and Shopify Plus brands sell more, not just look better: conversion-focused redesigns backed by real A/B tests, checkout upgrades, deadline-driven migrations, and AI features wired into live store data. Top Rated Plus, 100% Job Success, 6+ years, 100+ stores built and rebuilt across fashion, beauty, health, automotive and food. Clients usually come to me when: - The store looks good but doesn't convert - Shopify deprecated something (Scripts to Functions, checkout.liquid) and there is a hard deadline - Too many apps slow everything down - They want AI in the store (smart recommendations, support automation, AI search) connected to real products and orders, not a demo What I do best: - Conversion optimization: UX/UI changes validated with A/B testing (Intelligems), not guesswork - Shopify Plus: Checkout Extensibility, Functions, migrations off deprecated features - Custom development: clean Liquid, custom sections, Figma to Shopify, no hacks - AI integrations and automation for e-commerce stores Recent results (2026): - I run the ongoing CRO program for a European home goods group with three Shopify storefronts (NL/DE/FR). Recent A/B wins: +16% mobile conversion rate on a cart free-shipping test, and a size-guidance feature that won with 84-85% probability (both measured in Intelligems) - Migrated all landing pages off a paid page builder to native theme sections with zero downtime, removing the app dependency and its scripts - Compressed a flagship product gallery from 44MB to 3.6MB (WebP) with no visible quality loss - Built an AI agent that monitors every live A/B test across the three storefronts daily and alerts the team in Slack - Connected a Shopify store to a major UK retailer's marketplace (Mirakl): catalog integration plus live stock sync On our first call I'll walk you through a report on your store: real numbers, where revenue is leaking, what to fix first. If you want your Shopify store to sell more, let's talk. Open to a store review, test task, or short discovery call.
