Artur B.

Senior Shopify and WooCommerce developer who fixes difficult e-commerce problems, integrations, migrations, and performance issues without risky changes to your live store. I’m Top Rated Plus with a 100% Job Success Score, $700K+ earned, 290+ Upwork jobs, and more than 10,500 hours worked through the platform. Clients hire me when their ecommerce store needs more than a generic theme edit or another plugin. I diagnose the underlying problem, explain the safest solution in plain English, and implement it carefully. I can help you with: • Shopify theme, Liquid, JavaScript, HTML, and CSS fixes • Shopify app, API, Klaviyo, inventory, and fulfillment integrations • WooCommerce checkout, payment, shipping, AJAX, and plugin issues • WordPress and WooCommerce staging, hosting, and production deployments • WooCommerce, WordPress, and legacy-platform migrations to Shopify • Store speed, Core Web Vitals, and technical performance improvements • Product, variant, collection, navigation, and store-operations problems • Ongoing Shopify and WooCommerce development support How I work: • I investigate before changing production code. • I use staging, backups, and controlled deployment whenever possible. • I communicate clearly about scope, risks, timing, and tradeoffs. • I test the completed work across the affected store flows. • I can handle focused one-time fixes or become your long-term ecommerce developer. A good fit usually starts with one of these situations: • Something broke and the previous developer cannot identify why. • An app or integration does not behave correctly with your store’s workflow. • You need to migrate without losing products, customers, orders, SEO value, or functionality. • Your Shopify or WooCommerce store has become slow, fragile, or difficult to maintain. • You need an experienced developer who can take ownership instead of waiting for step-by-step instructions. Send me your store URL, a description of the problem, the desired outcome, and any relevant deadline. I’ll tell you what I would investigate first and whether the work is best handled as a focused fix, an audit, or a staged project.
