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.
