Shopify UX Design & Development

Shopify UX design at Avex is grounded in structure and platform fluency. Wireframes and mobile-first layouts guide experience decisions early, allowing creative to translate cleanly into a Shopify front-end that's built for speed, accessibility, and long-term scalability.

Design and engineering work as one so brand expression never comes at the expense of speed, scalability, or conversion.

Shopify Plus Platform Migrations

Shopify migrations at Avex are treated as system transformations, not lift and shifts. We execute replatforms with a focus on data integrity, platform architecture, and operational continuity, ensuring storefronts and integrations move cleanly with preserved SEO and zero downtime. The result is a stable, scalable foundation built to support growth beyond launch.

We replatform complex environments from Magento, Adobe Commerce, BigCommerce, WooCommerce, Salesforce Commerce Cloud, and custom platforms, managing product, customer, and order data with precision.

International Expansion

Avex architects international Shopify environments by defining how localization, multi-language content, multi-currency pricing, taxes, and fulfillment operate at the system level. We design around merchant-of-record requirements, regional compliance, and market-specific rules while maintaining centralized control over data, analytics, and operations.

The result is a global Shopify architecture that supports local variation without fragmenting performance, allowing brands to scale internationally with confidence.
