Replatforming & Migrations

01 Magento to Medusa.js

We migrate complex catalogs, custom business logic, and databases from heavy legacy Magento setups to fast, modern, and cost-effective composable architectures.

Full data mapping, historical order migration, and ERP/WMS integrations with zero downtime and a seamless customer transition.

02 Shopify to Medusa.js

Break free from Shopify’s rigid architecture. We transition your store to a composable setup for absolute control over logistics, international pricing, and performance.

Advanced API integrations, custom payment setups, and flawless SEO redirect routing to protect your search rankings.

03 Woocommerce to Medusa.js

Scale beyond WordPress database bottlenecks. We migrate your WooCommerce store to a Next.js-powered headless engine for sub-second page loads.

Database cleanup, asset migration to modern CDNs, and robust API-first checkout systems built for high-volume traffic.

What Scales With You

We build vendor-agnostic commerce systems that scale with you — handling more SKUs, markets, and traffic effortlessly.

Unified catalog & content

Structured data schemas that gracefully merge PIM/ERP products with rich editorial content. Manage complex merchandising and product storytelling in your CMS without database bottlenecks.

True global multi-market

Real localized setups with regional pricing, independent publishing flows, and AI-automated translation workflows. Built for complex cross-border logistics, not just a surface-level i18n checkbox.

Unblocked publishing velocity

Marketers and editors create shoppable landing pages, launch loyalty programs, and run seasonal campaigns without waiting for developers. Safer experimentation, faster time-to-market, and zero dev bottlenecks.

Integration-proof architecture

A decoupled, API-first setup where your Next.js frontend is separated from your backend logic. Swap or upgrade your ERP, WMS, payment systems, or CMS without ever rebuilding your storefront from scratch.
