Custom e-commerce store migrated from Shopify
Vzorky Parfémov
The project was built as a replacement for the original Shopify setup, which was too costly and limiting for a smaller online store. The goal was to create a custom e-commerce system with lower monthly costs, lower transaction fees, and more control over orders, shipping, invoices, and content.
E-commerce architecture
Shopify migration
Frontend development
Context
The original solution worked, but operationally and financially it no longer made sense.
Challenge
The store originally ran on Shopify, where monthly costs included the platform fee, a Packeta plugin, and higher transaction fees. The Packeta shipping process was also unnecessarily manual and limited by the external plugin.
Goal
The goal was to build a custom e-commerce solution on Medusa.js that reduces monthly costs, lowers transaction fees, enables a more flexible shipping integration, and gives more control over orders, invoices, emails, products, and content.

What's included
A complete e-commerce system from backend to fulfillment.
The project included Shopify migration, Medusa backend setup, storefront, products, blog, payments, shipping, emails, invoices, SEO, deployment, and custom admin extensions for practical daily operation.
Medusa backend and product catalog
I set up the Medusa.js backend, products, variants, inventory, shipping settings, and core e-commerce processes needed to run the store.
Storefront and customer interface
The storefront includes a landing page, product catalog, product detail, cart, user accounts, blog, FAQ, and responsive interface.
Stripe payments and lower transaction fees
Stripe was integrated to replace the original Shopify payments and reduce transaction costs from 3.5% + EUR 0.25 to 1.5% + EUR 0.25.
Custom Packeta integration
The original manual export-and-plugin process was replaced with an API integration. Shipping a package became a flow of opening an order, submitting it to Packeta, and printing the label.
Invoices, emails, and workflows
The system includes custom invoice generation, internal and customer transactional emails, and workflow logic for order processes.
Custom infrastructure and deployment
The solution runs on a custom VPS through Coolify, with separate Medusa server, worker, storefront, PostgreSQL database, Redis, and AWS service integrations.
Decisions
What mattered most in the project
This project was not only about redesigning the store. The key was to reduce costs, remove manual steps, gain more control over operations, and keep the system flexible for future expansion.
01
Migration away from the Shopify ecosystem
Moving to a custom solution removed monthly platform and plugin fees and enabled more control over how orders, payments, shipping, and content work.
02
Simplifying Packeta fulfillment
The original process required selecting the order, exporting CSV, downloading the file, logging into Packeta, importing it, confirming it, and printing the label. The new API-based solution reduced the flow to a few clicks directly from the order.
03
Custom Medusa admin extensions
The admin was extended with practical tools for transactional emails, invoice generation, and Packeta workflow so daily operations could be handled in one place.
04
SEO migration and content preservation
Blog articles were migrated from Shopify and the new solution was prepared with sitemap, metadata, JSON-LD/schema.org markup, and Search Console.
05
Operational infrastructure
Deployment had to account not only for the storefront, but also for the Medusa server, worker, database, Redis, storage layer, emails, and stable operation on owned infrastructure.
