Proven in production

I design and build commerce systems that handle real payments, orders, sellers and integrations.

Artovnia marketplace storefront with featured handmade products
Artovnia · multi-vendor marketplace on Medusa.js

A marketplace I designed and built from the ground up

Architecture, backend, seller panel and storefront. Independent makers run their own shops here, and a buyer pays once for a cart filled from several of them.

  1. 01

    One cart, many sellers

    The buyer pays once and the order splits into the shops that fulfil it.

  2. 02

    Commissions and payouts

    Rates and payout holds are settings, not code. Every payment is attributed to the right seller.

  3. 03

    Sync with sellers' own shops

    Sellers already on Shopify, WooCommerce, PrestaShop, Shoper or BaseLinker keep them. Stock and orders match in both places.

  4. 04

    EU marketplace rules

    DAC7, DSA and the Omnibus Directive run as separate modules that can be updated as the law changes.

  5. 05

    Robust by design

    An integration stops responding? The operation can be safely retried. The same webhook arrives twice? It does not cause a second effect. A process breaks off halfway? The state can be reconciled and restored. Critical operations leave a trail that shows what actually happened.

  6. 06

    Under the hood

    • Retries and queues
    • Idempotent operations
    • Reconciliation
    • Audit trail
    • Dead-letter handling
    • Race-condition safety

[ 01 - About ]

You talk to the person who builds your system

No account manager and no hand-offs. The person who talks to you about your business model also designs the architecture, writes the backend and the storefront, and answers when something needs to change.

We start with how you sell: who pays, who ships, who gets paid and when. The technology follows from those answers. You get the code, access to everything, and a panel where you edit content yourself.
