Enterprise WooCommerce Store With Integrations

We are looking for a highly skilled WordPress / WooCommerce developer to build and optimize a large-scale e-commerce platform handling over 100,000 products.
The products will be imported and synchronized from multiple supplier XML feeds (3–5), each with a different structure and pricing model.

The store will operate in Greece, connected with local banks, courier APIs, and ERP systems for real-time automation.

ERP system (Prosvasis GO, Soft1, or similar) for invoices & stock sync.
