ETIC - E-Commerce SaaS Platform

Project Overview

ETIC is a full-featured SaaS (Software as a Service) platform that enables modern businesses to quickly create and manage their own e-commerce stores. Thanks to its multi-tenant architecture, it can run thousands of independent stores from a single codebase, with each store managing its data in isolation.
