Specialty-Paper E-Commerce Platform

## problem

A specialty-paper retailer needed to sell thousands of products online with industry-specific attributes (brand, color, texture, basis weight, eco-friendliness) that a generic store can't express, plus B2B buying behavior like sample orders and quotations.

## what I built

Developed on EC-CUBE 4.3 (Symfony / PHP), deeply customizing the core with a paper-industry product model, a mini-sample ordering flow, a B2B quotation (estimate) module, headless-CMS content integration, and admin workflows for bulk CSV import and PDF receipt/delivery-note generation. Integrated credit-card and B2B invoice payment gateways.

## highlights

• »30+ custom domain entities and 75+ database migrations
• »B2B quotation module on top of the standard cart flow
• »Headless-CMS integration for editorial content
• »Multiple payment gateways (card + B2B invoice)
