Multi-Tenant E-Commerce Platform

A client operating multiple online storefronts needed a unified platform that could manage 14+ independent stores from a single codebase, each with isolated data, separate payment processing, and compliance with varying regulatory requirements. They needed fraud detection, multi-currency support, cryptocurrency payments, and automated ACH payouts — all while maintaining PCI-DSS compliance across every storefront.

We architected a multi-tenant e-commerce platform with isolated per-client sandboxes sharing a 363+ table database. The platform integrates 7+ payment gateways including cryptocurrency processing, with a dedicated fraud detection pipeline backed by its own database and failover system. We implemented geolocation-based regulatory compliance across 25 US states and 3 international jurisdictions, automated ACH/NACHA payouts, and multi-currency support. PCI-DSS compliance was maintained continuously for over 20 years across all production infrastructure.

The platform successfully operates 14+ active storefronts with isolated security boundaries. The fraud detection system catches suspicious transactions before processing. Automated ACH payouts eliminated hours of manual payment processing. The multi-tenant architecture allows new storefronts to be provisioned without infrastructure changes.
