CartScale

High-performance e-commerce infrastructure

Overview

CartScale is a custom e-commerce platform built for a fast-growing DTC brand that outgrew Shopify. The platform was designed to handle massive traffic spikes during product drops while providing a seamless shopping experience across all devices.

We built a headless commerce architecture that gives the marketing team full control over the frontend experience while maintaining robust backend systems for inventory, payments, and fulfillment.
