Overview

At Inveterate, I built a Shopify application combining membership, loyalty, and third-party integrations into a unified platform, enabling merchants to manage customer engagement and external services through a single system.

The Problem

Loyalty programs required separate tools or custom builds

Third-party integrations were complex and inconsistent

No unified way to manage customer engagement + integrations

High technical barrier for merchants to adopt advanced features

The Solution

Membership and loyalty system

Integration hub for third-party APIs

Merchant dashboard for full control

Real-time event processing via webhooks

Architecture

Core Components

Membership & loyalty engine (tiers, rewards, points)Integration hub for third-party Shopify ecosystem APIsMerchant admin dashboardCustomer-facing components for enrollment and rewards

Technical Design

Backend: Node.js services with REST + GraphQL APIs

Event-driven ingestion of Shopify store events via Amazon EventBridge

Queue-based processing for async workflows

Scalable AWS infrastructure
