E-commerce
Elysium
for Elysium Technologies
A multi-store commerce backend and admin panel for a US e-commerce startup.
The problem
Elysium needed one backend for many businesses, each with its own stores, staff, and roles, before it could put a storefront in front of anyone.
What we built
A Fastify and TypeScript API on PostgreSQL and Neo4j, with Auth0 sign-in and email invitations, role-based access, and models for businesses, stores, products and variants, orders, payments, and shipments. A React admin panel for products, orders, stores, and roles. Swagger docs and a GitHub Actions deploy to AWS EC2.
What happened
Built alongside the client's own engineers and handed over with automated deploys and documented endpoints.
