ECOMMERCE FACTORY
// the case study
One brain, many faces. A subscription SaaS that stamps out a premium store per merchant.
// the brief
Multi-tenant e-commerce SaaS: sign a merchant up, stamp out a proven premium storefront — CRWN is the die. NestJS and PostgreSQL underneath, with tenant isolation enforced by row-level security at the database layer rather than in application code.
// the wins
- Tenant isolation by row-level security at the database layer — not in application code
- One proven storefront (CRWN) stamped out per merchant, subscription-priced
- NestJS + PostgreSQL core with Next.js, Angular, and Astro faces
- One brain, many faces — shared engine, per-merchant identity
01 // the thesis
Most small stores fail on plumbing, not products — payments, catalog, orders, hosting. The factory ships the plumbing already proven: every merchant gets a CRWN-grade store on day one and rents the machine instead of rebuilding it.
02 // the isolation
Multi-tenancy is where SaaS goes to leak. Here the wall is row-level security at the database layer: even buggy application code cannot read across tenants, because Postgres itself refuses. Isolation is a property of the data, not a promise of the code.
03 // the die
CRWN is the master mold — one storefront polished until it sells, then stamped per merchant with their identity on top. One brain, many faces.
