    Multi-Tenant Commerce Platform

    Shared infrastructure, isolated data

    EntrepreneurBuilder

    What it is

    A commerce backend that serves multiple brands from shared infrastructure while maintaining complete data isolation.

    Why it exists

    Running separate infrastructure per tenant doesn't scale economically or operationally.

    Constraints

    • •Row-level security, not application-level filtering
    • •Tenant switching must be impossible even with bugs
    • •Performance can't degrade with tenant count

    What was hard

    • •Making RLS policies composable and testable
    • •Handling cross-tenant admin operations securely

    What changed my mind

    • →Moved from tenant ID in path to JWT claims. Simpler, more secure.
