Multi-Tenant Monitoring SaaS with Tested Tenant Isolation

This is a multi-tenant SaaS that watches TLS certificates and warns before they expire. It has tenant isolation, billing, CI (automatic checks on each change) and end-to-end tests.

We built it with our AI-assisted workflow, under written rules. We own the architecture.

Row-level security policies in PostgreSQL enforce tenant isolation inside the database. Row-level security tests and end-to-end tests run on each change.
