What is covered
SaaS product development is a distinct discipline from general web development. It requires deliberate decisions about tenant isolation: row-level isolation, which separates tenant data using a tenant identifier column within shared PostgreSQL tables, or schema-level isolation, which gives each tenant a dedicated database schema. It requires subscription logic integrated with platforms such as Stripe or Chargebee, identity layers built on OAuth 2.0 and JWT (JSON Web Token), SSO (Single Sign-On) configuration, and RBAC (Role-Based Access Control) that scales as each customer's team grows. These architectural decisions must be resolved before application code is written, not retrofitted later.
