- Establish and evolve secure development patterns for NestJS, including guards, interceptors, middleware, decorators, validation, error handling, logging, configuration, and dependency management
- An identity provider, including authorization, token, user-info, discovery, key-set, and logout endpoints
- A relying party, including client registration, redirect handling, authorization-code flows, token exchange, session establishment, and logout
- Help define and enforce authorization models using RBAC and, where appropriate, claims-based or policy-based access control
