Enterprise Authentication and Authorization Flow
Identity-aware application flow across primary React frontend delivery, Web API contracts, identity-provider callbacks, logout, refresh and security boundaries.
Supported enterprise identity and access-management changes, including migration from TrustBuilder to Microsoft Entra ID.
The work covered primary React frontend delivery, frontend/backend responsibility boundaries, Web API contracts, callback handling, logout behavior, token refresh flows, generated OpenAPI clients, mock-service testing and secure coordination between application teams and platform teams.
The architectural goal was to make the authentication path understandable, testable and maintainable while keeping security responsibilities explicit for development, testing and operations.
