I will add jwt auth and role based permissions to your dotnet app

Is your app missing proper login security, or does it have a basic auth system that needs to be production-ready?

I specialize in adding secure, scalable authentication and authorization to existing .NET (ASP.NET Core) and React applications. This includes:

• JWT authentication with refresh token rotation
• Role-based and permission-based access control (not just "admin vs user" granular permissions per feature/action)
• Secure password hashing and validation
• Global exception handling and proper CORS setup
• Clean integration into your existing codebase (I work with what you have, not a rewrite)

I built this exact system for a multi-tenant ERP application clean layered architecture, permission-based authorization at the endpoint level. I bring that same production-grade approach to your project.
