📦 .NET 9, gRPC, PostgreSQL, Marten, Wolverine

---

🧩 A secure password management system built as two core services: an Authorization Server that handles user authentication and access control, and a Password Storage Server dedicated to manage and protect user credentials. The system is engineered to provide a reliable and highly secure solution for storing and handling sensitive login information, ensuring user data is protected with AES 256 encryption algorithm.
