I designed and implemented a full-stack Book Store management system using ASP.NET Core MVC, Entity Framework Core, and SQL Server. The system included database schema design with one-to-many and many-to-many relations using Fluent API, and user-friendly interfaces for managing books, orders, and customers. I applied SOLID principles, Repository Pattern, Dependency Injection, and integrated Identity for authentication and role-based authorization. The project was extended with a secured Web API layer and documented using Swagger. I achieved 2nd Place Award in the .NET Summer Training 2025 organized by OSC – Ain Shams University.
