I am building a web-based application in .NET and need help completing the data-management layer. The system must store and manipulate two primary datasets—user information and transaction records—while enforcing role-based access for Admin and standard User accounts. Here is what I need from you: • Design or refine the database schema so both datasets are structured for scalability and easy reporting. • Build the API and back-end logic in ASP.NET (Core 6 or later preferred) with Entity Framework for data access. • Implement CRUD operations, search, basic filtering, and pagination for each data type. • Add role checks so Admins can see, create, update, and delete everything, while Users have read/write rights only to their own records. • Integrate simple front-end views (Razor Pages or Blazor Server is fine) that let me test all endpoints end-to-end. Acceptance criteria 1. All endpoints return 200/201 and the correct JSON when hit from Postman. 2. Admin and User roles are enforced through an attribute-based authorization policy. 3. A short README explains how to run a local build and apply migrations with dotnet ef. If you have production experience with ASP.NET Core, Entity Framework, and SQL Server (or PostgreSQL), I’m ready to get started right away.

A scalable data layer with strict role-based access is the backbone of any secure web application. With over 12 years of production experience in full-stack .NET development, ASP.NET Core, and SQL Server architecture, I can quickly and cleanly build your complete backend and test views. Here is exactly how I will deliver your requirements: Schema & EF Core: I will design a normalized, scalable SQL Server database for Users and Transactions using EF Core Code-First migrations, ensuring optimized structures for future reporting and rapid querying. API & Core Logic: I will build robust RESTful endpoints (using ASP.NET Core 8 or 6, per your preference) handling all CRUD operations, complete with integrated search, filtering, and efficient server-side pagination. Role-Based Security: I will implement ASP.NET Core Identity. Using attribute-based authorization ([Authorize(Roles="Admin")]) and EF Core global query filters, I will guarantee Admins have global control while standard Users are strictly isolated to reading and writing their own transaction records. Front-End Integration: I will build a lightweight Blazor Server or Razor Pages UI to serve as a functional test harness, allowing you to easily verify all data flows and role checks end-to-end.
