I’m overhauling a growing startup’s ASP.NET Core codebase and I need another set of expert hands. The immediate focus is to simplify and clean up the API layer, with special attention to the database-interaction code. We are on SQL Server, hosted in Azure, and wired into Azure DevOps for CI/CD, so solid experience across that stack is essential. Beyond the back-end work, you should feel comfortable dipping into the HTML and lightweight UI touches that surface in our Razor pages. The first milestone is to rebuild the authentication portion of the API; once that is stable we will iterate through the remaining endpoints. To make sure we are a good fit, I’ll start you on a contained trial task. Let me know: • Your hourly rate • The number of hours you can commi...

I need a clean, well-structured ASP.NET REST service that processes static infrastructure data stored in a SQL database. The service must expose endpoints to create, read, update and delete the records, returning JSON throughout. Key points • Technology stack: ASP.NET (Core preferred) with Entity Framework (Code First or Database First—use what lets you move fastest) and Microsoft SQL Server. • Data model: a small set of tables representing our infrastructure items; I will supply the exact fields once we start, but plan for typical ID, name, location and status columns. • Endpoints: /items (GET list, POST create), /items/{id} (GET, PUT, DELETE) plus any helper routes you feel are useful. • Processing rules: basic validation (unique names, non-null locat...

I’m building a production-ready web application on ASP.NET Core and need a seasoned C# engineer to accelerate the backend and UI layers. The project already has a clean architectural outline; what I’m missing is expert-level implementation that ties everything together smoothly. Core scope • Secure user authentication and role-based access (ASP.NET Core Identity). • Robust data-processing routines that read, transform, and persist large datasets via Entity Framework Core and SQL Server. • Interactive reporting and dashboard views with concise visualisations; or any comparable library is fine as long as the end result is responsive and exports cleanly to PDF/Excel. Your tasks will include wiring up the authentication flow, designing efficient EF Core mode...

I need a small, self-contained module written in ASP.NET that lets me turn specific product attribute values on or off. The immediate focus is on the Color and Size attributes, so the code should let an admin mark any Color or Size value as “enabled” or “disabled” and have that flag respected wherever the catalog is rendered. My site is already running on ASP.NET, so the deliverable must blend smoothly with an existing code-base and database schema. I expect: • A clean UI element that plugs into the current admin area to manage the toggle state. • All business logic wrapped in a service layer so I can reuse it in other screens or an API later. • Database integration that records the enabled/disabled status without altering unrelated tables. &b...
