FAQ
Do you provide Swagger documentation with the API?
Yes, absolutely. I configure and integrate Swagger UI automatically across all packages so you or your frontend developers can easily test and understand the API endpoints.
Can you connect your .NET Web API to frontends like React, Next.js, or Angular?
Yes. I will properly configure Cross-Origin Resource Sharing (CORS) policies and structure the JSON payloads perfectly so your frontend team can seamlessly integrate the API
What architectural patterns do you follow in your C# code?
I write clean, industry-standard enterprise code following Clean Architecture or N-Tier design patterns, utilizing Dependency Injection, Async/Await operations, and the Repository pattern for database access
Can you deploy the backend to cloud hosting servers?
Yes, I can safely set up and deploy your application and database to Microsoft Azure (App Services / Azure SQL) or a traditional Windows IIS Server.
