FAQ
What do you need from me to start?
A short description of the feature, expected endpoints, database details if any, and access to your existing codebase or API spec. If you do not have a spec, I can help define it from your requirements.
Do you work with existing projects or only new APIs?
Both. I can build new NET Core APIs from scratch or enhance and fix existing codebases, including refactoring for better structure and maintainability.
Do you include database integration?
Yes. I can integrate SQL Server or PostgreSQL using Entity Framework Core or optimized SQL queries depending on your project needs.
Will you add authentication and authorization?
Yes. I can implement JWT authentication and role based authorization, or integrate with your existing auth setup.
Do you provide Swagger documentation?
Yes. I update Swagger for endpoints I develop so your API remains easy to test and maintain.
Can you deploy to Azure?
I can support Azure deployment guidance and troubleshooting. If you want CI CD pipelines or Azure specific setup, that can be added as an extra service.
What if my requirements change after we start?
Minor adjustments are fine. If the scope changes significantly, I will suggest a fair update to the package or a custom offer before proceeding.
