I will build secure rest API with asp dot net core, csharp and sql server


About this gig
Need a secure and reliable REST API for your web or mobile application?
I will develop a custom ASP.NET Core Web API using C#, SQL Server and Entity Framework Core, with clean, maintainable code.
What I can build:
- RESTful Web APIs and CRUD operations
- JWT authentication and role-based authorization
- SQL Server database integration
- Entity Framework Core or existing database integration
- Input validation and error handling
- Swagger/OpenAPI documentation
- Third-party API integrations
- API bug fixing, debugging and performance improvements
- Backend services for Angular, React, mobile and other frontends
My focus is not just making the API work. I understand your requirements, trace root causes, write maintainable code, and build reliable backend solutions.
I can work with a new project or an existing ASP.NET Core application, including legacy code that needs fixes or modernization.
You will receive clean source code, database integration where included, and clear communication.
Please message me before ordering with your requirements, project details, database schema, or a reference example. I will review the scope and recommend the right package or custom solution.
