I will build or fix asp dotnet core rest apis with sql server


About this gig
Need help building an ASP.NET Core API or fixing a backend issue?
I will develop a clearly scoped API feature or troubleshoot an existing backend using C#, ASP.NET Core, Entity Framework Core, and SQL Server.
I can help with:
- REST API endpoints and CRUD operations
- Entity Framework Core and LINQ
- SQL Server database integration
- Request validation and error handling
- API documentation and testing
- Troubleshooting existing business workflows
My experience includes backend development and ERP manufacturing workflows involving production orders, inventory management, material issuance, and inspections.
You'll receive the agreed source-code changes, verification of the affected functionality, and setup instructions as specified in your package.
Please contact me before ordering with your .NET version, requirements, relevant code, and expected behaviour.
Large ERP systems, complex migrations, production database changes, and deployment require separate assessment. Please remove passwords, connection strings, and other secrets before sharing code.
