What you get with this Offer
I will build, fix, or improve an ASP.NET Core Web API endpoint for your application.
This offer is suitable if you need help with a .NET backend issue, a new API endpoint, database integration, request/response models, validation, or fixing an existing API that is not working correctly.
What I can help with:
• Create a new ASP.NET Core Web API endpoint
• Fix an existing API issue
• Connect the API to SQL Server
• Add request and response models
• Add validation and error handling
• Work with Entity Framework, Dapper, or SQL queries
• Test the endpoint using Postman
• Provide a clear summary of what was changed
This offer includes one simple API endpoint or one backend fix.
For larger requirements involving multiple endpoints, authentication, deployment, React frontend changes, or complex database work, please contact me first so I can review the scope and provide a suitable quote.
I have over 11 years of experience working with C#, ASP.NET Core, SQL Server, React, Azure, REST APIs, and business applications.
