Hi there!
I've read you requirements. It seems you are looking for a .NET developer who can help you build a web application that will work on desktop, tablets and mobile devices. You also want to use SQL Server along with ASP.NET for this project.
I believe I can definitely help you out.
I am a full stack developer. I have worked on similar projects using similar technologies.
I am well versed in developing web solutions in ASP.NET, ASP.NET Core, ASP.NET MVC, Web API, Azure, TypeScript, SQL Server, Entity Framework, EF Core and Dapper.
If any of this sounds interesting, please reply to this and we can arrange to discuss your requirements in detail.
Best regards,
Divyansh Bhatia
