Hi there!
I've read your project description. You are looking for a Web API developer who can help you build a solution that can accept CSV files to import data, transform that data into business entities and provide endpoints to let users get the data.
Fortunately, I've worked on a project like this before.
I am a full stack .NET developer. I've worked with multi-tier architecture, SOLID code, Restful APIs, third-party integrations, etc. I am well versed in developing web solutions in ASP.NET Core, MVC, Web API, SQL Server, Entity Framework, EF Core and Dapper.
I believe I can definitely help you out with this.
If any of this sounds interesting, please reply to this and we can arrange to discuss your requirements in detail.
Best regards,
Divyansh Bhatia,
