EntityFramework/Postgres ASPNet Core project: design review and optimization -- 2

min €36 EUR / hour

We are developing a ASP.Net Core project for storing large amounts of data and offering an HTTP API. As a database we use Postgres and EntityFramework Core is used to access the database. For storing general data, we implemented a general element type holding metadata (creation timestamp etc.) and custom data (JSON serialized). Also, we implemented a simple reference mechanism where elemets can reference to other elements. Unfortunately, the system does not scale well and after adding thousands of elements, the system becomes slow. We are looking for an EntityFramework / Postgres / DotNet expert with extensive proof of expertise for reviewing and optimizing our system.

Castle Windsor - I will use this to integrate dependency injection. Do not award now as I guess there is some chances of improvement and we can work on it before start the work. I think it can solve your problem regarding slow response. Still, performance is kind of thing which we can can assure only when we will have the ready reference. I need to Get reference of Castle Windsor in your project. Then I need to Create an adopter for Castle Windsor as WindsorActivator to implement IHttpControllerActivator. The installer uses the container parameter of the Install method to Register controllers using Windsor's Fluent Registration API. The installer uses the container parameter of the Install method to Register controllers using Windsor's Fluent Registration API. After the above step we need to integrate IWindsorInstaller which uses the container parameter of the Install() method to Register dependencies using Windsor's Fluent Registration API. For work with entity framework and PostgreSQL we nee to use Npgsql which is the .NET data provider for PostgreSQL. Now, what I suggest above is from my previous experience so that I can jump on it and can give you proper information. When you think you can get back to me? I am free today for further discussion and would not mind to give you an initial consultancy. Regarding my experience, I am really open to show you my previous work. So do not hesitate if you need it from me, I am open to show my work.
