Private AWS API development

Job ID: 34727515

Budget: $250 – $750 USD

I need to be able to allow listed providers to use my API to transfer data between each other in a sort of sharing manner for details to check if a profile is active or cancelled and to check for duplicates.

There are basic details to be shared of certain users between these listed providers but I'm look to have it for only certain individuals.

The api must be well documented so that the providers are able to allow their developers to understand and integrate it easily on their systems.
I was thinking of an easy way to view this information like a dashboard for them to view and request these details but this needs to be done on the most cost effective way on aws and must be safe as it's personal information.

This is a small project for for an AWS developer but I need assistance for this project and willing to pay based on project completion only after ensuring the solution is in working condition I would also like to have a proper view of the usage as an admin and be able to send an invoice based on usage to the providers for using the API.

I really want to be able to have a very cost effective solution so the fees don't go too high on Aws so the developer must fully understand how to enable the structure to reduce overheads.

The information will be details that come from the providers example name surname date of user signup and general information but not huge data so the API is just to be able to provide a view of details between these providers the reason I'm saying this is because I want to ensure that this API does not cost an arm and a leg I'm looking at the most efficient and cost effective price from a developer to do this please don't bid low amounts just to discuss further and then tell me that it's going to be a 100 times more expensive than your bid after discussing.

I need to build this as soon as possible and test so a decent bid with the intention of concluding this job is important to me.
