Readme

Implement an ExchangeRateProvider for Czech National Bank. Find data source on their web - part of the task is to find the source of the exchange rate data and a way how to extract it from there.

It is up to you to decide which technology (from .NET family) or package to use. Any code design changes/decisions to the provided skeleton are also completely up to you.

Goal is to implement a fully functional provider based on real world public data source of the assigned bank.

Please write the code like you would if you needed this to run on production environment and had to take care of it long-term.

Decisions

• I'm using vertical slice architecture, grouping things by feature.
• I don't follow one class, one file rule.
• I don't create layers I don't currently need. For example, I don't have the service above repository when the service would be just passing through things. For example, the CnbIntegrationService could be split into repository and service. But YAGNI and when we will need it, be it for the need for some business logic or for testing, we can split it.
