Yeah, sure. So, as part of my first company wherein basically I was working on creating REST APIs from scratch, it was a microservices based architecture. So therein, it was a pharmacy based project. So I created multiple APIs dealing with a specific feature. So for instance, I created an API that only deals with insurance plans information. Though that API I created, so it has multiple layered architecture. So for instance, it had a controller layer which will interact with the client. Then it had a validation layer. There are certain business logics that needs to be performed. So there was a validation layer, then a business logic layer to perform business logic based on the data that we are fetching from the database. And then the database layer to fetch the response or to submit the response or to save the changes that the user has submitted from screen. So that is the API that I created. That we used to deploy using Dockers. So that API we deployed in Docker containers, then it was in Kubernetes cluster. So it gives automatic scaling and availability in case if there is a heavy traffic and if one instance is crashing, then the traffic will move on to the upcoming or to other instances which are still working. So it won't impact for the client to serve any request.
