The app is designed for babysitters and parents. Users are divided into two categories: babysitters, who provide services, and parents who need a sitter for their child. The server is fully Dockerized. Deployment is split into 2 stages: Actual build of the app & Running tests & Build of Docker images and pushing them to ECR as well as triggering ECS. ECS represents a part of the cluster that is responsible for running Task Definitions. If Task Definitions are failed, the service will repeat the process. Task Definition defines what operations should be done to a container. The containers’ settings are stored here, as well as a link to an image inside ECR. To sum up, the whole deployment process looks like this: Pushing changes to ECR; Starting cluster’s services (ECS); Executing a Task Definition of each service.

This app is intended for buying and selling international stocks and shares. The application consists of screens of registration (registration flow: verification of phone number, email, PIN input), login, displays the rates and each stock/share info page, personal profile etc. Stocks update in real time. During the work process the API integration, animation implementation, application architecture building, application internationalization, module decomposition were realized. The app collects users IDs and documents needed to complete a purchase through the inbuilt APIs. The app has admin side and user side, allows administrating purchases and processing them via admin. All the data is stored in an external server.
