A mobile application that helps users to maintain their mental health with the help of AI algorithms. Users fill in the information about their state, and the application analyzes it and provides helpful advice and exercises to improve users’ mental well-being. The work on the project is organized following the SCRUM framework. The main goals were to redesign the existing application, add new features, and improve user experience. The project was transferred from monolithic to microservice architecture to ensure easier scaling and maintenance. There was a need to create a UI library with cross-platform components to reuse among all the services and an analytics service to track users’ actions and analyze statistics. Both packages are published using the NPM register.

A marketplace helps to match two categories of users: those who need particular work to be done and those who have particular talents to do the work. Users can choose among several opportunities or offers, find a perfect match, and be sure about the safety of payments.
