The architecture of the new version of the Greenwheels web-application. The frontend of the 'user account' was rebuilt with React, and on the backend node.js was used with connection to a few different APIs (.NET, Java). Created a private npm-repository with reusable React npm modules. Some of the modules were used in the old fronting in 'book a car' for Greenwheels and 'Audi shared fleet'.Target: Define technologies and frontend architecture for the new Greenwheels… Show more The architecture of the new version of the Greenwheels web-application.

Some of the modules were used in the old fronting in 'book a car' for Greenwheels and 'Audi shared fleet'.Target: Define technologies and frontend architecture for the new Greenwheels web-app.Actions: I selected React as the main library for UI. The site was split into two independent parts: car rental and user profile. We (the team) started with the user profile. I managed to define the architecture and we created a completely new feel and look for the first part of the application. During the development, we also made our own sharable components and stored it in the private package management server.Result: All new user profiles for Greenwheels, with settings, ride history, and payments setup; set of components to use for the rest of applications.Stack:JavaScript, React, Docker, Node.js, npm modules, SSR Show less
