client’s goals

We’ve provided many functionalities to, among these there are two tasks we would like to point out (point out suggested).

The first was the development of a logistic web-app that would track locations of power banks, purchases of new power banks and also identify those delivered to the storehouses. This app was also intended for accounting purposes – employees needed to assign QR (inventory) codes to every power bank and add them to the database.

The second task was to add several new functionalities to the admin panel used by Batte.RE employees, so that they could generate invoices from their database.

our solutions

The project was quite simple. We developed the first app based on a code written in React.js and Ruby and elaborated a relevant architecture. For the admin panel, we integrated a ready-made module auth0 (authorization) that connected the existing front-end with the Ruby back-end. We also implemented refactoring and fixed several bugs for both projects.
