An audiobook mobile application used by companies to educate their employees. The app makes a large collection of educational audiobooks on management, marketing, and sales available to employees. Companies can buy books and lend them to employees through the app.
MOSSUP | Recycle Plastic App for Supermarkets

To help the recycling company and the supermarkets keep track of the quantities and requests, I built a mobile application on iOS and Android using React Native that collects, parses, and displays all the information about the recycling process in the dashboard.
