The main goal of this project was to allow multiple dealers to have an inventory of their cars. Request data based on the VIN number and upload all the info. The app takes that data and reposts the car selling info on multiple pages. Worked as a project architect with a team of 2 junior developers. The project was built on time for Android & iOS using React Native. The users can keep the inventory always updated with access to information about their vehicles at any time and place.
