Transportation Project

I worked on a Python back-end RESTful API with a PostgreSQL database and React for the front end. I led the project, but it is still not in production.

The idea of the product is to help Macedonia have a better delivery system and track where a packet is. The product can be used for buying food from restaurants and delivering packages, and the drivers can see the map where they need to pick up the package and what the fastest route is for delivery.
