This is the application that I developed during Smart India Hackathon in 2019. This basically solves the problems of many companies regarding the packaging of their goods.
It takes the physical and chemical properties of the packaging materials like plastics, glass, cardboard, aluminum, etc and its cost according to its area. It then applies a greedy algorithm to optimize the packaging area as well as material costs.
I along with my team developed it using Python as backend, using bootstrap/HTML and CSS for frontend. For the database, we used Firebase.
