This was a project I did with two other students for the Crimson Code Hackathon 2019. The application would succesfully scan a food items barcode and report to the user if any selected allergins were within the food product. We found a large (200,000+) free to use data set of food items with barcode numbers which we stored on an Azure database to allow the applicatoin to work. We were all new to Kotlin and phone applications so had a bit of a learning curve and thus did not complete as much as we were hoping but to get the basic functioning within the Hackathon made us happy. This project is not functioning anymore due to the database being taken down so I don't have video showing off the application unfortunately, but you can still view the Github.
I worked on designing the functionality of the application with the other two students. After we had a plan I mainly worked on the barcode scanner which I was able to find a free to use API to implement this. I also helped out with the UI after completing the scanner.
