Experience
Kwalito
I founded and built this company and app from scratch. The mobile application verified the composition of food products simply by scanning their barcode. It aimed at users with allergies or food intolerance, vegetarians, vegans, pregnant women, and users who wanted to eat healthily and read ingredient lists before buying a product. This app was developed for Android and iOS and was an alumnus of Numa Sprint, Season 7, and Koudetat The Family. Kwalito was also integrated with Smart Food Paris, the first food tech incubator of Paris&Co.
