Desenvolvimento de uma aplicação móvel voltada para a venda de queijos Canastra autenticados

The popularization of the internet and mobile devices has profoundly trans- formed the way products and services are marketed, driving the growth of electronic commerce (e-commerce). However, the agribusiness sector, especially small-scale producers and family farming, still faces challenges in effectively adopting these tech- nologies. In this context, this work presents the development of a mobile application aimed at the commercialization of authenticated Canastra cheeses, with the goal of connecting producers and consumers and promoting the value of artisanal production. The proposed solution was implemented using React Native for mobile app develop- ment, Node.js for the back-end, and a relational PostgreSQL database for data sto- rage. The system also incorporates a product authentication mechanism based on unique identifiers, reinforcing the reliability of transactions. The main contribution of this project is the creation of a comprehensive digital platform that integrates featu- res such as producer, product, and customer registration, purchase tracking, inventory management, sales history, shopping cart, and order automation. The application was developed with a focus on usability, meeting the needs of producers who gain an ac- cessible tool for managing and selling their products, as well as consumers, who can make purchases in a practical and intuitive way. By facilitating the sale and distribution process of Canastra cheeses, the application contributes to the technological inclu- sion of family farming in the digital marketplace, promoting innovation in the sector and expanding the reach of local producers.
