This practice aimed to develop a management system for sports centers, in order to improve efficiency and user experience. By using technologies such as Dart and Supabase, we sought to offer an intuitive and customizable platform that allows sports centers to organize their information, manage their users, control access to facilities and track the physical progress of users. In addition, a microservices-based architecture was implemented to ensure the scalability and flexibility of the system. This project was carried out in collaboration with Komercia, where two student interns worked using an agile methodology such as Scrum to fulfill assigned tasks and achieve established objectives.
