Ariel David Leza developed and integrated a donations module for the VoucherDesenvSenacHub/together repository, focusing on backend development and database modeling using PHP. He designed a Donation model with fields for value, anonymity, and date, establishing associations to users and NGOs, and implemented a user-based search to retrieve donation records. Ariel enhanced the user interface by enabling dynamic table rendering of donation data, updating controllers and views for accurate data presentation. He also refactored authentication and session management logic, improving error handling and streamlining session variable assignments. The work emphasized maintainability and laid groundwork for future testing and refactoring efforts.
