Pietro Marinari enhanced the ticket management data access layer in the Lollolewa/EsempiCorso repository, focusing on improving both functionality and maintainability. He introduced a find-by-ID method and refactored SQL queries for clarity, leveraging Java and Spring’s JdbcTemplate to streamline database interactions. By implementing a custom SqlRowMapper, he improved result set mapping and testability, supporting more reliable ticket lookups. Pietro also advanced test coverage for the TicketDaoJdbc component, applying test-driven development practices. Additionally, he updated documentation to facilitate safer Git merge processes. His work demonstrated depth in backend development, database interaction, and codebase maintainability within a short timeframe.
