Worked on the Lollolewa/EsempiCorso repository to enhance the ticket data access layer, focusing on improving both functionality and maintainability. Developed a new method for finding tickets by ID and refactored SQL queries for greater clarity and correctness, leveraging Java and SQL within a Spring JdbcTemplate context. Introduced a custom SqlRowMapper to streamline result set mapping, which improved testability and reliability of ticket lookups. Advanced test coverage for the TicketDaoJbdc component, applying test-driven development practices. Additionally, updated documentation to support safer Git merge processes, ensuring integration flows remained robust without introducing functional changes to the codebase.
