PROFILE

Paolo Morandini

Worked on enhancing test coverage for the google/dwh-migration-tools repository, focusing on the reliability of Snowflake JDBC SQL generation. Developed a new test method in Java that automatically compares SQL statements produced by the connector with expected results defined in a YAML file. This approach enabled automated regression testing, ensuring that SQL output remains consistent and correct during migrations. Leveraged backend development skills and SQL expertise to strengthen the project’s quality assurance processes. The work laid a foundation for future test-driven development and reduced migration risks, with no major bugs reported during the period and a clear emphasis on robust testing practices.
