Worked on enhancing data-loading reliability and test coverage for the apache/doris repository, focusing on Table-Valued Function (TVF) features. Developed and integrated Groovy-based automated test suites to validate TVF data loading against abnormal scenarios, such as incorrect data types and formatting issues, improving early detection of edge-case failures. Addressed CSV parsing reliability by fixing test cases to correctly handle enclose and escape characters, reducing flaky outcomes and increasing test accuracy. Leveraged skills in Groovy, SQL, and ETL processes to expand regression coverage and automate testing within the CI pipeline, contributing to more stable and reliable production data workflows.
