PROFILE
Jenny Jiang
Ying Jiang developed advanced data engineering features across the ollionorg/DataflowTemplates-fork and GoogleCloudPlatform/DataflowTemplates repositories, focusing on Spanner integration and schema management. She implemented Avro format import and export for Spanner NOT ENFORCED Foreign Keys in the GoogleSQL dialect, extending the ForeignKey model and updating schema parsing logic to improve data interchange and pipeline reliability. In parallel, she enabled property graph creation on Spanner views, updating DDL-to-Avro schema conversion and ensuring correct dependency ordering. Using Java, Avro, and Spanner, Ying delivered well-tested, maintainable solutions that expanded analytics capabilities and improved the robustness of data modeling workflows within these platforms.
