Worked on the apache/paimon repository to enhance data integrity and schema management for large-scale data pipelines. Addressed ByteBuffer string conversion issues in Iceberg manifests by ensuring exact content length handling and UTF-8 encoding, eliminating padding errors and potential data corruption. Expanded test coverage to include special characters and multi-byte encodings, verifying manifest reliability. Later, implemented robust schema evolution support across Iceberg and Flink CDC connectors, enabling accurate retrieval of the latest schema ID and comprehensive handling of nested data types such as ROW, ARRAY, MAP, and MULTISET. Leveraged Java, backend development, and data engineering skills to improve cross-system data consistency.

Jun 1, 2025June 2025: Delivered robust schema management across Iceberg and Flink Paimon connectors in apache/paimon. Implemented retrieval of the latest schema ID from the Iceberg schema cache to ensure correct versioning, and extended the Flink CDC connector for Paimon to fully support nested schema evolution, including ROW, ARRAY, MAP, and MULTISET, with tests. These changes improve data correctness, reduce runtime schema drift, and enhance pipeline stability across cross-system data flows.
