Worked on the apache/flink-cdc repository to deliver password redaction for the PostgreSQL CDC connector, addressing the need for secure handling of sensitive information in logs. Implemented robust log sanitization using Java and Apache Flink, ensuring that credentials are removed from connector output without affecting runtime performance or backward compatibility. The approach focused on enhancing security and regulatory compliance by preventing credential leakage while maintaining clear audit trails. Demonstrated strong backend development skills through commit-based, traceable changes under FLINK-38685, contributing to open-source collaboration and responsible data handling practices in a high-visibility, production-grade data streaming environment.
