Worked on backend reliability and correctness improvements across Apache DolphinScheduler and Apache Gravitino repositories, focusing on Python and Java. Addressed a critical issue in DolphinScheduler by implementing an exponential backoff mechanism for task dispatch retries, capping delays at 60 seconds to align with documented behavior and improve scheduling predictability. In Gravitino, resolved runtime errors in the Python client by replacing class-based storage handler mappings with actual handler instances, ensuring proper method invocation and stability across s3a, oss, and abs backends. Demonstrated backend development and bug-fixing skills, contributing to more reliable task scheduling and robust Python-based storage interactions.
