PROFILE

Andrew Purtell

Worked on Apache HBase and Phoenix repositories, focusing on backend development, data safety, and release management using Java, Zookeeper, and XML. Delivered a feature that introduced automatic recovery snapshots before destructive table operations, reducing data loss risk and enabling rapid restoration. Addressed resource management in Apache Phoenix by fixing Zookeeper connection leaks, improving high availability and cluster reliability. Maintained release metadata accuracy for HBase by updating downloads.xml, ensuring users access correct version information. Stabilized test suites by reverting timing changes to eliminate flakiness and ensure deterministic results. Emphasized configuration management, robust testing, and integration with distributed systems throughout the development process.
