During May 2025, Nomoa focused on improving test stability and resource management in the wazuh/wazuh-indexer repository. They addressed thread leaks in S3BlobContainerRetriesTests by implementing a dedicated ScheduledExecutorService for the S3 client during tests, isolating scheduling and preventing resource contention. Nomoa updated the S3AsyncService and S3Service constructors, along with their override configuration methods, to accept and utilize an external ScheduledExecutorService, enabling more controlled test execution in both CI and local environments. Working primarily with Java, AWS SDK, and concurrency concepts, Nomoa’s targeted bug fix reduced S3-related test flakiness and improved the reliability of production workflows.
