Worked on backend enhancements for the wazuh-indexer and OpenSearch repositories, focusing on storage reliability and operational resilience. Addressed snapshot reliability for closed indices by implementing a Java-based solution that fetches metadata from the remote store, ensuring successful snapshot creation and restoration even when indices are closed. In OpenSearch, removed feature flags to always register tiered storage settings, reducing configuration errors and simplifying deployment. Demonstrated expertise in Java, integration testing, and remote store management while adhering to code governance standards. The work improved data durability, streamlined storage configuration, and strengthened the reliability of backup and restore workflows in production environments.
