Worked on the opensearch-project/alerting and opensearch-project/security-analytics repositories, delivering features and fixes that improved data integrity, security, and monitoring accuracy. Developed and enhanced backend systems using Java and Kotlin, focusing on API development, system design, and robust testing practices. Addressed metadata hygiene by ensuring workflow and delegate-monitor metadata were properly cleaned up on deletion, and implemented logic to force last run context creation when workflows or monitors were re-enabled. Introduced security controls for threat intelligence feeds, including HTTP/HTTPS URL validation and API access restrictions. Maintained high reliability through comprehensive unit and integration tests, reducing regression risk and improving maintainability.
