Over a three-month period, AJ Leong contributed to backend and API development across the wazuh-indexer and opensearch-api-specification repositories. He delivered robust Search Relevance API specifications and endpoints using YAML and OpenAPI, enabling analytics and experimentation workflows in OpenSearch. In wazuh-indexer, AJ improved test reliability by refining Java-based test logic for metric aggregation and addressed edge cases in geo-spatial data handling, adding safeguards for geopoint sorting when fields are null or empty. His work emphasized precise fault isolation, comprehensive schema definitions, and strengthened test coverage, resulting in more reliable CI pipelines and reduced risk of regressions for downstream consumers.

Concise monthly summary for 2025-08 focusing on wazuh-indexer geopoint sorting robustness and related bug fix; delivered code changes and tests to improve reliability when geopoint fields are null or empty.

Month: 2025-05 — Key features delivered: Stabilized the Metric Aggregator test suite in wazuh-indexer by correcting test logic so range queries apply only to non-keyword fields and removing an outdated annotation. Major bugs fixed: MetricAggregatorTests.testStarTreeDocValues logic bug, improving test accuracy and preventing false failures. Overall impact: Increased CI reliability, reduced flaky tests, and faster feedback on indexer changes, enabling safer releases. Technologies/skills demonstrated: Java-based test engineering, JUnit/test annotations cleanup, regression testing, and precise, commit-level fault isolation.
