Kshitij Tandon contributed to the opensearch-project/index-management and wazuh/wazuh-indexer repositories by building and refining backend aggregation features, plugin enhancements, and governance processes. He implemented ScriptedAvg-based aggregation logic in Java, improving distributed average calculations and test coverage. In the dashboards plugin, he expanded transform API validation to support wildcard index patterns and addressed security vulnerabilities in CI/CD workflows using TypeScript and GitHub Actions. Kshitij also led maintainers’ governance updates, ensuring robust code review and repository management. His work demonstrated depth in backend development, aggregation frameworks, and DevOps, resulting in more reliable, secure, and maintainable OpenSearch components.

September 2025 monthly summary for opensearch-project/index-management: Delivered a refactor of AvgAggregation to ScriptedAvg and extended test coverage with value_count aggregation. This work improves accuracy, scalability, and maintainability of distributed average computations across shards.

December 2024 focused on strengthening repository governance and code ownership for two OpenSearch components. Implemented thorough maintainers and codeowners updates across both dashboards plugin and core index-management repos, coupled with controlled rollback to correct governance drift. The changes are process-oriented (no customer-facing feature releases) but deliver safer, auditable code review and deployment workflows.
