Worked on the kaltura/server repository to enhance the reliability and observability of backend workflows, focusing on the mergeNewlyCreatedDuplicatedUsers process. Introduced structured, newline-safe logging and adopted Unix epoch timestamps for metrics, enabling more effective PromQL-based monitoring and alerting. Standardized metric naming and ensured consistent success and failure signals, supporting robust dashboards and faster incident response. Additionally, addressed a critical bug in PHP’s APCu cache retrieval by correcting syntax in kApcWrapper.php, restoring stable cache-dependent operations. Demonstrated expertise in backend development, caching, and log management, with a focus on operational robustness and data-driven monitoring across complex server-side systems.
