Contributed to the Duansg/hertzbeat repository by developing and enhancing Prometheus-based observability features over a two-month period. Built a Prometheus Metrics Online Parser in Java, enabling real-time metrics ingestion and supporting multi-source querying across endpoints like VictoriaMetrics and Greptime. Refactored parsing logic into common utilities, removed deprecated code, and added comprehensive unit tests to improve maintainability and reliability. Integrated Prometheus pushgateway support and automated monitor creation for incoming metrics, streamlining data ingestion workflows. Addressed a URI construction bug in PromqlQueryExecutor, ensuring robust query execution. Leveraged skills in backend development, data parsing, and system integration using Java, Go, and TypeScript.
