Worked on the k-wall/kroxylicious repository to deliver real-time connection activity metrics and observability improvements for backend systems. Developed gauges that track active connections between clients, proxies, and servers, enabling immediate load monitoring and deployment validation. Instrumented core proxy logic in Java and updated integration tests and documentation to support these new metrics. Enhanced logging by updating Log4j configuration to print all key-value pairs, improving debugging and monitoring capabilities. Maintained codebase hygiene by removing deprecated directories and ensuring clear, traceable commits. Focused on backend development, metrics, and monitoring, with work primarily in Java, YAML, and logging configuration for maintainability.
