During June 2025, contributed to the micrometer-metrics/micrometer repository by implementing a new feature that enables LongTaskTimer to report a MAX duration metric in its measurements. This addition improves observability for latency-sensitive tasks by allowing users to monitor maximum task durations, supporting outlier detection and SLA validation. The work involved updating the measure() method and enhancing test coverage in SimpleMeterRegistryTest to ensure the new metric was accurately reported. Leveraged Java and the Micrometer metrics framework, applying unit testing practices with JUnit and following test-driven development principles to deliver a focused, business-impacting improvement in performance monitoring capabilities.
