Bruno Bat delivered OpenTelemetry enablement across the open-telemetry/opentelemetry.io and quarkusio/quarkus-quickstarts repositories, focusing on documentation, configuration, and test environment stability. He authored a new Quarkus OpenTelemetry zero-code Java documentation page, providing clear Maven and Gradle onboarding guidance, and updated Java docs to highlight Quarkus as a zero-code instrumentation option. In quarkusio/quarkus-quickstarts, he aligned OpenTelemetry integration with Quarkus 3.19, enabling default metrics and logs, and improved test reliability by disabling the Grafana LGTM dev service. His work, primarily in Markdown and Properties, enhanced developer onboarding and consistency without introducing critical defects during the release period.
