I work on browser performance and OpenTelemetry.
- OpenTelemetry demo #3966: replaced the Python recommendation service with Java on Spring Boot 4. Merged October 13, 2026, and the docs update merged that day too. The companion Helm chart change is still open, waiting for a demo release.
- OpenTelemetry Helm charts: merged fixes for conflicting event presets and the operator metrics Helm test. The demo's Prometheus memory change is still open.
- OpenTelemetry JS #7153: removed the
pagehidelistener from the trace and log SDKs. - OpenTelemetry browser #467: fixed sibling counting in CSS
nth-childselectors.
- react-inp-blame: connects slow browser interactions to React renders and handlers when it can identify them.
- otel-js-upgrade: reviewable migration diffs for OpenTelemetry JavaScript. It applies supported SDK 2.12 changes and previews SDK 3 migrations.
- otel-zoneless-context: browser context manager without zone.js, with a bundler plugin that restores context across the native
awaitcalls it rewrites.
