Earlier README

I'm a senior software engineer in Milwaukee, and I work on browser performance and observability. I write TypeScript and Go. I'm looking for my next role in browser engineering or web performance, Denver preferred.

Recent

My Faro exporter fix in the OpenTelemetry Collector contrib repo merged October 16, 2026 and shipped in v0.164.0. The Faro translator fuzz tests and fix that returns the meta encoding error have merged too. I now have four merged pull requests in collector-contrib.
More Go work is open: mdatagen README markers in the Collector, Alloy CORS headers for the Faro receiver and goroutine stack traces in support bundles, a k6 navigation check, and list_alerts truncation in the Prometheus MCP server. My Collector fix to preserve the connection's remote address is approved.
Grafana Faro: one merged pull request and six open pull requests in faro-web-sdk, covering hard page load navigations (#2359), custom web vitals labels (#2361), custom text masking for session replay (#2362), and the move of tracing setup onto the OpenTelemetry trace SDK (#2358, #2363, #2364 for the SDK 3.0 upgrade).
OpenTelemetry browser SIG: I'm nominated as an approver on #549, still open. I have 8 merged pull requests in opentelemetry-browser, and I've reviewed 75 pull requests across nine OpenTelemetry repos.
Safari: the browser SDK wouldn't start on Safari 17 because of URL.parse. #447 fixed it, and I wrote up why below.
Web performance specs: I opened a non-normative section on computing INP for the W3C Event Timing spec (#175) and moved the CLS explanation in WICG layout-instability to session windows (#131). Both are open. Google's web-vitals took three of my fixes.
Client-side semantic conventions v0.1.0-dev, the first dev release of the browser and mobile registry, came out October 27, 2026. It has #33 in it, which moved enduser.id and enduser.pseudo.id over from core.
I now have four merged pull requests in OpenTelemetry JS. This week, #7262 fixed B3 trace ID length validation, and #7253 documented that API 1.10.0 needs SDK 3.x.
OpenTelemetry JS #7153 removed the pagehide listener from the trace and log SDKs, and shipped in 3.0.0.
OpenTelemetry demo #3966 replaced the Python recommendation service with Java on Spring Boot 4 and merged October 13, 2026. On November 3 #4232 gave its catalog calls a deadline. The companion Helm chart change is still open.
