  November 2024 – Current
  Principal Engineer Remote

  Published first version of MCP support in the agents library. We were among the first to support the Streamable HTTP transport, days after the specification was released.

  Shipped Automatic Tracing. Get detailed automatic traces and logs for your app in the Cloudflare dashboard without any changes to your Worker code, or export to any OTLP-compliant vendor. Rather than wrapping modules with outside instrumentation, we integrated tracing directly into the Workers runtime.

  Observability Team Lead Remote
  After enough demos showing how our internal Observability tooling could be improved, I helped form an internal Observability infrastructure team. We built OpenTelemetry Distributions for our internal users, making getting start with tracing as easy as possible, and keeping telemetry consistent across the org. Our team guided engineers on how to use wide events to debug their systems, built custom instrumentation, and coordinated many migrations.
