About

Recent Past

I built performance instrumentation for Instana (and previously Tracelytics) that provides visibility into distributed application stacks. Visibility consists of key metrics and distributed tracing of requests across processes, hosts, clouds and serverless.

As requests and data are processed in distributed applications, the instrumentation times and traces the execution path of the processing across process and host boundaries.

Ruby Distributed Tracing

My focus was on Python and Ruby performance instrumentation although I also did similar work in Go and Node.js.

Open Source

I contribute to a large number of open source projects. See the Projects page or my Github profile for more details.
