Team Lead for tracing agent and Go tracing libraries in APM.
Tech Lead for Go fuzzing, which supports Go developers in finding and fixing bugs and security exploits in their programs. This is the first programming language to provide this functionality in its standard toolchain, and promotes the security of the Go ecosystem. When I began this work, it was the 3rd most upvoted proposal on the Go issue tracker.
I was the lead of this ~2 year effort at all stages of development. I authored the API and CLI design, and led implementation, product planning, documentation, public communications, and launch.
I have spoken on two Go Time podcasts about fuzzing (#145, #187), authored a blog post, and contributed to the tutorial.
Tech Lead for production implementation of the module mirror, checksum database, and index (proxy.golang.org, sum.golang.org, and index.golang.org respectively), using the ecosystem and crytographic designs authored by Russ Cox and Filippo Valsorda. These are the default services used by all Go developers for secure, reliable source code downloads. Go is the first language to support downloads in this way, and this work has inspired other languages to consider using similar techniques.
I led a senior engineering team in design, development, product planning, and launch. Drove cross-team collaboration with product, legal, leadership, and the open source community. I was a primary contributor to the checksum database, which ensured consistency of Go module fetches across the entire ecosystem. This involved integrating with Trillian (the Merkle tree backing the transparency log), and implementing tiling of Trillian's data to store and serve through the frontend.
This service has an SLO of 5 9s, and I was a member of the oncall team for 2.5 years.
I traveled around the world to present the details of this project, and authored a blog post.
