Summary
🤩
Rockstar🎓
Top SchoolIan Gudger is a software engineer with 11 years of experience building robust networking and infrastructure systems, currently based in the San Francisco Bay Area. He has a strong track record at Google and startups, contributing to core networking projects like gVisor, netstack, and the Go standard library—work that includes allocation-free DNS parsing, Unix domain socket improvements, and implementing SO_TIMESTAMP and ping sockets. At companies from Stairwell to AppLovin and CoreWeave he has combined backend systems design, SRE responsibilities, and tooling for deployment, testing, and data extraction across complex environments. He is skilled in Go, C/C++, and low-level networking, and has repeatedly fixed subtle concurrency and error-handling bugs in foundational code. Notably, he migrated large codebases to hermetic builds and created fake services and integration test frameworks to enable reliable production deployments.
