Summary
🤩
RockstarNate Mcmaster is a seasoned software engineer with 12 years of experience building and operating large-scale infrastructure and developer tooling, currently on Anthropic’s infrastructure team in Seattle. He has led teams at AWS as a principal engineer owning internal networking services that handled billions of requests per day and previously contributed core build, runtime, and tooling work for ASP.NET Core at Microsoft. Nate combines deep back-end and DevOps expertise—CI/CD automation, build systems, packaging, and cloud-native deployments—with active open-source stewardship, notably across high-profile dotnet repos like aspnetcore, EF Core, and tooling such as dotnet watch and DotNetCorePlugins. He excels at simplifying complex build and release workflows, improving testability, and modernizing cross-platform support, often implementing pragmatic fixes that improve robustness and developer productivity. Known for mentoring and unblocking teams, he still writes production code regularly and publishes practical OSS improvements that many .NET projects rely on. An interesting detail: his GitHub contributions span both low-level build system refactors and user-facing tooling, reflecting an unusual blend of automation-first thinking and hands-on developer experience optimization.
