Rockstar🎓
Top SchoolJames Sanderson is a pragmatic software engineer with 14 years’ experience, currently a Member of Technical Staff at Tailscale in London, focused on secure, server-side systems and DevOps. He blends deep Unix (Linux & FreeBSD) expertise with strong security and internationalisation instincts, and contributes regularly to well-known open-source projects such as Bundler, RubyGems, toml-rs and Tailscale itself. His work often targets reliability and testability—improving test suites, error handling and edge-case parsing—to raise long-term maintainability across ecosystems. A Bristol Computer Science graduate, he pairs hands-on backend development with a knack for spotting subtle protocol and tooling gotchas, such as lockfile merge-conflict handling and EOF parsing edge cases.
