Sean Barag is a Senior Software Engineer with 14 years of experience building resilient, developer-focused tooling and scalable systems across companies from Amazon and Hulu to Cockroach Labs, DuckDuckGo, and now Netflix. He combines deep backend expertise with full-stack UI sensibilities—having improved the Git CLI robustness and modernized CockroachDB’s admin UI build and live-reload tooling. Sean excels at developer experience and build-system engineering, often refactoring build pipelines (pnpm migration) and adding productivity-focused subcommands that speed iteration. His background in secure, mission-critical environments (Lockheed Martin and Drexel research) informs a pragmatic approach to testing, automation, and hardening. Based in Seattle, he brings a history of shipping both low-level tooling improvements (git clone behavior and remote validation) and high-impact product-facing enhancements. Colleagues rely on him to translate operational constraints into elegant, testable engineering solutions.
