Rockstar🎓
Top SchoolGerard Caulfield is a pragmatic infrastructure and DevOps leader with 14 years of experience designing resilient systems, improving CI/CD pipelines, and mentoring engineering teams across startups and enterprise environments. He blends deep hands‑on skills in Linux, Docker, Kubernetes, Ruby, and databases with a track record of reducing operational friction—most recently as a Senior SRE at Workday and a cloud‑native consultant helping teams adopt Istio and better developer workflows. An active contributor to Ruby tooling, he improved test infrastructure and maintainability for the popular awesome_print library, reflecting his focus on long‑term code quality. Gerard is restless about learning new technologies, obsessed with tooling that frees developers to do higher‑value work, and once took a year to tour Japan while deliberately upskilling in modern web and container tech. Now leading his own efforts as Chief Stuff Doer, he combines practical engineering with a habit of making things measurably better for others.
