Rockstar🎓
Top SchoolColby Gutierrez-kraybill is a seasoned technology leader and current Director of Technology/CTO at the Scratch Foundation, with over a decade of experience designing and operating high-throughput web platforms that supported hundreds of millions of annual users. He combines hands-on SRE/DevOps and backend engineering expertise—spanning Node, Python, Ruby, Java, C/C++, and Go—with strategic platform architecture and deployment improvements (notably for the scratch-www client, Dockerization, Sentry, New Relic, and Fastly tuning). His earlier career includes low-level embedded and scientific software for radio astronomy (UC Berkeley, SRI) where he led control systems and observatory infrastructure, giving him rare depth across hardware, telemetry, and large-scale web services. A co-author of the log4r library and active open-source contributor, Colby is interested in the intersection of computability and abstract mathematics and the pedagogy of higher math—bringing both practical systems mastery and a research-minded curiosity to educational technology.
