Rockstar🎓
Top SchoolSophy Cao is a senior infrastructure engineer based in Stockholm with a decade of experience building and maintaining backend systems at scale, currently driving core infrastructure work at Spotify. Her background spans high-throughput, fault-tolerant systems using Erlang/Elixir, Go, Ruby and modern observability tools, with prior roles at Klarna and Derivco where she abstracted business logic and modernized legacy services. She combines strong systems-thinking from a master's in computer system science with hands-on platform work—Docker, RabbitMQ, Postgres, Ansible, Grafana and Splunk—across both greenfield services and long-lived codebases. Comfortable in both backend engineering and operational tooling, she often bridges development and CI/CD practices, a skill rooted in early Ericsson CI team experience. Fluent in Swedish tech ecosystems, she brings pragmatic reliability engineering to product-facing infrastructure challenges.
