Ruth is a member of the Core Site Reliability Engineering team at Pinterest, where she experiences interesting outages, and works on systems and internal tools to help Pinterest stay up, including the flamegraph profiler tool, Python monorepo, and containerization movement. She likes anything at scale -- be it software at Pinterest, or visiting factories for fun. Ruth likes to pin desserts to bake, and DIY projects to laser cut and sew at her local makerspace. Previous speaking engagements include SREcon17Americas, SaltConf17, and PyCon Canada.
