Rockstar🎓
Top SchoolDavid Morrison is a founder and research scientist with 12 years of experience building and optimizing distributed systems, currently leading open-source R&D in scheduling and autoscaling from Sacramento. He previously scaled infrastructure at Airbnb and authored Clusterman at Yelp, bringing deep hands-on expertise in cluster autoscaling for Mesos and Kubernetes. An active open-source contributor, his work on Kubernetes autoscaler and Moto improved AWS integration, reliability, and performance of cloud autoscaling and EC2/Spot Fleet testing. Trained as a computer scientist with a PhD from UIUC and a BS in Mathematics from Harvey Mudd, he combines rigorous research instincts with production-grade engineering. Outside engineering he pursues photography and playful side projects—currently an accidentally emergent role-playing game—reflecting a creative approach to problem solving.
