Jeremy Mickelson is a Senior Staff Software Engineer and experienced technology leader with 14 years of building scalable systems from startup to acquisition and running large engineering organizations. He has led architecture and delivery of factory and manufacturing execution software at Tesla, scaled core product and revenue-driving systems as CTO at AllyDVM, and now drives recommendation systems at Meta. Fluent across languages and stacks—Go, Ruby, Java, JavaScript, and C—he rapidly masters new domains and technologies, having taught himself CockroachDB, Kubernetes and other tools to ship production systems. Notably he designed immutable manufacturing data streams and globally interconnected factory deployments to enable safe cross-factory material and data movement. A pragmatic open-source contributor in the Ruby ecosystem, he’s equally comfortable writing low-level integrations and shaping high-level system architecture.
