Top SchoolPatrick Mcfadin is a distributed systems expert with 14+ years building always-on, globally distributed data platforms and a career focus on making large-scale databases reliable under real-world operational pressure. As an Apache Cassandra committer and PMC member, he shapes storage engine evolution, replication and consistency strategies while improving developer and operator experiences for some of the largest Cassandra deployments. He has led developer relations and technical strategy roles at DataStax and IBM, advising customers on multi-region availability, database modernization, and preparing data for GenAI and vector-aware real-time systems. Patrick co-authored Managing Cloud-Native Data on Kubernetes and continues to bridge cloud-native stateful patterns with production realities. He combines hands-on engineering—evidenced by contributions to reference projects like KillrWeather integrating Cassandra with Spark, Kafka, and Akka—with advisory and product strategy work for startups and enterprises. Based in Windsor, CA, he prizes clarity, observability, and operability, aiming to make critical systems “forgettable” because they simply run.
