Rockstar🎓
Top SchoolChris Harris is a Sr. Staff AI Engineer with nine years of experience applying machine learning and AI to networking, security, healthcare chatbots, and product personalization. He blends a strong theoretical foundation—a Ph.D. in Mathematics—with hands-on big-data engineering in Java/Scala and Python, having built and deployed ML and contextual bandit systems at Expedia, Shopify, and Babylon. At Infoblox he focuses on AI for network/security problems, while his open-source contributions to CoreDNS and Kubernetes perf-tests show deep involvement in DNS performance, TLS integration, and Kubernetes deployments. Comfortable moving models from research to production, he also brings low-level systems sensibility from significant work on Spark, Kafka, and Cassandra, plus experience optimizing large-scale DNS behavior that few ML engineers have.
