John Mckay is a Principal Data Scientist with 8+ years of delivering high-impact AI, statistical, and optimization systems across logistics, e-commerce, and defense. He has a track record of translating research into production—driving multimillion-dollar outcomes such as a $58M/year pricing model, a $52M/year route optimizer, and a patented vision-language theft-detection system. Comfortable from bandits and hierarchical Bayesian models to transformer-based ER and vision-language architectures, he pairs deep math (PhD in Electrical Engineering) with pragmatic engineering and deployment experience. At Amazon he led national transportation ML efforts and contributed production-grade DKIM/Ed25519 features and tests to the rspamd open-source project, highlighting a security-conscious backend engineering streak. Now at Microsoft he focuses on agentic AI solutions for financial firms, bringing both domain breadth and a history of solving limited-data, safety-sensitive problems. Colleagues value him for combining principled methods with a bias for productionization and measurable business impact.
