Summary
👤
Senior🎓
Top SchoolBryan Johnson is a Staff Machine Learning Engineer with nine years of experience building production-grade ML systems that bridge statistical learning and large-scale engineering. He has delivered high-impact solutions across finance, advertising, and HR—reducing ETL times from days to hours, detecting accounting and fraud anomalies in production, and powering a terabyte-scale identity graph that drove significant ad revenue. At Workday he led agentic AI and evaluation frameworks for autonomous workflows and shipped generative tools that accelerated developer productivity; he now continues that trajectory at Guidewire. Bryan’s background in mathematics underpins a careful, numerics-first approach to model development and distributed computation. He combines hands-on systems optimization (multi-threaded C# apps, Spark/Hive pipelines, real-time streaming stats) with a deep interest in numerical computing, making him adept at turning complex data problems into reliable, auditable systems.
