With a bachelor's degree in physics and a secret past as an Operational Excellence Engineer at Amazon.com, Evan Miller has made a career attempting to thread the needle between mathematical modeling and practical engineering challenges. "Evan's Awesome A/B Tools", a set of JavaScript calculators he made in grad school, are now used throughout the A/B testing industry, helping practitioners plan their experiments with the appropriate amount of statistical power. His blog is known in the hackersphere for bringing clarity to statistical problems and a touch of humor to endless Internet debates about programming languages. For nearly a decade, Evan made his way as an independent Mac developer, making easy-to-use apps for data analysis. Most recently, he has combined his knowledge of statistics with his engineering expertise in the unique role of a Statistics Engineer, where he helps Eppo build out a world-class, warehouse-native experimentation platform for companies that appreciate the perils of trying to build one themselves.
