John McClean is an architect at AOL, where he leads the Advertising Demand Side Forecasting team, which builds and runs a system that processes billions of RTB, impression, and viewability records in real time to generate price volume curves and other forecasts for advertising campaigns in milliseconds. John is also the lead developer for AOL open source projects cyclops-react and Microserver. Extracted from AOL’s forecasting system, these projects allow AOL to rapidly deploy new features that work at scale by guiding Java developers along the path of functional, reactive microservices. John has 16 years of software development experience and has been with AOL for 11 years.
