Rockstar🎓
Top SchoolJon Malkin is a senior software engineer and data architect with 15+ years building large-scale data collection, identity, and privacy systems from client instrumentation to backend processing. He has led design and production of privacy-first infrastructure—authoring Yahoo’s Cookie Registry and a cost-saving large-scale Bloom filter for GDPR compliance—and now applies that experience at Apple. A founding PMC member and core contributor to Apache DataSketches, Jon has improved core Java sketching algorithms and helped expand the project across C++ and Python, demonstrating deep algorithmic and systems chops. He combines rigorous academic training (Ph.D. in Electrical Engineering) with practical product delivery, repeatedly turning complex regulatory and technical constraints into robust, efficient solutions. Colleagues rely on him for cross-functional communication and for bridging policy and engineering, and he regularly presents practical tutorials at conferences like KDD. Outside of product work he pursues creative algorithmic design and quality data practices that anticipate evolving privacy regulation.
