He’s the creator of Reactive Extensions (Rx), a composable approach to asynchronous programming now widely adopted across platforms.
At Facebook (Meta), he reworked core backend systems to support reactive application development at scale. His current work focuses on making machine learning more accessible to developers—through probabilistic and differentiable programming, and by applying ML to infrastructure and tooling.
