Jason Zaman is a systems architect and full-stack developer with 15 years of experience building secure, scalable systems and apps used by over 8 million users. Based in San Francisco, he blends deep systems and security expertise—seen in sustained contributions to upstream SELinux, OpenZFS, and OpenRC—with practical experience in Android, embedded firmware, and complex build systems. As a Gentoo SELinux lead and TensorFlow SIG-Build maintainer, he navigates both low-level kernel-adjacent work and higher-level developer tooling. Jason organizes and speaks regularly at FOSS and Android events (DroidConSG, GDG SG), reflecting his role as a community leader and evangelist. Colleagues describe him as a big-picture thinker who dives into analytical, performance- and security-focused fixes that often touch build processes and assembly-level concerns. His open-source track record shows a knack for subtle, high-impact improvements—from fixing integer overflows and executable-stack issues in ZFS to optimizing SELinux userland behavior—underscoring a rare combination of systems depth and developer-facing influence.
