Rockstar🎓
Top SchoolBenjamin Schwartz is an engineering manager and privacy-minded systems engineer with 17 years of experience building secure networking and mobile infrastructure. He co-created Outline (a widely used self-managed VPN) and authored Intra, a DNS-over-HTTPS Android app that reached over 1.8M active installs, and helped design the "HTTPS" DNS record used in modern resolver deployments. At Google/Jigsaw and now Meta he led DNS and mobile network-stack efforts, implementing DNS-over-TLS and DoH support across products and contributing to IETF standards work as a WG chair. His background as a PhD-trained biophysicist and former medical ML researcher gives him a rare blend of rigorous research discipline and pragmatic engineering. He frequently combines low-level C/C++ DNS work with Android client development and DevOps improvements, optimizing both performance and security in high-throughput network paths. Based in New York, he is passionate about open standards, user privacy, and tooling that scales from phones to public nameservers.
