Sar Haidar is a Platform Engineer at MIT Open Learning and creator of SyntheticAuth.ai, where he writes about identity and AI with philosophical depth and skeptical humor.

His path to identity wasn't typical. Having spent his life immersed in different cultures through education and travel, he learned early that identity isn't just a technical problem. That perspective shapes his work—less focused on protocols, more on the human questions underneath.

At MIT, he works on the systems that make learning accessible at scale. Through SyntheticAuth, he explores the philosophical underpinnings of the identity systems we take for granted. He's also an active open-source contributor, believing that the infrastructure of trust should be visible and collaborative.
