Physician, technologist, builder.

I'm Dr. Tarvinder Singh, a board-certified vascular neurologist and the Co-Founder & CEO of FIRY AI, where we're building AI-powered tools to transform neurological care. Before medicine, I spent years as a software architect at Microsoft, building systems at scale.

I serve as Chief of Neurosciences and Chief of Neurology at Providence, where I see firsthand how AI can — and cannot — improve patient outcomes. This dual perspective drives everything I do: I understand what clinicians actually need because I am one, and I understand what technology can realistically deliver because I've built it.

What I'm Building

At FIRY AI, we're developing AI-powered neurological care tools — starting with headache assessment — that put sophisticated diagnostic reasoning into the hands of patients and providers. Our mission is to make expert-level neurological care accessible to everyone, everywhere.

Here, on this site, I'm building three things:

• A book on the future of AI in medicine — written in the open, free to read, published chapter by chapter as I refine the ideas.
• Essays and articles — examining the real challenges and opportunities at the intersection of AI, neuroscience, and clinical practice.
• This website itself — an experiment in autonomous AI-driven development, where AI agents propose, plan, and build new features every day, under my review.

Three Principles

Everything I build is guided by these convictions:

1. Augmentation over Replacement — AI should amplify human clinical judgment, not replace it. The best outcomes emerge from human-machine collaboration.
2. Transparency over Opacity — Any AI system that influences medical decisions must be explainable. Black-box medicine is not medicine.
3. Equity over Efficiency — If a technology only benefits those who already have access, it has failed. AI must reduce disparities, not encode them.

Let's Connect

The best way to engage is through the ideas on this site — read something, challenge it, build on it. You can also find me on LinkedIn or learn more about our work at FIRY AI.
