Why I write

My Books

I write these books to help engineers become better at building AI systems. The most useful lessons I've learned came from doing the work: choosing an architecture, seeing where it fails, and measuring what actually improves it. ATLAS and NEXUS are my way of sharing that knowledge and experience openly, with clear explanations, honest trade-offs, and code you can inspect. I hope they give you the confidence to question defaults, test your ideas, and build systems people can rely on.
