I tell stories about a.i., robotics, and interactive media with code and care -- and I transform them into products _

My name is Caer Sanders. This is my studio, With Caer.

I've earned the title of world champion roboticist and published my first book at 18. Since then, I've created educational robotics platforms with Google, architected AI and data infrastructure for Wayfair, and built agentic AI platforms at Thoughtworks.

Through my independent studio work, I've patented cryptographic consensus protocols for distributed systems like robot swarms and microservices, and created some games.
