I’ve spent a decade building AI as a Stanford computer scientist and coding AI systems at Meta & at a startup acquired by NVIDIA. I’ve always loved to teach, and now I get to create educational videos to share the skills, understanding, and intuition I’ve worked years to develop with you.  For my (free) 10 Days of AI Basics series + more, DM me GUIDE and I’ll share my video walkthrough guide with you.
