The Ultimate NumPy Course: Zero to GPT in Pure NumPy

I spent months building the NumPy course I wish existed when I was learning.

**393 cells. 18 chapters. Zero to GPT in pure NumPy.

One interactive notebook that takes you from "what is an array?" to implementing neural networks, transformers, and GPT from scratch — no frameworks, no hand-waving. Includes 11 bonus deep-dives, a real research paper reproduction, and portfolio-ready projects with interview talking points.**



Free preview (Ch1-2) on GitHub — run it in Colab, no install needed.

Full course on Gumroad — pay what you want, starting at $9.
