About

Not a blog.
A memory.

Chumania started as a place to write down things I figured out — so I wouldn't have to figure them out twice. How to center a column. How to sign a document digitally. How to think about a problem.

Then AI came along and changed everything. Now the lessons are bigger, the stakes are higher, and the journey is worth sharing. This is that journey, documented in real time.
