Skip the math degree. Ship the system. Repeat.
How to actually use this
Don't try to learn all 13 at once. Stages 01–04 (fundamentals → agents) get you building. 05–08 make it production-grade. 09 is the software-engineering floor under all of it. 10–12 widen your range. 13 is what compounds — ship in public from day one, not after you "finish." Pick the lowest-numbered stage you can't yet do confidently, and start there.
Want this built for your business, not just learned?
