Very cool anyway! Can I expect a youtube video about this soon?

He is not "your avg dev" and it took him 4 months with llm.

This is not a seal of approval for you to go and command all your developers to move to Claude code/codex/any other ai coding tool fully.

I'm looking at you - any avg CEO of a startup.

I start with a high level design md doc which an AI helps write. Then I ask another AI - whether the same model without the context, or another model - to critique it and spot bugs, gaps and omissions. It always finds obvious in hindsight stuff. So I ask it to summarize its findings and I paste that into the first AI and ask its opinions. We form an agreed change and make it and carry on this adversarial round robin until no model can suggest anything that seems weighty.

I then ask the AI to make a plan. And I round robin that through a bunch of AIs adversarially as well. In the end, the plan looks solid.

Then the end to end test cases plan and so on.

By the end of the first day or week or month - depending on the scale of the system - we are ready to code.

And as code gets made I paste that into other AIs with the spec and plan and ask them to spot bugs, omissions and gaps too and so on. Continually using other AI to check on the main one implementing.

And of course you have to go read the code because I have found it that AI misses polishes.
