Criteria Debt

For Product Engineers

Product, not code

Code is a means, not the end. Your craft is to decide, write what holds up, and ship beyond the merge.

  • 6 dimensions of the craft: criterion, sustainable code, collaboration with AI, ownership, repositioning
  • 4 printable templates (canvas, 1:1, checklist, journal)
  • The system that remains yours when AI sits in the editor

Why do I share this for free?

Elevate the industry

The more engineers build better software, the better the industry is for everyone.

Share knowledge

I've learned a lot from the community. This is my way of giving back what I've received.

Real impact

I'm more motivated by contributing to many teams than focusing on just one.

"The best code I've ever written is the code that helped other engineers write better code."
