I have not discovered anything new. I have applied established architecture and engineering practices that I've been following for 15 years to using Claude Code.
Domain-Driven Design started with Eric Evan's "blue book" in 2003 and continued with Vaughn Vernon's "red book" a few years later. Event Storming workshops and event sourcing data storage have also emerged as important tools.
I am just a practitioner. Eric, Vaughn, Paul Reyner, Alberto Brandolini, and a few other architects lead.
My DevArch guardrails is a toolkit to follow these practices.
