Published a new blog post this morning:
“In the Age of AI, Your Data Has a Future — But Only If It Has a Past”
Companies using #EventSourcing will train #AI on their stories, not snapshots.
That gap compounds every day.

Goodbye @axoniq.bsky.social
These were two intense days with Event Sourcing and AI.
Now it's time for a rainy weekend in Amsterdam. 🙂

Hello folks, I’ve been away recently — traveling, working, resting a little, but mostly unplugged.
Getting back in the groove and curious:
What’s been happening around #DDDesign, #CQRS, and #EventSourcing?

I was writing a type-safe Fluent Builder. Cursor casually dropped the name:
“Curiously Recurring Template Pattern.”
I laughed. I’ve done that before. I just didn’t know it had a name.
LLMs are great at connecting intuition with terminology. Not solving for you, but revealing what you already knew.

One agentic coding tip I'm using is asking the agent to prefix its responses with an emoji to confirm it has read a certain file.
It's good - when I see certain emojis I know for sure that it has certain rules files in context.
Picked this up from Llewellyn Falco at Craft Conf 🧠

From an engineering perspective, software wants to be decoupled. From a business value perspective, software wants to be deeply interconnected. That's the fundamental friction that software design, and Domain-Driven Design specifically, attempts to address.

Three weeks ago, I joined an internal AI hackathon.
The rule: one day, build anything work-related — but rely almost entirely on AI.
Obviously, I chose to refactor a core, complex part of the system.
You know me — I like a bit of #DDDesign chaos.
