Thank you. :)
I did. I want it to be based on real-world experience, not just applying patterns from books.
If you have any comments, I'd love to hear them. :)

AI-Assisted DDD (Without Asking Anyone) People often treat DDD as all-or-nothing: either you do “the full thing”, or you don’t do it at all.  ¯\_(ツ)_/¯ And that’s one of the main ...

I blogged over the weekend:
"AI-Assisted DDD (Without Asking Anyone)"
www.eventuallyinconsistent.com/2026/02/ai-a...

DDD is often treated as all-or-nothing, but you can start with tiny steps today.

I made 2 skills for AI agents:
- Value Object
- Factory

Inside you there are two wolves. One of them knows SQL. This is the WHERE-wolf.

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 🧠

Just walked past #DevoxxPL.
Funny — I’m not attending, but it’s literally on my daily walking route.

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.

Right now?

AI is a powerful tool.
But it’s not a shortcut.
Not magic.
Just another part of the toolbox.

Use it with intent — and with eyes open.

I still think it’ll improve.

Models will get faster. More accurate.
Maybe we’ll trust them more.

Or maybe we’ll just get better at supervising more changes — safely.
