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 Repo: github.com/pwyczes/ddd-...

Greetings from Syberia.

The season is open. 🏂

Mark my words. Reverse Prompt Engineering will be a thing soon. #AI

Long weekend ahead. 😎

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. Read: www.eventuallyinconsistent.com/2025/10/in-a... #CQRS #DDDesign Pls RT.

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

Good morning 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?

Boa Lisboa.

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.

Good to be back. Summer time in #Kraków #Cracow

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 🧠

Ouch. 😅

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.

We just scheduled a Craft-IT ticket raffle (and a discount) at dddkrk.pl meetup: www.meetup.com/ddd-krk/even...

Polish "Wind and Truth" part 2 covers were revealed. For the first time, I think the hardcover (number 2) is much, much, much better than the paperback (number 1). (However, the paperback for part 1, with Szeth is still a masterpiece: bsky.app/profile/pwyc...) #StormlightArchive #WindAndTruth

Great Thread! 👇 Also, the drift can happen more than once, causing more than 2 models to exist. (Including the modernized one(s)) 😏

I've recently started using the term "valuable slice" over "vertical slice". If you're delivering value in a slice then often you will have a vertical slice anyway. Focus on the delivering something valuable, not on how it slices your architecture.

Last year at the @dddkrk.pl #DDDesign meetup we finished #TeamTopologies reading club. Today I came across this 👇 cool article by Piotr Kacała. www.linkedin.com/pulse/team-t... I hope it will be valuable to you too! I find the 8th Principle very close to my heart: "Foster Continuous Discovery".
