Just published under Creative Commons BY-SA: the complete slide deck from my 2022 Software Analytics workshop. A deep dive into how data can help us understand and improve software systems. I believe this is becoming even more relevant in the age of AI. speakerdeck.com/feststelltas...

Sara Pellegrini will talk about killing the aggregate (volume 3). #KanDDDinsky #KDDD

About Event Sourcing & CQRS with @heimeshoff.bsky.social and @paulrayner.bsky.social in 30 minutes! youtube.com/live/4idWySy...

Have been looking forward to this talk coming out - had so much fun playing with the loopy causal loop diagrams, check it out 😀 Special thanks to @paulrayner.bsky.social for feedback and advice the night before this one! @dddeu.bsky.social #systemsthinking

In this talk Chris Simon will demonstrate the building of a range of causal feedback loops to visualise the underlying causes of the problems. With such visualisations we can advocate for the practices of technical excellence: 🎬 buff.ly/HADjm2P

ICYMI: I wrote about how your domains and bounded contexts don't map 1 on 1. #DDDesign verraes.net/2025/08/doma...

Claude Code agents handled the tedious bits while I focused on structure. Not magic, but saved me days of manual work. Full story: thepaulrayner.com/blog/2025/09/15/cleaning-up-93-grammar-paradigms-with-ai-agents/

Arrived in Boston today to facilitate an in-person Big Picture EventStorming workshop tomorrow and Wednesday. Curious what unexpected connections, ‘aha’ moments, and opportunities will emerge as the shared story is visualized on the wall.

Claude Code says it's done executing the Supabase/Stripe integration implementation plan. I clear the other CC session and have agents review *actual* progress and update the plan doc.

I’ve been working exclusively in Claude Code lately. For new features, I've typically spent no more than half a day (usually much less) drafting a plan in “planning mode,” then let it evolve as I build. Small slices, lots of iteration and learning.

After 6 wks of tinkering in Bolt.new and Claude Code, I’m down to the last mile before releasing BINAH, my passion project. Integrating paid subscriptions via Supabase + Stripe. Launch coming soon!

The entry in my claude.md that makes coding just that little bit more fun for me 😎 - **Task completion**: Always `say "Done"` when completing significant tasks

Very honored to be speaking at #AdaConf 2025 this Nov in Melbourne!

Experimenting with working with Claude Code in VSCode in two different sessions simultaneously, each working on different parts of the code base. I've been toggling between plan mode in one session while the other implements. It feels smooth so far. How has this approach worked for you?

🧵 I’ve reviewed conference talk submissions for +10 years. Here are my tips: (Side note, I've sinned against all these tips myself 🙃)

Excellent observation

Feature Flag Alternatives to consider: • Better Split (of user stories) • GoF Design Patterns • Domain-Driven Design • Strangler Application Pattern • Branch By Abstraction • Circuit breaker Dorra BARTAGUIZ at #DDDEU

This presentation contains so many distilled insights and modeling wisdom. And the slides are 🤌!

That’s how we do Domain-Driven Design for real: @ericevans0.bsky.social can’t resist but going in-depth into learning the domain of how LLMs work, down to monosemantic and polysemantic neurons! #dddeu

Thanks Tobias Goeshel for sharing your 4-month experiment of using AI agents to solve a domain problem directly! Lots of cues of what’s ahead of us, and all this thanks to last year @ericevans0.bsky.social talk! #dddeu

In this class, you will join Eric Evans and a small group of fellow participants to work on a real-world problem. There will be a domain expert from a complex domain. You will work with the group, lead by Eric, to interview the expert, create domain models, and design a solution:

A huge thank‑you to @paulrayner.bsky.social, @rebeccawb.bsky.social, @ziobrando.bsky.social, Joseph Yoder, Thomas Betts, @crichardson.bsky.social, Tobias Goeschel, Phillip Bohnenkamp and everyone we had the pleasure of connecting with, for making this event unforgettable.
