Last year, I gave a live coding session at @devoxx.com, demonstrating how to make software more sustainable using hexagonal architecture. I'm thrilled to see that the recording has reached 16k views. 1/6

Aujourd'hui c'est la première édition de Nantes Craft! J'ai eu le plaisir de présenter mon live coding sur l'architecture hexagonale devant une salle pleine ! Merci à toutes et tous d'être venu me voir vous pouvez retrouver mes slides et mon repository en commentaire 👇

Excited to speak at @devoxx.com 2025 in Antwerp with @tpierrain.bsky.social 🎙️ Live coding the Hive: building a microservices ready modular monolith 👇 ⭐ Fav the conference page and save our session: m.devoxx.com/events/dvbe...

✨ After our 1st talk on the #theHive pattern with @julientopcu.com (building a microservices-ready modular monolith)… …We’re taking it to the next level: live-coding it at @devoxx.com ! 📌 Don’t miss it — add our session to your fav here: m.devoxx.com/events/dvbe2...

Thrilled to be back at @devoxx.com this year. I’m live coding The Hive with @tpierrain.bsky.social, an architectural pattern for building a microservices-ready monolith. And guess what? We’re on Friday! Is the AI planner biased or what? 😂 m.devoxx.com/events/dvbe2...

The biggest risk of vibe-coding is unintentional vibe-modelling The model is software's heart, bringing value to users and ensuring it will last over time. A well-crafted model is challenged against business expertise, not merely the result of a set of specifications

I'm really pleased to announce that I'll be speaker at @newcrafts.bsky.social 2025 🥳 With @josianchevalier.bsky.social, we will present our brand new talk for the first time in France: "Model Tension Heuristics: Preventing Accidental Design Debt"

And now at @breizhcamp.org : Hafsa El Maizi from @shodo.io, about CI/CD pipelines concepts I can already related with the "as a developer, I noticed that CI/CD pipelines are often obscure for devs" introduction — (sadly) heard/saw that so many times recently

Thrilled to be back @devoxxpl.bsky.social this week with 2 live coding sessions! Join @josianchevalier.bsky.social‬ and me on Thursday 17:25 for Model Mitosis: Stop Choosing Wrong Between Microservices and Monolith Then, kick off your Friday 10:10 with a hands-on dive into Hexagonal Architecture

Just had an amazing time at ‪@dddeu.bsky.social‬ I presented a new talk with ‪‪@josianchevalier.bsky.social‬ "Model Tension Heuristics: Preventing Accidental Design Debt" in Antwerp. Thanks for the great feedback on this challenging topic! We're thrilled you enjoyed it! slides.com/julientopcu...

Just enjoyed "the most dramatic talk this morning" @dddeu.bsky.social presented by the 'High Elf' @julientopcu.com and 'Gollum' @josianchevalier.bsky.social about the journey to "The Grey Havens", intertwined with model tension heuristics and accidental design debt. 😍 Awesome #DDDEU 🥰

In our brand new talk, Model Tension Heuristics, we'll discuss these tensions and how to detect and address them to prevent accidental design debt. Join josianchevalier.bsky.social and me at Elisabeth Hall, Friday, June 6, 12:00 @dddeu.bsky.social‬ If you're into evolving systems, see you there!

Writing code isn’t just machine instructions; it’s modeling a domain. George Box's insight: "All models are wrong, but some are useful", reminds us models simplify, not eliminate complexity. But when do models stop being useful or become harmful? Over time, models face tensions like: 👇

My talk on implementing hexagonal architecture with Java and Spring Boot is now live on YouTube ! You can find also the slides and my repository here 👇

Thrilled to return to #CraftConf as a speaker in Budapest! Join @tpierrain.bsky.social‬ and me for our talk, "The Hive: Crafting a Scalable, Flexible Architecture for Growing Complex Domains" 🎙️ Unveil the secrets with us on May 30th at 14:45 on the pink stage!

Just a reminder: Domain-Driven Design (DDD) is NOT a tool. Too often, people reduce it to "a way of writing code" and compare it to CQRS, Event Sourcing, or Clean Architecture.

Exciting update! #CraftConf 2024 sessions are now live on YouTube! Dive into Model Mitosis, a cutting-edge strategy for iteratively splitting and refining software models. Unlock the flexibility to decide when to spin off into multiple services. youtu.be/g6_-p-Bpy-E...

Bonsoir les devs, j'espère que vous avez passé un bon week end. Demain dans "Quoi de neuf les devs?" vous pourrez lire l'interview de Jonathan Salmona qui est le CEO @shodo.io à demain, bonne nuit 😴 et bon courage à la team de nuit !!

Hexagonal architecture session by @julientopcu.com. @devoxx.uk

Excited to present "Hexagonal Architecture in Practice: Live Coding for Sustainable Apps" at @devoxx.uk this Thursday! Join me at 16:20 in the auditorium for a live coding session. Discover how Hexagonal Architecture can boost adaptability, and effectively manage technical debt!

"Le pattern Hive : une stratégie de modularisation pour votre monolithe modulaire ou vos microservice" avec @tpierrain.bsky.social et @julientopcu.com #MiXiT

J'ai le plaisir de présenter aujourd'hui avec @tpierrain.bsky.social "Le pattern Hive : une stratégie de modularisation pour votre monolithe modulaire ou vos microservices" lors de @mixitconf.org 2025. Rejoignez-nous en Amphi Hamilton à 11h30 !

While yesterday’s talk wasn’t recorded, you can catch our slides, repository and a previous session’s recording here 📽️ Recording: youtu.be/_0AJM1oErU8?... Slides: slides.com/julientopcu/... Repository: gitlab.com/beyondxscrat...

We just wrapped up our first #ExploreDDD Conference in Denver, and what an incredible journey it’s been! 🎉 It was a true honor to join the largest Domain‑Driven Design conference in the US, and we’re so grateful for the warm welcome and thoughtful feedback on “Model Mitosis”

Pour la première fois depuis longtemps, je rate @devoxx.fr cette année 🥲 Mais on a quand même réussi à m'amener en amphi bleu aujourd'hui 😁. Un grand merci à @garnier.wf pour la mention concernant mon talk sur OAuth 2.1 😍 (merci à @nathangc.bsky.social pour la photo !)

💥 Struggling with microservices complexity? Whether it's Distributed Monoliths or tangled monoliths, unclear boundaries are often the root cause. Let's discover Model Mitosis, an iterative way to clearly define boundaries without premature splitting at Explore DDD, Wed 5:15 pm in room Crystal B&C!

I just realized that my session at J-Fall last November marked my 100th conference talk 🥳 Over the past 6 years, I've covered 16 subjects, traveled widely, and collaborated with incredible people. I'm honored to be part of this community!

See you Tuesday at 11:05 AM in Room 4, be prepared to revolutionize your approach with “Model Mitosis: Stop Making the Wrong Choice Between Microservices and Monolith” mobile.devoxx.com/events/vdz2...

Join @josianchevalier.bsky.social and I on Tuesday at 11:05 AM in Room 4 @voxxedzurich.bsky.social to explore a dynamic approach for iteratively splitting your business model, without getting tangled in spaghetti code or creating a dreaded “distributed monolith.”

🚀 The last two days were such an unbelievable experience, something I was not expecting to happen during my career I had the honor to be invited to give 2 talks🎙️at the CERN alongside CERN employees and renowned international speakers, during the 2024 millésime of VoxxedCERN
