Today we're hosting another @isaqb.bsky.social Software Architecture Community NL meetup at the @openvalue.eu Utrecht office, with two talks about the intersection between software architecture and AI. Interested? Join the community at www.meetup.com/isaqb-nl/ !

Just presented "Making significant Software Architecture decisions" at @devoxx.com Belgium. Thanks everyone for joining! Slide deck: www.slideshare.net/slideshow/de...

Go serverless with Quarkus, GraalVM Native Image and AWS Lambda with @bjschrijver.dev! The talk will cover the migration process, development, deployment, and cost considerations, with a demo to help attendees get started themselves: m.devoxx.com/events/dvbe2...

Every developer starts by learning. The real growth happens when you start sharing. 🚀 At #dev2next, @bjschrijver.dev's keynote showed how this simple cycle transformed his career — and how it can transform yours too. 📸 Photos from the session below!

The J-Fall 2025 call for papers is open for one more week and will close on September 1st, end of day. Please share your proposal(s) via sessionize.com/jfall25!

I'll be back on stage at @devoxx.com in Antwerp in October to present three sessions: a talk about software architecture, a serverless deep dive and a speaker coaching session. Hope to see you here!

Played around a bit with MCP integration with @quarkus.io, @langchain4j.dev and Ollama during the yearly hackathon with the @openvalue.eu Utrecht team. Built a small example setup with 2 @quarkus.io apps - an MCP client that connects to an MCP server over HTTP: github.com/bertjan/quar...

Moving from Twitter to Bluesky? Here are a couple of useful tips including migrating posts and people you followed 👌🏻

This is clever. Great work @theo.io 👏 bsky-follow-finder.theo.io

💡 Tip: You can set your website as your username on Bluesky! This is one form of self-verification, and we especially encourage official organizations and brands to do this! Examples include @npr.org @react.dev @duolingobrasil.com.br. Here's our guide for how to do this:

Is it just me or is BlueSky gaining traction over Twitter? 😉

I was terribly nervous to be one of the opening #keynote speakers at J-Fall last week... but it turned out quite well. 😊 Here is a snippet of one of my favorite moments in the talk.💡 It looks great on this video made by @bjschrijver.bsky.social.

It’s a wrap! Thanks to all speakers attendees and the whole team for amazing @jfallconf! #jfall

I don't really keep track of this, but I just saw that my playlist of recorded conference talks contains over 50 recordings with over 200.000 views in total! That's.. more than I expected 😉 Thanks for watching!

These pictures capture the essence of why I speak at conferences. And it's even better when friends join the fun 😆 Thanks @TCoolsIT, @BrianVerm, @JoostenRosanne and others for helping out with my #Devoxx session "Getting started with speaking"! 📷by the amazing @dDoutsiopoulos

Had a great time presenting "Generic or specific? Making sensible software design decisions" for a full room at @Devoxx Belgium today. Missed it? Slides are here:

If you’re doing trunk based development and work remote (or hybrid), how do you do code reviews?

Looks like @nljug @jfallconf sold out in 20 minutes ... #jfall
