Pins are my favourite swag. So versatile. I can add them to jackets/scarves/sweaters/bags and so collectable. Here is the #AMxDC23 one, with a Kotlin one I got from one of the sponsors at #appdevcon and my favourite Habitica Mage pin.

If you're at #appdevcon Amsterdam this May, I'll be whipping out the ol' OpenAPI toolset, making sure that also Mobile App developers can benefit from full cross-programming language type safety.

Extremely happy to report that I’m invited to speak at #Appdevcon / #Endpoint, an IT Conference in #Amsterdam. https://appdevcon.nl/schedule-2023/

It’s no secret I’ve been busy developing software from 1997 to 2022 and the last few years I spent time talking about ethical subjects such as Privacy or the Environment.

This talk will hopefully inspire decision makers but also each and every single developer. There’s no reason for them to not help me save the world, and not only code-line-based.

Retoot! :)

I'm excited to announce I'll be giving my "Decision-making for developers" talk at AppDevCon
/ Endpointcon this year!

Next week we have a new Ingewikkeld Session. I'll be doing a session on the basics of #DDD. I've worked on several projects that implemented DDD, but to actually explain it is a whole different beast.

An interesting challenge to work on this. And once I've prepared the session, I can reuse big parts of this for my introduction to DDD talk at #appdevcon/#endpointcon

Happy to announce that I'm speaking at #appdevcon/#endpointcon on May 12th. I'll be doing an intro into Domain-Driven Design: https://appdevcon.nl/speaker/stefan-koopmanschap/
