DDD Rhein/Main – Domain Models Unbound, Unbent and Unbroken

Nach einer langen pandemiebedingten Pause wollen wir nun das DDD-Rhein/Main Meetup wieder aufleben lassen.
Dazu konnten wir Marco Heimeshoff mit einem Vortrag zu „Domain Models Unbound, Unbent and Unbroken“ gewinnen.

Gut 5 Jahre ist es her, dass wir unserer erstes DDD Meetup Rhein/Main hatten. Damals gab uns Marco Heimeshoff einen Deep Dive in das Thema Event Storming.
Nach einer langen pandemiebedingten Pause wollen wir nun das Meetup wieder aufleben lassen. Auch dieses Mal wieder hat sich Marco dazu bereit erklärt den Auftakt zu machen und sein Wissen mit uns allen zu teilen!

Liebe Grüße von Marcus Franz und Sven-Torben Janus

  • 18:30 bis 19:00 Uhr – Ankommen, Begrüßung, Kennenlernen

  • ab ca. 20:00 Uhr – Get-Together, Diskussionen (wir sorgen für Drinks & Fingerfood)


At the beginning of almost every domain driven design journey stands the context mapping with it’s socio-technical relationships. Using various collaborative modelling methods to derive an initial design, companies often get hung up on the first draft and stick with it’s trade offs for far too long. Inertia of team topologies and technology make change increasingly painful and the revelation that was promised becomes the prison we hold our selfs in.
Let us ditch the idea of a framework, an architecture or agile method that brings us freedom and start building our own dynamic set of roles, relationships and patterns to create and master an ever changing system.
Inspired by the unFIX model by Jurgen Apello we will adopt the mindset and extend it to our domain model and build our own toolbelt, now and forever.


Marco Heimeshoff is a trainer, coach and software developer from germany. He co-organizes KanDDDinsky, a conference about the art of business software and founded the german DDD community in 2013.
Marco Heimeshoff has an unhealty relationship with Domain Driven Design, and won’t leave any stone unturned once you lend him an ear and sticky notes.
He believes that life long learning, focus on language and empathy are the three pillars of quality development. Frustration about the same old methods of working together and developing solutions lead him to Domain Driven Design, agile softwaredevelopment, functional programming and CQRS with event sourcing. With ten years of experience in these topics he helps teams to change and learn in all things from code to culture.
