DDDx — Domain-Driven Design eXchange 2021

Tuesday, 8th - Wednesday, 9th June, Online Conference

14 experts will be speaking. Starts at 12:00 PM BST (11:00 AM UTC)

Join us for the return of the DDD eXchange, a 2‑day online conference exploring the world of Domain‑Driven Design.

Over 2 days, you'll learn from thought leaders, architects and developers as you connect with likeminded people to share the skills, insights, lessons developed from your modelling, design and development projects.

Learn from experts and peers alike as you discover the best tools and strategies to tackle your next big challenge. We'll be looking at topics like the newest best practices for Strategic DDD in a remote-work world, the relationship between business models and software architecture, and how to make the most out of modelling and patterns.

The 2021 DDD eXchange will be an online conference hosted on the Hopin platform.

At Skills Matter, we’ve chosen to see the events of the past year as a challenge to make our content and community more inclusive and accessible to all. Beyond the COVID‑19 pandemic, we have a vision of a community where knowledge sharing and skills transfer are not limited by physical barriers.

We are excited about the opportunity to truly welcome the global DDD community to this year’s Domain-Driven Design eXchange.

We hope to see you there!
