Want to build better business software by aligning your code with your culture? Join DDD expert and business software artist Marco Heimeshoff for this intensive workshop exploring the technical relationship between code, culture and architecture — you'll discover how to model and implement software from a business perspective.
Software that is aligned with the business needs of your customers is hard to build, and it is even harder to optimize for correct domain behaviour, execution performance and scalable information distribution at the same time. Distributing the model with microservices often falls short on the promised benefits and can leave you with a distributed monolith.
The secret to a successful implementation lies in the correct segregation of read and write models from a domain-driven perspective, and connections between them implemented with semantic events. Join Marco Heimeshoff for this virtual workshop as he’ll guide you to build semantic models with a high alignment between business and code.
In this course, you will learn how to scale your application so that any number of queries can be handled, while also maintaining a behaviour rich domain model that can deal with complex scenarios. Discover how Event Sourcing enables you to build highly cohesive and decoupled modules and changes the way you write and communicate about tests forever.
These patterns will help you to put your energy where the business value is, by letting you partition your team by their expertise and outsource the busy work. Drawing from Domain-driven design concepts, write code with Command Query Responsibility Segregation and learn how Event Sourcing tells a story in domain terms.
Keep your software system design in line with your organisation’s needs, improve readability, and strengthen your communication with key stakeholders.

This workshop is for Architects and Senior Developers with a strong interest in Domain-Driven Design and modern message-driven architectures.
Regardless of your experience in either Object-Oriented Programming, Functional Programming or other paradigms, all you need is the will and ability to build software with a focus on business behaviour.
To benefit from this DDD, CQRS & Event Sourcing course, you should have existing professional software development experience. Some prior knowledge about DDD, CQRS and Event Sourcing is helpful, but this is not a prerequisite.
