About Me
I am a software architect and developer with more than 35 years of experience in a broad range of business domains. As a leading expert in Domain-Driven Design I champion simplicity.
I consult and teach around Domain-Driven Design and reactive software development, helping teams and organizations realize the potential of business-driven and reactive systems as they transition from technology-driven legacy web implementation approaches.
I am the founder of the open source (OSS) Kalele XOOM platform, a set of DDD-friendly distributed computing tools that simplify concurrent, reactive, event-driven, and microservices architectures, supporting the JVM. (See source code.)
My Kalele team and I created DomoRoboto to improve individual and team experience with DDD and related challenges, including software architectures. With DomoRoboto you get team agile strategic experimentation, discovery-based learning, and software modeling. DomoRoboto is an all-in-one tool that gives you strategic, rapid, learning for teams using Domain-Driven Design and Architecture modeling.
In addition to my best-selling books—Strategic Monoliths and Microservices; Implementing Domain-Driven Design; Domain-Driven Design Distilled; and, Reactive Messaging Patterns with the Actor Model—I was commissioned by Pearson/Addison-Wesley as curator and editor of my own Vaughn Vernon Signature Series.

NEW! Implementing DDD v3.0
Go beyond the theory of Domain-Driven Design and see how teams can actually use DDD to accelerate their strategic initiatives in a way that helps them design for business competitive advantage with this three-day workshop. Emphasis is placed on software design in source code with agile knowledge acquisition and de-emphasizes throwing technology at strategic business software initiatives.
Domain-Driven Design Monoliths to Microservices
Microservices architecture is a clear trend. A trend is not hype, but it’s also not mainstream. You must not ignore the Microservices trend, but you must learn why this architecture is trending and how to successfully adopt it, or decide not to. This 3-day workshop steps you through the definitions and drivers to help you become oriented with this approach to distributed computing.
Reactive DDD
A two-day, intensive, design and programming workshop first builds your foundation with the Actor Model using vlingo/actors. This workshop then expands your understanding with advanced application and system design approaches, using Domain-Driven Design and microservices. A hands-on workshop with many practical exercises. Students are strongly encouraged to engage using the VLINGO/PLATFORM components.
Deep dive workshop series
A highly sought after series, these deep dives into topics such as Aggregates, Process Management and Sagas, and Reactive Architectures, will accelerate your learning and skills growth.
DDD for Modern Architectures
Systems today are far more likely to be distributed, especially due to the ever-increasing popularity of the cloud and microservices, and they’re also increasingly asynchronous and message- and event-driven, and thus reactive. In this 2-day course you will learn how to deal with these and other influencing conditions using domain-driven design.
Event-Oriented DDD
This intensive, two-day, hands-on workshop teaches you Domain-Driven Design within an explicitly event-oriented microservices business domain. You will learn both strategic and tactical design. This workshop is specially designed for mid-level and senior software developers and architects who are interested in applying event-driven and microservices architectures using DDD.
Managing DDD
Thorough and exhaustive, this one-day, hands-on workshop consists of short lectures, exercises, and innovative game-play leading you to a clear understanding of how to leverage DDD, putting it to use on your Agile project. It’s a class that is well balanced for business experts and technical stakeholders alike.

- Why EventStorming practitioners should try Domain StorytellingDomain Storytelling is a collaborative modeling technique that highlights how people work together. Its primary purpose is to transform domain knowledge into business software. This purpose is achieved by bringing together people from different backgrounds and allowing them to learn from each other by telling and visualizing stories. If you practice EventStorming, you might see […]
- Adopting an API Design-First ApproachThe design of a web API is a separate and critical step of software delivery. The process of API design requires communication that extends beyond the developers that will deliver the API. When executed properly, an API design process helps to course-correct wrong assumptions while aligning business, product, and technology teams on the essential elements […]
- Implementierung eines Supermarkt-Self-Checkout mit DDD – Ein Forschungsprojekt auf Basis von XOOMBrick and Mortar 2.0 — no shoplifter, but tech hipster Supermärkte mit Self-Checkout — also Bezahlen ohne Kasse und Kassierer — gibt es schon eine Weile. Seit ein paar Jahren kann man so auch in Deutschland einkaufen. Technisch funktionieren diese Self-Checkouts so, dass man vor dem Verlassen des Supermarktes alle Waren an einer Kassierstation scannt […]
- Implementing Supermarket Self-Checkout using DDD — A Research Project based on XOOMBrick and Mortar 2.0 — no shoplifter, but tech hipster Supermarkets with self-checkout – i.e., payment without a cashier – have been around for a while. For a few years now, it has also been possible to do your shopping this way in Germany. Technically, self-checkouts work by scanning all the goods at a checkout […]
- Architecture vs ModelOne of the biggest problems with business software is that architecture gets promoted more than the domain model. Further, most domain models are ordinary, and could be implemented by school students for a lot less cost than the 7-9 figures often spent. Yet, often the software architecture supporting a model—almost certainly anemic—is generally over engineered. […]
