My name is Michel van den Berg and I'm an independent software architect specialized in building distributed systems.
I work under the company name 'Promontis', which is a contraction of the Latin words 'pro' (for) and 'montis' (of the mountain; my last name). In my spare time, I contribute to open source projects and work on a startup named Stylister.
For fun I watch TV series (anything Marvel) and play the piano.

Udi Dahan's Advanced Distributed Systems Design
Designing large-scale distributed systems is hard. While new technologies make it easier to comply with today's communications and security standards, they don't auto-magically give you a robust and scalable system. See how companies like Amazon and eBay run their systems and learn how to:
- Avoid common pitfalls in distributed systems
- Use loosely coupled messaging communication
- Identify and allocate business logic to services
- Decompose services into layers, tiers, assemblies, and processes
- Design for service management and monitoring in production environments
Greg Young's Advanced CQRS & DDD Workshop
This advanced CQRS training dives deeper into discussion on process managers, sagas, and advanced messaging patterns
Gregory Young (author of EventStore) coined the term “CQRS” (Command Query Responsibility Segregation) and it was instantly picked up by the community who have elaborated upon it ever since.

NLP Practitioner, Psychology psychotherapy Commucation
We start with a review of your proposed architecture (which usually goes on two days) at which point, with the feedback you'll receive, we schedule a full week architecture & design workshop where we refactor the solution.
The product of that first week usually includes the identification of top-level business services, their break-down into business components, the use of existing systems and their orchestration within each business service, and the message choreography between them. We usually have about 15 to 20 UML/BPMN diagrams per service at this level.
At that point we usually follow up with twice-weekly conference calls (about an hour each) to make sure that the design effort doesn’t get stuck or take a wrong turn. 2-3 months after that, we usually have another 2 day review. After that, usually we move to a mode of an hour call once or twice a month.
