My workshops are well-balanced: they contain equal portions of theory and practice. You can start implementing advanced concepts right-away and verify the correctness of their results with the trainer.

Classes are limited to 15 participants to give everybody an equal opportunity to learn.


Concepts in plain sight

When explaining a technical concept, it will not be buried beneath a pile of framework code or implementation details. The concepts are in plain sight, ready for you to grasp.

Sandbox projects contain back-to-basic PHP code, so when you've finished your training, you can then use any framework you like to let your code blossom.


Advanced topics

I offer lots of advanced workshop topics. We don't focus on the basics, we dive straight to the core of a concept.

There are a lot of different subjects we can cover, it's up to you to select which will be most useful for you or your team.

The Tactical DDD workshop by @matthiasnoback was beyond awesome! Had at least 4 a-ha moments! Really good! #phpbnl17

So glad I attended @matthiasnoback's 2day workshop on advanced application development. Already looking forward to the next workshop.

Upcoming workshops

Domain-Driven Aggregate Design

2-day workshop
Thursday September 20th, 9:30-17:00
Friday September 21th, 9:30-17:00

Utrecht area (NL)

In this 2-day workshop, you'll go back to the basics of object-oriented programming and learn to apply core principles of Domain-Driven Design to your domain objects: aggregates, consisting of entities and value objects.

You'll learn how to progress from domain knowledge to a functioning domain model, and use unit testing along the way to describe the expected behavior of your objects.

The program

  • Object-orientation, distilled
  • Event storming session: the warehousing domain
  • Modelling session: determine types and behavior
  • Implementing an entity and value objects
  • Aggregate design rules
  • Working with domain events and eventual consistency

Advanced Application Testing

2-day workshop
Thursday October 18th, 9:30-17:00

Many web applications out there don't get the testing love they need. Some test suites only have unit tests; they run fast, but will never prove that features as a whole function correctly. Some test suites only have functional tests; they run very slowly, they often fail for no reason, but they can prove that all the wiring is correct too. There is a middle ground, which we'll be aiming to reach in this 2-day workshop. We take an existing application with only functional tests and "tease out" other types of tests. We thereby:

  • Increase the speed and predictability of the test suite as a whole,
  • Reduce the need for functional tests,
  • Set a standard for web application test suites, which you can apply at home (or at work) too. All of this will be rooted in some pretty interesting software architecture theory (i.e. ports & adapters and layered architecture).

The program

  • System tests
  • Architecture: ports, adapters, layers
  • Integration tests
  • Unit tests
  • Acceptance tests
  • Test doubles and architectural boundaries
  • Spotting design issues with feedback from tests

Building Autonomous Services

2-day workshop
Thursday November 22nd, 9:30-17:00
Friday November 23rd, 9:30-17:00

In this 2-day workshop we’ll dive into the topic of Autonomous Service design, with a sandbox project containing several interdependent services. These services send messages to each other, and they call each other to retrieve data. In other words, they’re not autonomous at all. We’ll figure out some ways in which we can invert dependencies and leverage a messaging solution to achieve autonomy after all.

The program

  • Guidelines of designing for autonomy
  • Event-based service integration
  • Solving the "command" issue
  • Read models and projections
  • Solving the "query" issue
  • Bounded contexts
  • The Reservation pattern
  • Reporting
