Is It Cake? Vertical Slice Architecture + AI + Dynamic Consistency Boundary

In the game show "Is It Cake?", contestants guess which object is real and which is a perfectly decorated cake. The test is simple — take a knife and cut through it.

Architecture is similar. Vertical Slice Architecture promises independent pieces of a system. But will your slices pass the knife test? Teams adopt VSA, yet their slices are still coupled through shared models or Aggregates — developers block each other with every requirements change. The folder structure pretends to be modular, but the knife reveals a monolith.

In this presentation, we'll walk through a concrete VSA maturity path: from slices organized only by folders, through extracting dedicated models per slice, all the way to fully autonomous slices built on Dynamic Consistency Boundary and Event Sourcing — where each feature can be developed, tested, and deployed independently, with no risk of collisions between developers. We'll apply Domain-Driven Design and Event Modeling in practice.

The result? A system where new functionality doesn't require constant changes to shared code, blocking each other, and resolving conflicts. Shorter time to delivering business value and an architecture that scales with the team — not against it.

And what about AI? Artificial intelligence doesn't guess context — it needs it. A mature slice is a perfectly tailored context served on a silver platter.

Come if you want to:

• learn the maturity levels of Vertical Slice Architecture and find out where your project stands;

• understand why a "real slice" is more than just a folder in a project;

• see DCB in action (Axon Framework 5 + Kotlin) — slices without static aggregates;

• stop blocking each other on the team with every new feature;

• see how VSA makes collaboration with AI easier;

• finally cut without fear.
