Workshops

Getting the Specs Clear

Specifications in joint effort, visually and in business language. Each workshop feeds into the next, moving from understanding to a clear, codeable specification.

Domain Storytelling

Introduction and overview

Domain experts tell their stories and capture them visually, building a shared ubiquitous language that the entire team speaks fluently.

Event Storming

Understanding and scoping

Collaboratively explore domain events, commands, and actors to build an end-to-end overview of what happens in the business and get a first indication of where the boundaries lie.

Context Mapping

Organisation and breakdown

Define boundaries between subdomains and clarify how they relate to each other.

Event Modeling

Clear solution specification

Triggers and reactions, information flow, and a visual blueprint that translates directly to code.

Technology

Technology & Architecture

An AI-native stack built on open standards. Seamlessly switch between human and AI development — the code is indistinguishable.

│

Vertical Slice Architecture

Isolated features, repetitive patterns. Actual agility and maintainability at linear cost. Each slice is independent and self-contained.

⇒

Event Sourcing

Agility, compliance, and audit logging. Full history of every state change. Never lose data, always know what happened and why.

∗

AI-First Development

Automate chores, facilitate decisions. The architecture is designed from the ground up to leverage AI at every step of the development process.

⊕

Open Source

Freedom, Eurostack, run anywhere. Pure code, no licenses, no products, no platforms. You own everything and can deploy wherever you choose.

≡

Predictable Process

Clear and predictable code is good code. Repetitive patterns and a predictable development process mean fewer surprises and consistent delivery.

◆

Functional Core

Java and Postgres at the core. Pure business code, integrated via ports and adapters, runs on any cloud or public infrastructure. Detailed observability is built in from day one.

Key Principles

What this approach delivers

The combination of collaborative specification and AI-native architecture produces concrete, measurable outcomes.

✓

Parallel Independent Development

Vertical slices enable teams to work on features simultaneously, at constant cost, without stepping on each other.

✓

Business Code Separated from Technical Code

Strictly separate business functionality code from technical execution environment code. Change one without breaking the other.

✓

Ready for Future Requirements

Embrace future requirements without degradation of solution quality. The architecture bends, it does not break.

✓

Monitoring and Observability

Monitoring and observability visualised in the specification model. You see the system health in the same language you designed it.

✓

Scale Without Impact

Scale as you need, without impact on functional code. Infrastructure concerns stay separate from business logic.

✓

Side-Effect Free Maintenance

Isolated slices mean fixing or updating one feature never causes regressions in another. Maintenance without fear.
