Democratic Architecture
In today’s dynamic and rapidly evolving technological landscape, software architecture must move beyond rigid, top-down constraints to truly empower development teams. Democratic Architecture proposes an approach centered on defining architecture through high-level quality objectives rather than prescriptive implementation details. This philosophy fosters a flexible architectural framework that respects team autonomy, leverages diverse expertise, and adapts to unique development contexts.
By embracing Democratic Architecture, organizations can cultivate systems that are both adaptable and resilient, while nurturing collaborative engineering cultures in which architecture guides rather than dictates. Decoupling architectural intent from specific implementations enables teams to respond fluidly to changing requirements and technological shifts, ensuring long-term system sustainability and alignment with evolving business goals.
Domain-Driven Design Hands On
It is not easy to write software that solves complex business problems. We all have learned that, some of us the hard way. Domain-Driven Design offers tools and methods to "tackle complexity in the heart of software". After a short introduction to DDD, drawing from Conway's Law and the Cynefin Framework, we will collaboratively model an interesting domain using Event Storming and Story Mapping. Then you will transform selected parts into code using the design patterns of DDD (Value Object, Entity, Aggregate, Repository, Factory, Service, and Domain Events). Further topics covered include Bounded Contexts, Strategic Design, and Hexagonal Architecture. To conclude the workshop, we will discuss the question: What about CRQS and Event Sourcing?
Introducing CQRS and Event Sourcing into Legacy Applications
Building green-field applications with Event Sourcing and CQRS is pretty well-understood today. Introducing these concepts into legacy application is a whole different story, however. The legacy database claims to be the source of truth, the language is polluted by technical terms used in existing systems, and developers are tempted to add more and more special cases to the existing software. This presentation condenses several years of experience from introducing Event Sourcing and CQRS into legacy applications (and minds), presenting deep insights into challenges, solutions, and attempted solutions. We will discuss what has worked, and what did not work.
Democratic Architecture
In an increasingly diverse and fast-moving technological landscape, software architecture must evolve beyond rigid prescriptions to truly empower development teams. Democratic Architecture reframes architecture as a set of high-level quality goals and guiding principles, intentionally minimizing prescriptive implementation details. By doing so, it establishes a flexible architectural framework that respects team autonomy, domain expertise, and the realities of varied technical environments.
This approach fosters adaptable and resilient systems while cultivating collaborative development cultures in which architecture guides decision-making rather than enforcing it. By decoupling architectural intent from specific implementations, Democratic Architecture enables organizations to respond more effectively to changing requirements, emerging technologies, and shifting business priorities, ultimately improving long-term system sustainability and strategic alignment.
Domain-Driven Architecture
Architecture is often shaped early on by technological choices, such as frameworks, patterns and deployment models. But what if we reversed that process? What if architecture emerged only from the quality goals of a system?
This talk introduces Domain-Driven Architecture: an approach that derives architectural structure directly from non-functional requirements, or quality goals. Inspired by Domain-Driven Design, this approach explicitly applies those principles to architectural decision-making rather than just modelling.
Using real project examples, including successes and failures, I will demonstrate how systems can evolve over time, emphasizing loose coupling and intentional boundaries. This approach enables systems to change in a targeted and controlled way without becoming locked into premature technology decisions.
The presentation is aimed at software architects and developers who view architecture as an evolutionary discipline that can be consciously designed, evaluated and refined as the domain and its requirements evolve, rather than as a fixed blueprint.
Harvesting Ideas – A Collaborative Journey into Domain Design
How can we design a system that delivers ultra-fresh produce from local farms to customers without the need for central warehouses, unnecessary delays or wasteful detours?
In this interactive, hands-on workshop, we will collaboratively explore and model the innovative operations of Produce Paradise, a fictitious start-up that is reimagining the farm-to-table delivery experience.
Rather than following a single 'big name' method, we'll mix and match techniques such as Event Storming, Architectural Roleplay, Domain Storytelling, Example Mapping, and User Story Mapping, along with any approaches you bring from your own toolkit. Starting with real-world artefacts such as emails and business plans, we will uncover the story behind the business, understand its context and visualise how it operates. Together, we will map the logistics journey, identify key challenges and shape potential solutions using a blend of collaborative modelling practices.
This workshop is intended for software developers, product managers, domain experts and anyone tackling complex business problems. No prior experience with modelling techniques is necessary, just curiosity, creativity and a willingness to co-create.
Come harvest fresh ideas and grow sustainable solutions - together.
The Developing Salesman
Software developers are not just builders of features. We are creators whose work deserves to be understood, valued, and championed. Yet because software is largely invisible, communicating its impact is often harder than creating it. How, then, do we make the value of our work unmistakable?
In this session, Stefan Priebsch examines the often-neglected skill of conveying value in a world where technical excellence alone no longer guarantees recognition. Through candid insights, real-world stories, and practical communication techniques, this talk reframes selling not as manipulation but as translation: the art of turning technical achievements into outcomes that matter to customers, colleagues, and decision-makers.
Attendees will learn how to present their work in language that resonates with stakeholders, advocate effectively for their teams, and position themselves as trusted experts rather than invisible implementers. Whether you’re negotiating priorities, arguing for architectural investment, or promoting your next big idea, you’ll leave equipped with the confidence and tools to make your work seen, understood, and appreciated.
