Software Architecture: The Bad Parts
In this talk, I will demonstrate how so-called good practices combined with a shallow understanding of the domain can create a dangerous illusion of control.
Using a real-world example from the Connected Health domain—specifically, liver cancer risk alerting—I will show how a noun-driven design approach leads to excessive coupling and brittle systems.
The talk will explore common architectural pitfalls such as context violations, database coupling, domain leakage, and mixing read and write models. I will also challenge a popular industry belief by explaining why Clean/Hexagonal Architecture is not an architecture.
Attendees will leave with a clearer understanding of how design decisions shape system behavior—and how easily “best practices” can fail when the domain is misunderstood.
Mechanics of talking Must-have soft skills of Solutions Architect.
You hear it everywhere: if you want to be a modern Solutions Architect and not get left behind, you must know GenAI, DDD, EventSourcing, EventStorming, or EventModelling.
It’s only half the truth.
The other half—without which you simply won’t succeed—are soft skills.
I’ll share my non-technical experience working as a Solutions Architect and talk about:
- How to structure your statements
- What techniques to use to increase self-confidence during important meetings
- Why small talk matters
- How to impress a client
- How to present solutions clearly
- How to reduce stress levels
Soft skills are just like technical skills: you can improve them.
It’s not easy. Especially if you want to be more than an average Senior Engineer and keep your position safe in the coming years.
Events are domain atoms. Why does event sourcing help greatly in healthcare?
Ready to transform your domain modeling? Event sourcing shifts focus from stale states to immutable facts—the true atoms of your domain.
In Connected Health, this is revolutionary: when medical formulas or risk assessments evolve, you can reinterpret entire patient histories without touching your data!
Discover how event sourcing combined with the decider pattern creates thinner aggregates that speak pure business language.
Stop fighting your domain model—embrace events and unlock a more maintainable, business-aligned architecture!
