🗣️ Przemysław Pokrywka: Ports and Adapters for People on Tight Schedules
Focus on software architecture is not always associated with pragmatism in common perception. Terms such as architecture astronautics and the ivory tower stereotype highlight the perceived disconnect between many architects and the realities of day-to-day code maintenance. Too often, architectural patterns are applied with insufficient understanding, leading to cargo-cult adoption and increased waste in the software development process. When applied in the right context, however, certain architectural approaches can be powerful enablers. In this talk, I would like to share the story of a serverless application in which elements of the Ports and Adapters architecture made a tangible, positive difference.

🗣️ David Lebl: Complexity is a Sin, But Hexagons Forgive
A visual journey from spaghetti to sanity. This talk traces how cognitive load accumulates in unconstrained codebases, how domain-driven design and bounded contexts restore order, and how hexagonal architecture provides a practical, forgiving structure for real-world systems — all laid out on a single zoomable canvas where every example links back to the bigger picture.
