Spec-driven Development
Wie KI alles (und nichts) verändert
SPEAKER: Simon Martinelli COMPANY: Martinelli GmbH
KEYWORDS: AI, Lessons learned, Concept
KI beschleunigt die Softwareentwicklung, aber wir haben immer noch das alte Problem: Code wird zur Quelle der Wahrheit. Was wäre, wenn wir das umdrehen würden?

Implementierung von DDD leicht gemacht mit Spring und jMolecules
SPEAKER: Stefan Heinzer COMPANY: ELCA Informatik AG
KEYWORDS: Architecture, Concept, Technology, Tools
Das Versprechen des Domain-Driven Designs (DDD), "Komplexität im Herzen der Software zu beherrschen“, ist sehr reizvoll. In der Praxis übernehmen jedoch viele Projekte nur ausgewählte Konzepte und Techniken. Besonders bei der Umsetzung in Code fallen Entwickler oft in traditionelle Muster wie datenzentriertes Design oder „Smart UI“ zurück, bei denen die Domänenlogik über alle Schichten des Codes verteilt ist – auf eine Weise, die schwer oder gar nicht mehr kontrollierbar ist.

I Didn't Know You Could Do That With Java Streams!?
SPEAKER: François Martin COMPANY: Karakun
KEYWORDS: Lessons learned, Technology, Tools
Over years of working with many Java codebases, I see the same mistakes being made over and over again when it comes to using Streams. Most Java developers are familiar with the basics, but many do not know about advanced features that could make their code easier to read and perform better at the same time. In this talk, I will share the common problems I faced and how I used advanced Stream techniques and Collectors to improve those codebases.

Back to Basics: Crafting Quality Software in the Age of Complexity
SPEAKER: Scott Gerring COMPANY: Datadog
KEYWORDS: Lessons learned, Performance, Technology, Tools
In the age of microservices, developers often find themselves drowning in incidental complexity – making countless decisions about queues, serverless technologies, databases, Kubernetes clusters, and much more. This complexity can overshadow the foundational task of writing clear, maintainable, and robust code.
