Zwischen Legacy und Lakehouse - Unser Weg zur modernen Datenplattform
Wir zeigen die Entwicklung der Datenplattformen der DKB – von der On-Premises-Welt hin zur Cloud – und werfen einen Blick darauf, wie Open Table Formats (OTF) die Datenlandschaften der Zukunft verändern können. Dabei geben wir einen kurzen Überblick über die Grundlagen von OTF und vertiefen anhand eines Demo-Beispiels den Einsatz von Apache Iceberg in Verbindung mit Ab Initio. So beleuchten wir die Stärken und aktuellen Schwächen dieser Technologie.

Modulith instead of Monolith
Modularizing applications around the domain is key to building scalable and maintainable systems. This talk presents a flexible alternative using application modules with the Spring Boot Modulith framework. Attendees will learn how to structure applications with clear boundaries, improve maintainability and embrace modular design without losing alignment with domain-driven principles.

Workshop: Getting Started with Kubernetes
Ever felt personally victimized by YAML? In this 50-minute beginner-friendly workshop, we'll demystify Kubernetes without summoning a SRE. You'll set up a local cluster, deploy a (cloud native!) demo app, and learn just enough to sound confident in meetings. No prior experience needed - just curiosity and a willingness to copy-paste kubectl commands with reckless optimism. By the end, you'll have a working app, a mild sense of accomplishment, and a newfound respect for containers that don't hold leftovers. P.S. I sadly can't help with Windows: Please bring a Linux or macOS machine.

Team Topologies - the leading approach to organizing business and technology teams for fast flow of value
Team Topologies is an approach to designing team-of-teams organizations for fast flow of value. The approach provides a pattern language and a thinking model, which allows you to identify the team-of-teams design most appropriate for the target architecture and fast flow of value. In this talk I present the core ideas: the four fundamental topologies; the 3 team interaction modes; the principles & (anti)patterns.

Faster to Instant Payment: The Microfrontend Way
This talk shares the journey of introducing a microfrontend architecture in DKB's web banking platform to enable faster delivery and team autonomy. By breaking the frontend into independently deployable modules, we accelerated the rollout of key features like instant payment. Rather than focusing on technical internals, the talk highlights how architecture supported speed, flexibility, and cross-team collaboration in a real-world product setting.

Workshop: Chihuahua or Muffin? Develop your own AI
Can you tell the difference between a chihuahua and a muffin? It's harder than it sounds - and that's the challenge we'll tackle in this interactive workshop. Using Python and machine learning, you'll build your own image classifier to distinguish between visually similar objects. Whether you want to classify animals, documents, or desserts, you'll learn how to train and fine-tune your own model for maximum accuracy. Bring your curiosity and get ready to teach your AI to see the world (almost) like you do! Required: Basic knowledge in programming with Python or a similar language.

Enhancing security in microservice architectures: A case study on scanning with Veracode Collections
In this presentation, we will explore the use of Veracode Collections to enhance security in microservice architectures, which, while enabling scalability and flexibility, also introduce significant vulnerabilities. We will provide an overview of the security challenges associated with microservices and demonstrate how Veracode Collections can automate the scanning process for comprehensive security assessments. Through a practical case study, we will share insights on integrating scanning into CI/CD pipelines, interpreting results, and addressing identified vulnerabilities. Attendees will gain valuable strategies for securing microservices and fostering a security-aware culture within their development teams.

How to Test Your AI! – Über die Bändigung von LLMs und RAG-Systemen
Large Language Models (LLMs) und Retrieval-Augmented Generation (RAG) revolutionieren die Entwicklung intelligenter Anwendungen, stellen jedoch hohe Anforderungen an Zuverlässigkeit und Testbarkeit. Der Vortrag gibt Einblicke in Testmethoden, die im Rahmen der Qualitätssicherung solcher KI-basierten Systeme zum Einsatz kommen. Ergänzt wird dies durch konkrete Erfahrungen und Lessons Learned, die beim Aufbau des Digital Agent, unserer virtuellen Assistenz für den Kundensupport, gewonnen wurden.

How to Create Successful X-Border teams
This session dives into the real secret behind high-performing distributed tech teams: culture. With a mix of humor, sharp insights, and real-world case studies - from GitLab's wins to Boeing's missteps - we'll explore how cross-border collaboration, when done right, becomes a strategic superpower. You'll walk away with practical tools, fresh perspectives, and a clear understanding of why the future of tech is human, cultural, and borderless. Why attend? This isn't just theory - it's being put into practice. We'll spotlight the launch of DKB Bank's new Valencia hub, a growing initiative that's testing how cultural strengths and a collaborative mindset can shape smarter, more connected global teams. If you're curious about the future of distributed work, this is the session to watch.

AWS-Migration – Herausforderungen und Lösungsansätze
Using the example of DKB's internet banking migration, we will demonstrate how complex challenges in connecting distributed systems to the AWS cloud were successfully solved. The focus will be on scenarios such as access from the FITS network to RDS instances in non-routable subnets, requirements for fixed IP addresses, DNS restrictions, and handling RDS failover. The presentation highlights the architectural decisions made, interim solutions used, and the gradual transition to a long-term sustainable, scalable, and highly available connectivity architecture in a regulated banking environment.

Workshop: AI-Driven Product Design: From Idea to Interactive Prototype
Creating responsive prototypes in tools like Figma or Sketch is often time-consuming and usually results in temporary throwaway products that quickly become outdated and serve only as visual references. In this workshop, participants will learn how to strategically leverage generative AI to move quickly from a rough product idea to a well-structured and sustainably usable product documentation. Together, we'll use AI to create essential artifacts (e.g. product vision and user journeys), which will be refined through iterative feedback loops between humans and AI. Finally, we'll use the generated documentation to rapidly build a static HTML/CSS/JS prototype that provides a solid foundation for actual application development.

Barrierefreiheit by Design – Wie wir Accessibility in unsere Systeme einbauen
Barrierefreiheit ist kein Bonus; sie ist ein Qualitätsaspekt und beginnt weit vor dem ersten Audit. In dieser Präsentation zeige ich, wie wir Barrierefreiheit bei der DKB in unsere Architektur integrieren, mit praktischen Beispielen aus unserem Designsystem: von standardmäßig ARIA-unterstützten Komponenten über automatisierte Tests bis hin zur Integration in CI/CD und die Definition of Done. Ich berichte darüber, wie wir eine bereichsübergreifende Governance etabliert haben, wo wir gescheitert sind und was wir dabei gelernt haben. Diese Präsentation richtet sich an alle, die Barrierefreiheit nicht als reine Pflichtübung sehen, sondern als strategischen Hebel für bessere Produkte. Zielgruppe: Frontend-Entwickler:innen, UX-Designer:innen, Engineering-Teams, Product Owner, Accessibility-Verfechter:innen

Model Context Protocol: What it is And Why it Matters
In my talk I'll give an introduction of Model Context Protocol: - what it is (Think of it as a universal 'USB-C port' for AI, allowing AI models to access real-time information and perform actions consistently and efficiently beyond their training data.) - why it's important (It acts as a universal adapter providing a standardized, secure, and scalable way to connect AI models to external tools and data sources, enabling more powerful and context-aware AI applications.) - practical use cases (and how we can use it at DKB)
