Agenda
18:00 – 18:15 Introduction and organizational matters
18:15 – 19:15 Krzysztof Kąkol – Revolutionizing application modernization with AI
The presentation will explore practical aspects of using generative artificial intelligence to accelerate application and code modernization. Real-world project case studies will illustrate the use of GenAI for tasks such as code explanation, automated refactoring, legacy system migration, and architecture optimization – significantly reducing development time and costs. The session will also cover encountered challenges, as well as best practices and future trends in AI-supported modernization.
19:15 – 19:25 Q&A
19:25 – 19:35 Break
19:35 – 20:35 Arkadiusz Zdanowski – Triangles, Ducks, and Icebergs: a Review of Data Lakehouse Technologies for 2026
The presentation analyzes the landscape of Lakehouse technologies from a 2026 perspective. It provides an in-depth comparison of table formats (including Delta Lake, Apache Iceberg, and DuckLake), focusing on differences in metadata management, transactional capabilities, and schema evolution. The session also covers architectural concepts such as Data Mesh, Data Fabric, and the Modern Data Warehouse, clearly distinguishing market trends from real-world business applications. The presentation focuses on key trade-offs and decision-making criteria, grounded in experience from real production deployments. It helps assess when a given architecture truly makes sense and when it is merely an expensive buzzword, offering a comprehensive, vendor-neutral view of the evolution of data technologies—free from marketing hype.
20:35 – 20:45 Q&A
20:45 – 22:00 Pizza & Networking
