In this session, we will explore two very different approaches to software development. On one side, Vibe Coding—a new paradigm where AI helps us build by “vibing” with ideas and iterating quickly without focusing too much on specs. On the other side, Spec-Driven Development is a structured methodology where detailed requirements guide the entire coding process. We will compare the strengths and weaknesses of both, see where each approach fits best, and discuss how developers can combine them effectively. Whether you’re curious about the future of AI-powered coding or passionate about the software design discipline, this talk will provide fresh insights and practical takeaways.

We will become familiar with both methodologies, learn about the advantages and the disadvantages each of them has, and review cases suitable for each one of them.

The meetup will also include small demonstrations for using Claude Code, Cursor, and Kiro.

This meetup is free, online, and will be delivered in English. No previous experience with software development is required. Everyone is welcome!

Spec-driven development places the specification at the center of the software lifecycle, ensuring clarity, consistency, and alignment before the first line of code is written. In this session, we will explore how the Kiro IDE enables this approach by turning structured specifications into working code. We’ll look at the benefits of collaboration, error reduction, and long-term maintainability, and compare this method to more traditional coding practices. If you’re curious about the next generation of development tools and how they can improve software quality, this talk will give you both insights and practical examples.

Apache Spark has become one of the most popular frameworks for large-scale data processing, thanks to its speed, simplicity, and flexibility. In this session, we will introduce Spark’s core concepts, explore the differences between RDD, DataFrame, and Dataset, and demonstrate how Spark can simplify complex data analytics tasks. Whether you are entirely new to Spark or looking to strengthen your big data skills, this talk will give you a clear and practical jump start into the world of distributed data processing. During this session, we are going to use the Scala programming language.

Join us as we explore the upcoming Java 25 feature defined in JEP 502 — Stable Values. This new capability enables developers to defer initialization of immutable data while still allowing the JVM to treat that data as constant (and apply constant-folding and other optimizations). In this meetup, we’ll dig into the motivation behind stable values, how they bridge the gap between lazy initialization and performance-tuned immutability, show code examples, discuss use-cases (such as caches, pools, services), and what this means for modern Java architecture and startup performance. Bring your questions, and let’s dive into deferred immutability together! This meetup will be delivered in English.
