About us
Join our community-driven meetup in Vienna about everything in and around complex Java software projects. We strongly believe that exchanging ideas, discussing challenges, and exploring new features are key to progress as software engineers and enabling project success. Our discussions aren't limited to Java—we also dive into adjacent topics like software architecture, event-driven systems, or cloud infrastructure. Held at different local venues, our events prioritize open exchange and learning over being always right. All levels are welcome!

Breaking Up with My Default Stack🧑💻 Speakers:
Eva Schwarz - Tribe Leader & Senior Software Engineer at willhabenTalk description:
What happens behind the scenes when the lights blink red at Austria’s largest marketplace? This talk takes you on the full journey of an incident at willhaben - from the adrenaline of the first pager alarm to the relief of the fix, and finally, the crucial post-mortem. We will explore how we turn chaos into structured response, practice a blameless culture, and use every outage as fuel to build a more resilient platform. Join us to see how we ensure that a software failure today leads to a stronger system tomorrow.Patrick Favre - Software engineer with 15+ years of experience, starting with Java and evolving toward cloud-native architectures.
Currently a Lead Developer at Senacor Technologies, focused on building scalable systems in complex enterprise environments, with a strong interest in how cloud requirements are changing the way we choose our tech stacks.Talk description:
As software has moved toward cloud-native and cloud-first architectures, the constraints and priorities of our systems have changed.
In this talk, I’ll explore how that shift reshaped the way I evaluate technologies - as a Java developer at heart - and why I sometimes choose alternatives to the JVM, while still seeking the strengths I value from the Java ecosystem.Location, Food & Drinks are sponsored by willhaben 🫶
