This event is for people who join the event in person at Sentry (https://sentry.io/welcome/). If you join the event remotely, please RSVP here: [https://www.meetup.com/dotnet-austria/events/313495808](https://www.meetup.com/dotnet-austria/events/313495808) This meetup is organized by DotNetDevs.at (https://dotnetdevs.at/). **Abstract** C# is a strongly typed programming language, used to communicate expectations in a statically verifiable fashion across the .NET ecosystem. There is a set of language features that can be enabled by satisfying a particular shape rather than inheritance or interface implementation. In this session we look at compiler-recognized patterns such as: \* using custom types in \`foreach\` \* applying \`await\` to custom types \* tuple-like deconstruction \* implicit \`Index\` and \`Range\` support \* collection initializers and expressions for user-defined types Join this live coding session for a deep dive into pattern-based features in C# and how to make reusable types more convenient and idiomatic to consume. **About Eva Ditzelmüller:** Eva is a Software Engineer at Radancy in Vienna, where she works with C#, Rust, and AWS. Her path to tech was not linear: she started with a B.A. (Hons) in Acting and worked as a production assistant and performer in London before moving into computer science. Today she regularly hosts a live-coding stream and speaks at conferences including NDC Oslo and Techorama. She was named a JetBrains Community Contributor and enjoys making software engineering fun and accessible for people from all backgrounds. **About Stefan Pölz:** Stefan is a C#/.NET developer in Vienna and works at Sentry. He shares practical software engineering content through his FlashOWare channels and regularly contributes to the .NET community as a speaker. Location, Food & Drinks are sponsored by Sentry.

**Walk & Talk** Willst du auch mehr Bewegung in dein Leben bringen? Und dich dabei noch gut unterhalten, so dass die Zeit verfliegt? Dann bist du hier genau richtig, denn mir geht es genauso. Alleine ist langweilig und die Zeit vergeht nicht, daher hab ich mir Walk & Talk überlegt. Inspiriert wurde ich durch die Walk & Talk Gruppe in Hamburg, wo ich mehrere Male dabei war als ich in Hamburg lebte. Unterschiedliche Menschen treffen sich einmal in der Woche für einen flotten Spaziergang und unterhalten sich dabei. Ich liebe es neue Menschen kennenzulernen und auch bekannte Gesichter wiederzusehen, dann geh ich ganz nebenbei und das macht auch noch Spaß.😊 **Walk:** Wir brauchen einfach regelmäßige Bewegung und ich weiß selbst, wie schwierig es ist, diese in den Alltag zu integrieren. Deshalb ist dieser Walk genau richtig. Nach diesem Spaziergang fühlst du dich einfach wohl, fit und entspannt. **Talk:** Das Reden kommt ganz von selbst beim Gehen. Du kannst über alles reden, egal, ob privates oder berufliches, alles was sich ergibt ist willkommen. Und wenn du keinen Bock aufs Reden hast, dann gehst du alleine, auch das ist völlig in Ordnung. **Wie das ganze abläuft:** * Die Teilnahme ist völlig kostenlos. * Wo: U6 Spittelau (im Freien), Richtung Donaukanal, Ausgang Josef-Holaubek-Platz, direkt vor dem Fernwärme-Turm (https://maps.app.goo.gl/XwAayz4FQe2EW8WK9) * Wann: Wir treffen uns dienstags um 13 Uhr, egal, ob bei Regen, Sturm und Kälte oder bestem Sonnenschein – Walk & Talk findet nahezu JEDE Woche statt außer ich bin mal im Urlaub. * Wir starten pünktlich und beginnen mit einer kurzen Vorstellungsrunde. * Wie gehen am Donaukanal entlang von Höhe Spittelau bis zum Schwedenplatz und zurück. * Ca. 7 Kilometer sind wir unterwegs und unterhalten uns dabei mit interessanten Menschen. Dabei kannst du neue Bekanntschaften schließen, dich inspirieren lassen, von Projekten erzählen oder einfach nur smalltalken und die frische Luft genießen. Alles ist erlaubt. * Nach ca. 1,75 Stunden sind wir wieder am Ausgangspunkt zurück. * Bei einer Teilnahme von über 5 Personen gehen wir in Paaren und wechseln diese alle 10 Min. Wenn du aber lieber alleine gehst, ist das auch vollkommen in Ordnung. * Für alle, die einfach mal etwas Neues ausprobieren wollen. **Bist du bereit?** Dann komm mit! **Start bei U6 Spittelau Ausgang Donaukanal** Nochmal: um **PUNKT 13.00 Uhr dort sein**, denn **nach kurzen Vorstellungsrunde gehen wir gleich los. Sei pünktlich, denn die Gruppe wartet nicht.** Du musst nichts vorbereiten oder dich gar anmelden, komm einfach vorbei. Ausreden gibt es nicht. Geh mit und freu dich auf eine tolle neue Erfahrung. **Wer macht es?** Ich bin Marie Meyer-Marktl und Ideengeberin, Host und Organisatorin von Walk & Talk. Ich unterstütze seit 2019 Menschen dabei Freude ins Arbeitsleben zu bekommen und bin Business und Life Coachin. „Strahle, wenn du an deine Arbeit denkst“, ist meine Vision für jedermann und jedefrau. Privat merkte ich, dass ich endlich wieder mehr Bewegung brauche – und das klappt am besten gemeinsam mit anderen Menschen. Sei dabei bei Walk & Talk und bring Bewegung in dein Leben. **Do you speak English? Then welcome to Walk & Talk!** This event is suited for all people who like to connect to other people and like to walk. The beauty of this regular event is that you are in the nature and you walk around 7 kilometers. In the meantime, if you feel for it, you talk, if not, you just walk. You do something for your health, get to know new people and you will feel much better. It’s FREE, all you need to do is to show up this Tuesday at no later than 1 pm at the U6 Spittelau exit to Donaukanal.

Bring your JS interest and a good vibe! Everybody is welcome & feel free to share this invitation! **Talks and info:** All details: [https://viennajs.org/en/meetup/viennajs-march-2026](https://viennajs.org/en/meetup/vienna-js-march-2026) **Timetable:** * 18:00: Gathering, food & drinks * \~18:45 - 19:00: Start of the first talk **Talks:** \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- 🗣️ Daniil Rabizo ▶️ AI Is Just JavaScript: Building Powerful Agents with Google ADK & RAG Most valuable company data is private: documents, presentations, internal notes, yet AI tools can’t use it out of the box. In this talk, we’ll show how easy it is to build an AI agent that can securely read Google Drive data and answer real business questions using Retrieval-Augmented Generation (RAG). Through a simple JavaScript demo with Google ADK and Vertex AI, you’ll see how private docs and slides can power use cases like internal knowledge assistants, onboarding bots, management Q&A, and support automation without complex ML infrastructure. This session is for developers, founders, and tech leaders who want practical, production-ready AI use cases and a clear understanding of how to turn existing company data into useful AI agents. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- 🗣️ Priscila Oliveira ▶️ Comprehend First, Code Later: The AI Skill I Rely On Daily Literally everyone is vibe coding. It's about letting AI write, commit, and ship code you never even read. Perfect for prototypes and side projects - no argument there. But what happens when you're working in a million-line codebase where you need to understand before you change? Quality code still matters. It is widely stated in the software development community that developers spend 70–80% of their time reading and understanding existing code, not writing new code. We now have an incredibly smart tool - so why not use it for exactly that? So I went straight to the data - 239 of my own messages from daily work at Sentry. What I found flipped the narrative: my #1 use of AI wasn't generation. It was comprehension. Whether navigating unfamiliar code or reconstructing past decisions from commit history - AI became the teammate who never gets tired of my questions. In this talk, I'll show you the loop that actually makes me productive in a large, complex codebase: understand first, then say 'go ahead'. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **🗣️Want to give a Talk?** ▶️ [https://viennajs.org/en/participate/give-a-talk](https://viennajs.org/en/participate/give-a-talk) **Location:** Sentry Jakov-Lind-Straße 5, 4. OG (Entrance next to Max & Benito) 1020 Wien **Sponsors:** 🙏 Sentry Sentry is the market leader in the error monitoring space and like many startups with engineer founders, Sentry was born out of frustration with technology. David started Sentry as an open-source side project in 2008. We started in a small community — the Django web framework — and over time expanded our technology to support dozens of other platforms, including browser JavaScript and mobile applications. Fast forward to today, we're a $90M Series E company with a $3B valuation and 200+ employees on a mission to help developers write better software faster, so we can get back to enjoying technology. As one can see, the adventure continues to be exciting as we bring our developer-first Application Monitoring to more customers and industries worldwide. Consider us for the ride!

If you are interested please contact us via [viennajsmeetup@gmail.com](http://viennajsmeetup@gmail.com/) or at [viennajs.org.](http://viennajs.org./) \*\*\* **Don't forget to RSVP!**

Join us at our March Meetup event for great talks, discussions and beers. Big thanks to Posedio for hosting! **Agenda**: * Doors open 5:30 p.m. * ***Talk 1: 6:00 to 6:30 p.m.*** * **Speaker**: Christian Kirchknopf * **Title**: Building a Secure In-House LLMaaS Platform: BRZ's Approach to AI for Federal Government * **Abstract**: In this talk, I demonstrate how we (BRZ) have developed an Enterprise-Ready LLM-as-a-Service platform that provides government applications simple and secure access to Large Language Models – without dependency on public cloud providers and without data sharing with third parties. Through a unified API, AI applications gain access to locally operated models (e.g., Mistral) or optionally to public cloud providers – depending on requirements, costs, and data protection needs of the workload. Discuss the architectural and product decisions: vLLM as a GPU-optimized inference engine, a central AI gateway that enforces multi-tenancy, security, and comprehensive observability. A brief live demo will show how applications and developers access AI models through a single API – with token-based quotas per tenant and intelligent routing. An experience report from an exciting AI infrastructure project in Austria. * **Break: 6:30 to 6:45 p.m.** * ***Talk 2: 6:45 to 7:30 p.m.*** * **Speaker**: Damjan Gjurovski * **Title**: What is A(I) platform? * **Abstract:** In this talk I will discuss the need of platforms in the age of AI. I will outline some hard-won lessons from my previous experience in developer platforms, data platforms and SRE teams, and discuss how these apply to AI platforms. On the one hand, I will make the argument that AI makes certain aspects of platforms and platform engineering unnecessary, but on the other hand reinforces the need for other platform components. Finally, I will attempt to differentiate between the two new platform types out there – AI platforms and AI Engineering platforms and discuss the capabilities and requirements for each. * **Networking**: start 7:45 p.m.

**THIS MEETUP WILL BE IN-PERSON 🕺** **We're starting at 17:40 this time! 🕒** **What to expect:** 🗣️ Two or three speakers 👥 Meet old and new friends from the community 🍕 Free food 🎉 Open-end and free drinks afterwards ✔️ Just RSVP! Agenda: * 17:30 - Doors open * **17:40 - Welcome by &‌‌amp and SQUER** * 17:50 - First talk * 18:35 - Break * 18:50 - Second talk * 19:35 - Food, Drinks & Networking * 21:30 - Doors closing 👂 **Talks:** 🗣️ Boris Wrubel **Developing Selenium Tests with AI: Practical Insights from Real-World Automation Projects** 🗣️ Philipp Greitbauer **Modern Java Packaging: From Slim Images to Swift Runtimes** 🧑‍💻 **Speakers:** **Boris Wrubel** has over 20 years of experience in software testing, specializing in test automation within agile environments. His expertise spans major projects in banking, telecommunications, and the public sector. For a decade, Boris was part of the Industrial Software Research Group (INSO) at Vienna University of Technology (TU Wien), where he also organized and lectured in the "Software Testing" course. He holds a degree in Business Informatics, with a focus on project and quality management from TU Wien, and has contributed to open-source test automation projects in recent years. *Talk description:* He will share an honest field report from an ongoing project: How does my day-to-day work with Selenium change when generative AI is added as a support tool? Using concrete examples, I demonstrate how AI-based tools help with writing, revising, and understanding test code - for example, by suggesting test cases, proposing refactorings, or assisting with debugging. The focus is not on technology promises, but on real-world experience: Where does AI save time? Where does it lead you astray? And how does this change the role of the test automation engineer? The talk is aimed at anyone interested in the use of AI in quality assurance, with a focus on practical insights, pitfalls, and concrete learnings from everyday project work. **Philipp Greitbauer** is a software engineer at &‌‌amp, a Vienna-based software consulting company. While he works across the full stack, his focus lies in the backend using Java, Kotlin, and Spring Boot. Driven by a curiosity that often leads him down technical "rabbit holes", Philipp is committed to building proper technical foundations. He prioritizes utilizing existing tools to their full potential rather than reinventing the wheel, ensuring that systems are built efficiently. His daily work involves helping clients evolve their systems, drawing on his experience in the banking industry and the public sector. *Talk description:* In this session, we will look at modern strategies for efficiently packaging and running Spring Boot applications. If you are currently building Docker images by simply copying fat JARs, there are several newer tools and techniques in the Java ecosystem that can significantly optimize both your deployment process and runtime performance. We will explore the use of Buildpacks and Spring AOT, alongside JVM advancements like Project Leyden and Java 25’s Compact Object Headers. The talk will also contrast GraalVM with optimized JVM runtimes using AOT Cache or CRaC, examining how these different approaches address the challenges of startup time and resource usage. \-\-\-\-\-\-\-\-\-\-\-\- **Can't find what you like?** **Got something to say?** 📢 Send us your thoughts in the comments.

The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** Web Forms gave .NET developers a powerful abstraction for building reusable UI controls long before design systems were a thing. Web Components finally bring that same idea to the browser natively. This session explores how the Web Forms mindset translates into Custom Elements, Shadow DOM, and HTML templates. We’ll examine how Web Components enable design systems that work across frameworks, how they differ from server‑driven controls, and why they’re becoming a foundational layer for modern UI. Whether you’re maintaining legacy apps or building greenfield projects, you’ll leave with a practical understanding of how to apply familiar patterns in a modern, standards‑based way. **YouTube Link** TBA

This group is brought to you by the Dianetics and Scientology life improvement center.

Builders, creators, architects, admins, consultants - come one, come all. This one's for you. We're bringing a little friendly competition to the Columbus ServiceNow community while highlighting the cool things people have built on the platform. Five presenters will take the stage to showcase something they've built, solved, designed, or imagined on the ServiceNow platform - and a panel of judges (plus YOU, our amazing audience) will score them live. So basically, America's Got Talent but make it ServiceNow's Got Talent. Bring a notepad if you'd like 'cause you'll definitely be learning something new. Each presenter gets 10 minutes max to wow the crowd with: • A demo • A real-world business solution • A bold idea • A UX transformation • Or a creative use of the platform Judging Criteria: 🏆 Business Value 🚀 Innovation ✨ User Experience This event is about celebrating ideas, sharing knowledge, and showing how ServiceNow can drive both business impact and meaningful user value. Come learn. Come support. Come get inspired. Refreshments and bites will be provided. And maybe next time… you’ll be on stage.
