**Designing the Next Generation of AI Experiences** AI products are evolving faster than ever. But while interfaces become smarter, trust, clarity, and usability often lag behind. Join us for an evening exploring how designers shape AI experiences people can actually understand, trust, and use with confidence. Together with leading voices from the design industry, we’ll discuss the challenges of designing for AI-driven products, emerging UX patterns, and what it takes to build meaningful human-centered experiences in an increasingly automated world. The evening will feature several keynotes, followed by a panel discussion and networking with Berlin’s design community. **Speakers & Talks** ## Speakers & Talks ​**[Rafaela Stamboroski](https://www.linkedin.com/in/rstamboroski/?utm_source=luma)** Model Behavior Designer for Joule at SAP ​**Talk: Guarding the Guardrails: The Designer’s Role as Behavior Becomes the Product** Designers have always created shared context: aligning people, decisions, workflows, and business goals around user needs. In AI-native products, this skill becomes even more critical. Strategy and systems thinking turn into behavior alignment: shaping how AI acts, responds, and collaborates with humans. ​This talk explores why the designer’s role is not shrinking in the AI paradigm. Instead, designers are moving upstream: defining guardrails, influencing product strategy, and helping businesses deliver AI value safely and meaningfully. ​**[Abanoub Awny](https://www.linkedin.com/in/abanoubawny/?utm_source=luma)** Sr. UX Designer & AI Innovator @ SAP Signavio, Founder of [Unblind UX](https://www.linkedin.com/company/unblindux/?utm_source=luma) ​ **Talk: Your Next User Isn’t Human** AI is no longer just a feature inside digital products. It is becoming an active participant in how products are used, interpreted, and operated. As agents begin to navigate workflows, consume system structures, interpret content, make recommendations, and collaborate with humans, design must evolve beyond screens and interactions. This talk challenges designers, product teams, and developers to rethink what “user experience” means when the next user of your system may not be human. ​**[Anna Herasymenko](https://www.linkedin.com/in/annaisdesigner/?utm_source=luma)** Staff Product Designer at Meta, working at the intersection of AI, systems thinking, and product craft. ​**Talk: Vibe Coding for Craft** AI products can't be designed in static tools. The behavior is the experience — and behavior only shows up when real APIs and real data are in the loop. Designing in Figma is like planning a meal with pre-chopped ingredients. Vibe coding is actually cooking it: discovering the oven runs slow, the recipe has a typo, a spice is missing. That gap between planning and cooking is where craft lives. ​This talk reframes AI-assisted coding as a repeatable workflow for designing AI experiences: stress-testing edge cases, surfacing the failure modes static design tools hide, and closing the gap between looks right and feels right. **[Kate Hofmann](https://www.linkedin.com/in/kate-hofmann-ux/?utm_source=luma)** UX design leader with an enterprise focus and experience building and managing large design teams and multimillion-dollar design portfolios. Worked closely with organisations like SAP, Boeing, Microsoft, UBS, DHL, Flexera. **Talk: The Last Dashboard. What enterprise software looks like when AI becomes the primary interface.** For decades we designed enterprise software around the same assumption that users must navigate dashboards, analyse data, interpret reports, and decide what to do next. For ±20 years we’ve been obsessed with reducing clicks, then reducing forms, reducing friction. But as software takes over more of the analysis and decision-support tasks - do users still need interface at all? What is left for UX to design, and what becomes the role of UX? **Agenda** **18:00 — Doors Open & Networking** **18:30 — Keynote Presentations** **20:00 — Panel Discussion** **20:45 — Community Networking** **Venue Host** Hosted by **[SAP Office](https://www.sap.com/germany/about/berlin.html)** in Berlin — a front-runner and thought leader in enterprise application software, focusing on innovating parts of the core business, exploring trends, and developing new technologies. **Hosts** This event is organized by [Projector Global Community](https://www.linkedin.com/company/projector-global-community/?utm_source=luma) ambassadors (by [Projector Institute](https://prjctr.com/en/about?utm_source=luma)): * [Emiliia Karpiuk](https://www.linkedin.com/in/emiliiakarpiuk/?utm_source=luma) * [Julia Savchuk](https://www.linkedin.com/in/yuliia-savchuk/?utm_source=luma) * [Yuliia Kovalova](https://www.linkedin.com/in/yuliiakovalovapm/?skipRedirect=true) **Photos & Video** Please note that we will be taking photos at this event.

The longest day of the year is comming and let's another Kotlin meetup. This time we geather at N26! **⚠️⚠️⚠️ Due to a venue policy please submit the following form for additional details. Without it, you won't be allowed inside the venue:** https://forms.gle/XjqVXkD3FARCM6jA8 **Line-Up:** 👉 **TestBalloon: Kotlin testing is easier (and more fun) than you think** *by Oliver Okrongli* You want an easier way to write tests? Parameterize tests in plain Kotlin? Reuse a series of tests? Easily extend own your test setup? Have first-class support on all platforms? All without struggling with a huge framework API? TestBalloon is a new test framework that brings the power of Kotlin to your test setup. With a small-surface API, a hierarchical test structure and an extensible DSL, TestBalloon makes Kotlin testing easy, even at scale. Oliver, the author of TestBalloon, will show testing patterns and strategies and lots of practical examples, ranging from simple unit tests with less boilerplate to advanced testing with coroutines and generated data. This talk is based on insights first presented at KotlinConf 2026 in Munich. At the end of this talk, you’ll be able to firmly the answer the question: "How can I master Kotlin testing with ease, and make my team release with joy and confidence, every time?" 👉 **One Topic to Rule 'Em All** *by Yonatan Karp-Rudin* Kafka delivered every event exactly once, in order, and lost nothing. So what broke? This talk follows that question into the gap most event-driven systems leave open: what actually guarantees the order your domain depends on, and what quietly doesn't. We start from a real log line, find the crack in an architecture that looks clean and ships fast, and rule out the fix everyone reaches for first. The cure turns out to be one sentence of domain thinking plus one line of config, though the Schema Registry will fight you on the way there. A live demo runs the bug and the fix back to back: same load, same hero, one change. If you build with Kafka, you have probably shipped a version of this bug. You will leave able to spot it and fix it before it pages someone. 👉 **TBD** **Speaker Bios:** 🗣 Oliver Okrongli Oliver has been shaping and creating software from backend to frontends. He is the author of TestBalloon, a next-generation Kotlin test framework. Before, he has helped to maintain Kotest, and contributed to several libraries of the Kotlin ecosystem as well as the Kotlin compiler. Can be found on GitHub (OliverO2) and the kotlinlang Slack (Oliver O). When not developing, he is most probably in deep talks, dancing, snowboarding or F18 catamaran sailing whenever he gets a chance. 🗣 Yonatan Karp-Rudin Yonatan Karp-Rudin is a Staff Engineer at Billie, building event-driven systems in Kotlin and Spring Boot. Off the clock, he plays with AI agents and builds random tooling, trying to hand off as much of his own workflow to a machine as he can. The rest of the time he's brewing mead or deep in a video game. **🗣 TBD**

Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration! This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. **New to electronics or curious about tinkering?** You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Worthington Park Library in the Olentangy Meeting Room.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** *Customize the IDE: Building Extensions for Visual Studio Code* Visual Studio Code is one of the most widely used development environments today, and much of its flexibility comes from its extension ecosystem. Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD

We've moved to guild.host Look for us there. https://guild.host/events/buckeye-cocoaheads-nscoders-tcbrk5

The Forge does have a full bar and kitchen. There is no cover charge but they do request all attendees to purchase a minimum of ~20 per person. Soft drink refills are 1 each. Please support our hosts so we can continue to provide great events for the group! The Forge has a large library of games available for us to enjoy. Hosts and regulars will also provide numerous popular games but please bring any games you would like to teach and/or play. Doors open at 6, and we expect gaming to be rolling by around 630. Please promptly end your games and clear out the space at 10pm when the bar closes. We encourage socializing but do not permit disruptive behavior of any kind. Thank you for your continued commitment to providing a fun and welcoming space to veteran, newbie, and rookie gamers in the Columbus area. Parking can sometimes fill esrly. There is additional parking lot behind the neighboring Mexican restaurant that is free and easy to walk from but it's a bit hidden.

Welcome to Casual Boardgames, where we enjoy classic tabletop games and social deduction games while bonding over good food, drinks, and great conversations. 
We started this group to meet new people and make new friends, and bonding over games in a relaxed atmosphere is a great way to do that. We currently meet near route 23 and Polaris Parkway, and this is close to areas like Powell, Lewis Center, Worthington, and parts of Westerville and Columbus. 
Feel free to bring your own games or play one of the many games our members bring. If you are inexperienced, we will help you learn. 
Here are just a few examples of the kind of games we play. 
Tabletop/board games: Splendor, Catan, Azul, Dominion, 7 Wonders… 
Social deduction games: Code Names, Chameleon, Werewords… 
IMPORTANT: 
1. While we love playing a variety of games and competing, we are not just about the games. We interact and talk while playing, and this leads to a lot of laughter and fun. If you just want to compete and focus solely on the game, then this is probably not the group you are looking for. 
2. Many people join groups like this and never (or rarely) show up after weeks or months. If you join and never really come, we will eventually remove you from the group as a courtesy to our members. Why? Because limiting group conversations (on the app) to regular members makes communication and planning much easier. Also, while it may be rare, it protects members from people who join because they are interested in following a person instead of having a real interest in our group. If you get removed, it is just because you haven’t come, and we follow this protocol as a courtesy to our regular game players.
