In many organizations, APIs are treated as technical contracts — neat documentation of endpoints and payloads. But what if APIs could become something more: living expressions of the business domain itself? This talk examines how Domain-Driven Design (DDD) and modern API craftsmanship converge to establish a shared language between people and systems. We’ll walk through how techniques like Domain Storytelling, Event Storming, and Context Mapping can lead directly into OpenAPI and AsyncAPI specifications that reflect real domain intent — not just data structures. **How can LLM help?** Along the way, we’ll see how Large Language Models (LLMs) can amplify human creativity — helping teams turn visual domain artifacts into executable API contracts while preserving intent and nuance. Instead of replacing design thinking, AI becomes a collaborator in the craftsmanship process. Through practical examples, we’ll explore how bounded contexts define API boundaries, how ubiquitous language shapes resource and event models, and how contract-first design enables safe, evolutionary change. By the end, you’ll see APIs not merely as integration points, but as living domain boundaries to align architecture, business, and shared understanding. **About the speaker** [Annegret](https://www.linkedin.com/in/dr-annegret-junker-141a99a4/) is Chief Software Architect at codecentric AG in Germany. She has worked in software development for over 30 years. She worked in quite different roles and domains. She is especially interested in DDD, microservices, and everything else. She is working on a large integration project and defines APIs for partners. **The Sponsor** This time, the location, food, and drinks are sponsored by [TechTalk](https://techtalk.at/).

How honest are we really — with others and with ourselves? Is there something as too much honesty? What are the pros and cons of being honest? How honest do you think you are?

Expect a safe and welcoming atmosphere, light humor, practical communication tools, and space for both speaking and silent reflection.

Hi Running fellows, Whether you’re a walker, new to running, a semi-pro, a marathonist or a sprint star - if you want to start your weekend in an active way and enjoy the outdoors in lovely surroundings with a fun, international and multilingual group of people, you are welcome to join us! Every Saturday at 9:30 am, we meet, we run, in the magnificent Schönbrunn park, and then we go for breakfast. Want to discuss politics or the best recipes for banana pancakes? Not a problem. Not feeling social? Tune out with your earbuds - we can talk over breakfast. We are casual. You can be too. What to expect: Start by meeting Adrian, Ali, Liz, Paul and Sonia on-time at 9:30am outside the Schönbrunn U-Bahn stop (exit Grünbergstraße). (Coordinates: 48.1858130, 16.3200640) From there, we walk to the side park entrance where the “running” part begins. The important thing is that you run at your own pace. Typically, small groups of people will run at the same pace as you, so you never have to walk/run alone :) We finish one hour later, at about 10:40am, reconvening just inside the Hietzinger Tor exit. (Coordinates: 48.1858825, 16.3032647). From there, we’re off to breakfast! Breakfast Details: Anker bakery opposite the U4 Hietzing station and depending on the weather, grab something for a picnic in Schönbrunn park, or hang out in the bakery. If you missed us earlier, you can always go there around 10:45. We are a fun group of runners who don’t take things too seriously. We meet, chat, RUN, stretch, chat, EAT and we hang out over a beer every now and then. It's that easy. Please join us for breakfast after the run! The more the merrier. Typically we are 10-30 people, as not everyone who comes signs up on meetup. Important disclaimer: Please only run as much as you feel you can, considering the temperature, weather conditions, your own fitness etc... run and walk at your own pace as the organizers do not assume any liability for any injuries or health issues. Sonia, Adrian, Ali, Paul and Liz

This practical webinar is designed for self-employed professionals and small business owners in Austria who want to become easier to find, easier to trust, and easier to choose - both on Google and in AI-driven search. Save your spot: [https://www.self-employed.at/event-details-registration/boost-your-google-ai-visibility-practical-visibility-steps-you-can-implement-tomorrow](https://www.self-employed.at/event-details-registration/boost-your-google-ai-visibility-practical-visibility-steps-you-can-implement-tomorrow) About the event Google is no longer the only place people search for solutions. Today, your potential customers are also asking tools like ChatGPT, Perplexity, Gemini, and other AI systems for recommendations. The question is: Will your business show up when they are looking? This practical webinar is designed for self-employed professionals and small business owners in Austria who want to become easier to find, easier to trust, and easier to choose — both on Google and in AI-driven search. You will leave with clear, realistic actions you can start implementing the next day. What this webinar is about: Many businesses want quick visibility. They ask: “How do I get to number one on Google?” “How do I appear in ChatGPT?” “How do I make my content perform better?” These are valid questions, but they often focus on speed instead of substance. The businesses that win long term are not the ones chasing shortcuts. They are the ones that clearly understand their audience, build trust consistently, and position themselves in the places where buying decisions are made. This webinar will show you how to start doing exactly that. In this session, you will learn: How Google and AI search are changing the way people discover businesses Why being visible is no longer just about rankings, but also about trust and authority What makes a business more likely to be found, understood, and recommended online How to identify the search terms, questions, and topics your audience actually cares about How to improve your website content so it speaks to both people and search systems What practical steps you can take tomorrow to strengthen your online visibility How to think long term instead of chasing short-term tactics Who this is for: This webinar is for you if you are: A freelancer, consultant, coach, service provider, or small business owner Trying to attract more consistent inquiries through your website Interested in SEO, Google visibility, and AI search, but unsure where to start Tired of random marketing tips You do not need advanced technical knowledge. The session is practical, accessible, and focused on actions you can realistically implement. Why this matters now: Search behavior is changing. People still use Google, but they are also using AI tools to compare options, understand services, and make buying decisions. That means your business needs more than a few keywords on a website. You need clarity. You need content that answers real customer questions. You need trust signals. You need a presence that helps both humans and search systems understand who you are, what you do, and why you are relevant. This is especially important for self-employed professionals, because trust is often the deciding factor before someone reaches out. About the speaker: The webinar is led by [Rilwan Mogaji ](https://www.linkedin.com/in/rilwan-mogaji-digital/)\- the co\-founder of [Mogaji Digital Communications](https://seo-agenturwien.at/en/), an SEO agency based in Vienna. For more than five years, he has helped companies become more visible through Google and, increasingly, through AI systems like ChatGPT — with the goal of generating new customers consistently and predictably. His work has been featured in outlets such as MeinBezirk, Wiener Wirtschaftszeitung, Radio Afrika, and Leadersnet. He also publishes industry-related articles on platforms such as [unternehmer.de](http://unternehmer.de/) and [designenlassen.de](http://designenlassen.de/). His mission is to help companies move away from short-term marketing tricks and toward long-term positioning built on clarity, consistency, trust, and a genuine understanding of their audience. You will walk away with: A clearer understanding of how Google and AI visibility work A practical checklist of improvements you can make to your online presence Ideas for content that directly answers your audience’s real questions A better understanding of how to build trust through your website and digital presence A long-term mindset for attracting more relevant customers online Event details: Date: June 25 Time: 17:00 Location: Online via Zoom Duration: 1.5–2 hours Format: Live webinar with practical examples and implementation-focused guidance Save your spot: [https://www.self-employed.at/event-details-registration/boost-your-google-ai-visibility-practical-visibility-steps-you-can-implement-tomorrow](https://www.self-employed.at/event-details-registration/boost-your-google-ai-visibility-practical-visibility-steps-you-can-implement-tomorrow)
