Join us for the LFDT Berlin Monthly Meetup, a relaxed gathering for those involved in or curious about Linux Foundation Decentralized Trust (LFDT). This is a space for open discussions, knowledge sharing, and networking among professionals working on decentralized technologies. Each month, we come together to share projects, discuss challenges, and exchange ideas on navigating the LFDT ecosystem. Whether you're looking for insights, solutions, or just good company, you'll find a supportive community eager to collaborate and help. There’s no formal agenda—just organic discussions on the latest developments, real-world applications, and ways to make decentralized trust more impactful. Whether you’re an industry expert or just starting out, you’re welcome to join us, contribute, or just listen in. Come grab a drink, meet like-minded people, and let’s build the future of decentralized trust together!

This is an [in-person communication lab](https://www.presentation-school.com/berlin-presentation-lab) that helps professionals speak clearly and confidently under pressure using proven methods. Most people don’t struggle because they don’t practice enough. They struggle because they practice without the right principles. This session focuses on deliberate, guided practice informed by performance psychology, neuroscience, and modern communication training. **What You Will Do** * Learn one science-based communication principle that improves real-world performance. * Train that principle in structured speaking exercises designed for skill development. * Receive clear, professional feedback you can apply immediately. Practice and feedback are guided by experienced communication professionals who work with executives and senior professionals. This is not peer-to-peer feedback or open discussion. **Who Should Attend?** * Non-native English speakers * Professionals who present, lead meetings, or speak up at work * Anyone who overthinks, freezes, or loses clarity under pressure * People who want structured improvement, not just repetition No prior experience is required. **What This is NOT** * A lecture. * A motivational talk. * A public performance. * Unstructured open practice. * Peer-led feedback or opinion-based critique. **Before The Session** Before the session, participants complete a short preparation form to clarify their goals and common communication challenges. This helps ensure the practice and feedback during the lab are as relevant and effective as possible. **Optional:** Participants may submit a short video (1–2 minutes) or written questions. This is optional and used to personalise focus areas and examples during the session. No individual coaching is provided. **After the Session** Participants receive a short follow-up pack with key takeaways, practical drills, a reflection question, and guidance on next steps. **Practical Information** Language: English Duration: 2 hours Format: In-person, structured group lab Address: Chausseestraße 86, 10115 Berlin Healthy snacks and water provided. Price: €25 per session If you are looking for a professional, practical way to improve how you communicate and want to train using principles that actually lead to results, this lab is a good place to start.

Are you keeping up with how fast AI is changing the way we work? We are in the midst of understanding how AI is reshaping our roles, workflows, and what is possible in product development. The pace of change is rapid, and many managers are actively experimenting and learning as they go. We’ve invited two experienced product practitioners to share their hands on experience and learnings: **Daniel** will focus on how AI can be used to increase personal leverage and productivity as a product manager. **Ruslan** will share his experience with turning AI prototypes and real products. This event is designed for hands-on product managers and product builders who want to improve their workflows and rethink how products are built within their organizations. **Agenda** 18:15 – Doors open for snacks, drinks, and networking 19:00 – Welcome from ProductTank Berlin 19:10 – Demystifying AI: A Productivity Playbook for Product Managers, Daniel Zherenkov 19:40 – Building with AI: How Smart Prototypes Become Real Products, Ruslan Vorobev 20:10 – Networking 21:30 – Event ends **Please note:** * **Please bring your IDs as you’ll need it when entering the venue.** * The event is RSVP only: to enter, you must RSVP here on Meetup. * We'd like to capture the event with photographs for promotional purposes, such as sharing on LinkedIn after the event. If you have any concerns or preferences regarding this, please feel free to let us know beforehand. **Demystifying AI: A Productivity Playbook for Product Managers, Daniel Zherenkov** To harness the power of AI, you first need to understand it. Join this session to strip away the FONO tropes from LinkedIn and understand the reality of today's AI capabilities. We will explore practical frameworks for integrating AI into the product management daily life, empowering you to make better decisions, streamline workflows, and build superior products. About the speaker: Daniel, ML/AI Product Manager at Delivery Hero with 8+ years of experience in creating ML and AI products, will explain what AI actually is and how to squeeze the maximum efficiency from it based on the real examples that could be reproduced by anyone. **Building with AI: How Smart Prototypes Become Real Products, Ruslan Vorobev** The talk looks at how AI can turn quick prototypes into real, valuable products. Ruslan shares practical lessons from using tools like Lovable, GPT, and internal automations to move from idea validation to production-ready solutions. The focus is on finding where AI truly adds value, whether through lightweight assistants or deeper integrations, and where it’s better left out. About the speaker: Ruslan Vorobev is Head of Product with a strong focus on innovation and AI-driven solutions. He has overseen product and business development across sustainability, circular economy, and manufacturing domains, helping scale digital products from early prototypes to market-ready solutions. His work combines hands-on experimentation with practical automation to turn ideas into tangible impact.

Ditch the old book club, where everyone has to read the same book...this is better! It works like this: Bring your own book. Come chat, have some tea or coffee, get to know your neighbors. Then we quietly read together, side by side, for about one hour, each one reading their own book, and afterwards we talk with each other about what we are reading. The usual agenda: - Arrival and introduction (~20 minutes) - ⁠Silent reading (~1 hour) - ⁠Discussion (~30-40 minutes) - ⁠Join us for a bite at a local restaurant afterwards, if you like! You may read in any language, you may read any book. We are a group of international residents of Berlin from many different countries, of all ages, and we converse in English. We welcome you! No registration needed – the event is donation based. All funds support the Offenes Wohnzimmer.

Whether you've never done improv before, or you've done it for so long you knew Del Close on a personal level, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup** for some fun and games! The idea behind improv is to create entire scenes from scratch based on a suggestion from the audience. This can be done in game form, like *Whose Line Is It Anyway*, *ComedySportz*, or *Wild 'n Out*; it could also be done to tell stories, like *Middleditch and Schwartz*. Our meetup, which is central Ohio's longest running (and free!) weekly comedy event, brings the games (and occasionally different forms) for you to play in a safe, supportive, and compassionate environment. Not only is it a lot of fun, but you get to work on thinking faster on your feet, plus it's an excellent way to meet new people and make friendships that'll last a lifetime! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "Yes, And" that you'll have fun!
