Welcome to Sunday Tech Coffee. This is a **networking** event for those in the tech industry in Berlin. We are usually inside and to the right. Ask the barista/bartender if you can't find us.

On stage, five languages coexist — English, German, Italian, Spanish & French — within a shared narrative. Clarity doesn’t come by chance: the performance is carefully conceived with a system of clarifications, contextual translations and narrative tools that allow the audience to follow the story, regardless of the languages they speak. There are no subtitles and no simplifications. Understanding emerges through structure, relationships and emotional dynamics. Created in Berlin in collaboration with improvisation schools working in their own languages, Berlino Babel reflects a city where many languages meet — and still manage to listen to each other. Tickets here: https://www.yesticket.org/event/en/berlino-babel-multilingual-impro-show-16-05-26/

Join this Professional Communication session — to sharpen the skills for architectural pitches, elevator pitches, interviews. This time we meet in the Monbijou park. 💡 How it works The event is split into two parts: 1. **Communication (10 minute rounds)** – One participant answers a round of design and behavioral questions. Each other participant gets to ask him one question. 2. **Feedback Round** – The group provides feedback on communication, structure, and clarity. Constructive criticism is encouraged. 💡You will be asked: * **Light design problems** (high-level reasoning, not code) * **Behavioral questions** (“Tell me about yourself”, “Describe a challenge you faced...”) No need to prepare anything in advance — just bring curiosity and an open mind. 💡Note: location is the entrance to Monbijou park

Hello Gophers, Welcome back for another year of Go talks and networking! Would your company like to host our meetup? Let us know! If you'd like to give a talk - submit your proposals here: http://goo.gl/forms/54YvJT223F All talk formats work: short talks (5-10 min) as well as regular length (25 min). If you have more ideas - talk to us at the Gophers slack: https://invite.slack.gobridge.org/ in the #berlin channel, and follow us on twitter: https://twitter.com/gdgberlingo **Speakers**: *Simon Schulte* is a Tech Lead with nearly a decade of experience building scalable backend systems across fast-paced product companies. With a background in business informatics and a passion for Golang, cloud infrastructure, and DevOps, he has spent his career solving complex engineering challenges. He is particularly excited about leveraging AI and LLM workflows to eliminate the tedious, repetitive work that slows developers down — think tech debt, boilerplate, and documentation — so engineers can spend their energy on what actually moves the needle. For Simon, AI isn't about replacing developers; it's about giving them back their time. *Daniel Peralta Madriz* is a backend engineer from Costa Rica with around 6 years of experience working with Golang, although, sadly, he's been spending most of his time lately working with Node.js :(. He is interested in distributed systems, scalability, and developer experience, and is currently experimenting with how to leverage LLMs to safely and autonomously execute repetitive tasks. *Michael Morgen* is a Platform/infra engineer by day, runtime and network optimizations by night. Join in person at: **Talon.One** Talon.One is the incentives engine behind 300 of the world’s most-loved brands, unifying loyalty and promotions on a single flexible platform.

Practical AI for Power BI Developers A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective. This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly. Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.
