📅 **Week 4 Focus: Calling LLM via API** Each 7-week cycle focuses on a small, well-defined part of a larger system—and over time, these cycles build toward a complete, real-world project Feel free to join at any week and we will catch you up. There is no need to be at the beginning of the cohort to build. Complete beginners welcomed! 📌 By the End of a Full Cycle, You should Have 🎯 A working project in your own GitHub repo 🎯 A small but real portfolio piece you can demo or write about 🧠 **Current Project** This cycle’s shared project is an **image-based knowledge extraction system**. In Week 3, we trained a deep learning object detection model (YOLO) and learned how modern computer vision models are built. **In Week 4** we will try **LLM-based image understanding via APIs** to extract structured information from images and comparing this approach with traditional computer vision and building your own deep learning methods. * \*\*\* **👋 Who Is This For?** 🔹 Beginners who learn best by doing — no prior experience needed 🔹 Career switchers from product, engineering, design, marketing, or other fields who want to break into data 🔹 Analysts, engineers, and PMs looking to sharpen their skills or build real-world projects 🔹 Data professionals who want a creative playground outside of work 🔹 Anyone with big questions and a love for learning through experimentation \*\*\* **BUILD. LEARN. EXPERIMENT. OVER COFFEE.** Come hang out, meet like-minded people, and work on something fun. 📍 Based in Berlin – in-person meetups only (for now!) 💻 Laptops + ☕ highly encouraged Join our Discord → [https://discord.gg/dPnmzcCP8w](https://discord.gg/dPnmzcCP8w) Check out our program resources: [Google Drive](https://drive.google.com/drive/folders/15DmZqD4bLBk2vU4zpvh1HiB3_5n09v-q?usp=sharing) \*\*\* ✨ Who’s Hosting? I’m Lindsey, a senior data scientist working on AI, causal inference, and data products. I’ve built models for fraud detection, uplift modeling, and LLM-based systems. I am always open to suggestion for different format for this meetup.

**Agentic AI Engineering Lab (Tech Event, Sprint #1)** **\- Build a Production\-Ready MCP Server** **Move from prompting to architecting** The Model Context Protocol (MCP) is an emerging open standard for connecting AI apps/agents to real tools and data sources. This session is not a talk — it’s a hands-on lab where we build MCP servers that can be tested immediately with an MCP-capable client (e.g., Claude Desktop / your preferred agent setup). **The Format** We are planning a series of agentic ai tech meetings for deep building. This event may be attended alone or be seen as part / sprint of the event series with upcoming events building on top of what we build here. This is a high-density micro-meetup limited to 6 seats. We prioritize builders: bring your laptop, ship code, and be ready to 'build and break' alongside other devs and engineers. **Future Sessions building on top may focus on ...** RAG systems, advanced MCP features, A2A, multi-agent workflows, production deployment Patterns or whatever we feel nice to build next. (We run our sessions like an anthology series: **Every meetup is a standalone sprint.** While we often build on previous results, each session provides a complete experience and remains fully accessible to first-time attendees.) **What you'll build** After a quick alignment on the technical scope, the floor is yours: build your solution using the stack and tools that fit your workflow. We provide the framework; you provide the execution. By the end, you’ll have a working MCP server (Python or TypeScript) with at least one real tool/resource, tested end-to-end. **Ideas: Choose one track (or bring own idea if it fits the scope)** **For Beginners (Foundational)** * Personal knowledge server (local files/notes) * Weather / external API integration * GitHub issues helper **Intermediate** * SQLite query interface * Slack/Discord notification tool * CSV/Excel analyzer **Advanced** * Multi-API aggregator (e.g., calendar + weather + tasks) * Document processor (PDF/DOCX parsing) * Lightweight system monitoring/control **Schedule (Saturaday, 10:00 - 15:00 CET)** * **10:00–10:30 — Foundations + Live Demo** Quick run through general MCP architecture (hosts/clients/servers), core primitives (tools/resources/prompts), basic patterns in order to get everybody on the same page. * **10:30–11:00 — Environment Sync** We wanna make sure everyone can run a “Hello World” MCP server (Python or TypeScript). * **11:00–12:45 — Build Sprint (Lab Time)** Implement your server + first tool/resource. Pair-debugging encouraged. * **12:45–13:00 — Break (Pizza/Snacks)** * **13:00–13:30 — Test & Iterate** Use MCP Inspector / your client to test, fix edge cases, tighten tool contracts. * **13:30–15:00 — Demos + Technical Teardown** Quick demos, what broke, what worked, and what we’ll harden in the next sprint. **Prerequisites (Please Read)** * You’re comfortable shipping small things in your preferred dev language and tools (e.g. Python, TypeScript/Node.js). * **Bring your laptop** + basic dev setup (Git, package manager). * Have access to an LLM client / API (Claude/OpenAI/etc.). * This is a lab for engineers, not a tutorial. We solve architectural problems together, but you are the master of your own dev environment. * **Mindset:** Build, Break & Iterate — broken code is welcome, passivity isn’t. **Logistics** * **Location:** Our private boardroom in the Grunewald area (near Martin-Luther Hospital). The exact address will be shared after RSVP. * **Capacity:** 6 seats (first come, first served; deposit required) **Commitment Deposit and No-Show / Late-Show** This meetup is strictly non-profit. To respect everyone’s time and ensure all 6 seats are utilized by committed builders, a €15 deposit is required. * **The Deal:** The deposit covers high-quality pizza, snacks, and drinks. Any surplus will be refunded to you via your original payment method after the event. * **Punctuality is Key:** We start at **10:00 sharp** with the technical foundations (door open from 09:45). To protect the group’s focus, late arrivals or no-shows will not be eligible for a refund. Their deposit will be fully contributed to the community's pizza & snack fund. * **Cancellations:** No refunds for cancellations within 24 hours of the start time.

**URGENT ACTION SUMMIT 2** \- “What is happening in Amerika?” Sat 14 Feb 15-21:00 @Baumhaus Berlin **This is an event for those who feel a sense of urgency or desperation to get society to act in solidarity faster to address critical issues like climate change and the rise of fascism.** 15:00 doors open and open networking 16:00 interactive talk 16:30 Q & A 17:00 break and open networking 18:00 workshop - developing viral interventions 19:00 group feedback 19:30 quick pitches 20:00 open networking 22:00 end The first Summit took place in June of 2024 and resulted in 2 teams of people who developed a short video prototype that describes the nature of these wicked problems and an online curated platform to connect a trusted network of local change makers in Berlin and beyond. • video - https://www.youtube.com/watch?v=Z9ml3AEzZhE • platform - https://ourworld.solutions/ During this interactive talk, discussion and workshop Scott Bolden, founder of Baumhaus Berlin will build on the work from Urgent Action Summit 1 and address the questions: 1 - “**What is happening in Amerika?**” & 2 - “**What kinds of meaningful and practical responses can we come up with in Berlin that can make a positive difference?"** The story of America is a complex one but can be broken down into a few simple fundamental concepts that explain why the state of things are the way they are today. We will explore why it makes sense that Trump and his kind have risen to power and how we can contribute to his fall by doing the things we already love to do. We will also make the connection to the common roots of authoritarianism and climate change as well as sharing strategies to address both. Making a difference in the world doesn’t have to be lonely hard work that one has to sacrifice everything for. The objective of this summit is to identify some common ground that can form the basis for a movement of authentic and resonant solidarity right here in Berlin; one that has the potential to spread. **How can we collectively have fun getting good things done?** The ideas, connections and synergies that are shared during this event will provide a basis for developing program and interventions for the next Emergent Berlin festival happening in Fall 2026 (check out Emergent Berlin 2025). Participants are encouraged to share their findings on the Emergent Berlin instagram page use it as a living working document to help realized some of the ideas that get developed. https://www.emergentberlin2025.de/ Entrance: open donation **support Baumhaus crowdfunding campaign** ( https://www.goodcrowd.org/saving-das-baumhaus ) feel free to bring drinks and snacks to share, there will also be some food and drinks on a donation basis Baumhaus Berlin Gerichtstr 23 VH Eg 13347 Berlin \* Bonus - improv theme song for this event https://soundcloud.com/user-164945673/urgent-action-summit-2-call-to

Hey everyone! I’m organising a co-working + socialising session for all of us who like to work on something (e.g. our own project, freelance or remote work) but don't feel like sitting alone at home. 🙂 To ensure that we have both **socialising** AND **working**, we will be using the so called “Pomodoro” technique: **50min of deep work** (silent), followed by **10min of break** to socialise. Then repeat! If you get into flow, you're also welcome to skip the breaks. It’s an effective way to stay focused - you can read more about it [here](https://en.wikipedia.org/wiki/Pomodoro_Technique). Anyone from any background is welcome, whatever project you are working on or whatever is your personal background. I (the host) speak English and German, so either is fine :-) ——————————————————- AGENDA: * **15min Intro** * Get to know everyone, talk about what you will work on today * **Pomodoro Session** (3x) - *Each Pomodoro session consists* *of...* * ...**50min** of uninterrupted “deep work” (no talking, no interruptions, no phones) * ...**10min** of break: share your progress with others, talk about what you are stuck on etc. * Repeat * Conclude and celebrate your progress Share your progress, socialise and get to know others 😊 ———— We'll be at the Social Hub Berlin (they have a food menu in case you get hungry). The structured part will end at 2:30pm, but you're welcome to stay longer, go for lunch together, or leave earlier. See you there 🩵 **\*\*We'll reserve the long table. Please update your RSVP in advance if you can't attend!\*\***

This is a free, in-person meeting on the subject of betrayals, losses and how to get over them so you can build lasting relationships. Burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life. We look forward to having you join us! This class is sponsored by the Dianetics & Scientology Life Improvement Center of Central Ohio.
