Financial Engineering

Back in August, we explored how Design Thinking can help us uncover and validate the right problems. But even when we agree on what to build, things often go wrong, not because of bad solutions, but because we don’t fully understand what the problem actually means in practice. In this session, we’ll build on that idea and focus on the next step: turning vague ideas into something concrete, shared, and testable. Using Example Mapping - a lightweight technique from Behaviour-Driven Development (BDD) - we’ll work in small groups to: * Break down a feature into rules, examples, and questions * Surface hidden assumptions and edge cases * Align on what the behaviour of a system should actually look like If the previous session was about finding the right problem, this one is about understanding it well enough to build it right. This is a hands-on workshop. Be prepared to participate fully and add to the energy of the room. Looking forward to seeing you there!

!!! Please note that this meetup will be held entirely in German only !!! Weil es bei den letzten Malen so schön war, treffen wir uns diesmal wieder im **CI Space auf der Bugenhagenstraße 9, 10551 Berlin** (https://maps.app.goo.gl/dXaYKm8fkhBsxk42A).

R. bereits ab 8:30 Uhr da, um vorab schonmal ein bisschen durchzustarten mit dem Netzwerken :)...

Die Teilnahme ist generell kostenlos und **nicht** an eine Mitgliedschaft gebunden. **Bitte beachten:** Unternehmer mit Multi-Level Marketing-Geschäftsmodellen schließen wir von unseren Veranstaltungen komplett aus, da wir hier die Erfahrung machen mussten, dass es dabei oft nur ums Verkaufen geht, und meistens kein echtes Interesse am Netzwerken und am Gegenüber existiert. **Weiterhin** stehen wir deshalb auch allen Arten des Provisionsgeschäfts (Finanzoptimierer, Immobilienmakler, Versicherungsvertreter, etc.) extrem kritisch gegenüber und gestatten diesen keine Teilnahme an unseren Events. Solltet ihr der Meinung sein, ihr fallt nicht in diese Kategorie, obwohl ihr in einer der genannten Branchen arbeitet, so sprecht uns bitte im Vorfeld an. Wir freuen uns darauf, auch **dich** persönlich kennenzulernen und dir bei der Entwicklung deines Geschäfts weiterzuhelfen!

**Coût de l’événement : € 0,50** On se rencontre mardi prochain pour discuter en français dans une ambiance amicale chez le café / resto Spreegold en Prenzlauer Berg, ou on a réservé une table (il faut demander du French Meetup). Le restaurant n'accepte pas les paiements en espèces. Merci et à bientôt! PS: Le coût de **€ 0,50** s'explique par le fait que par le passé, certains participants ont oublié de payer leurs consommations, laissant l'addition aux autres.

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.

In our last sprint, we established our cloud-native foundation by containerizing our agents and deploying them to Google Cloud Run. But manual deployments don't scale and require you to dig out the exact docker build and gcloud push commands from your shell history every time you tweak your agent’s prompt. **The Plan:** This session is about creating a **truly robust, repeatable deployment process**. We will wrap up our infrastructure setup by writing GitHub Actions that automatically build and push our agent containers to Google Cloud Artifact Registry on every commit. With a solid, "set-and-forget" pipeline in place, we'll shift focus back to agent behavior. We will build a simple orchestrator agent that uses the A2A protocol to dynamically delegate tasks to the worker agents living in the cloud. **This is a "Lab" session. We will:** * Automate for Robustness: Replace manual command-line wrangling with a GitHub Action workflow to build and push our Docker images to GCP on every push to main. * Build the Orchestrator: Develop a lightweight central agent designed to interpret a complex user prompt and route sub-tasks appropriately. * Live Multi-Agent Communication: Establish an active dialogue over the A2A protocol between your local orchestrator and your newly deployed cloud workers. **The Format** 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. This is a high-density micro-meetup limited to 6 seats. **What you'll build** By the end of the session, you'll have: * A Repeatable CI/CD Pipeline: A set-and-forget GitHub Action that handles the Docker build and Artifact Registry push automatically, ensuring consistent deployments without the hassle. * An Orchestrator Agent: A coordinator capable of breaking down requests and utilizing external agent tools. * A Live A2A Network: A functioning multi-agent setup where your orchestrator successfully communicates with and aggregates results from your cloud-hosted workers. **Schedule (Saturday, 10:00 - 13:00 CEST)** * 10:00: Quick round of introductions. * 10:15: Intro session: Robust CI/CD with GitHub Actions, Artifact Registry, and Orchestrator routing patterns. * 10:30: Build time: CI/CD automation & building the Orchestrator. * 12:00: Live demos + technical teardown. * 12:45: Wrap-up + takeaways. **Prerequisites** * Accounts: A Google Account (for GCP) and a GitHub Account (for Actions). * Laptop with dev setup: Docker and Git installed and working. * Access to an LLM API: (Gemini, Claude, OpenAI, etc.). * Mindset: This is a lab for engineers, not a tutorial. We learn by building, breaking, and iterating. **Logistics** * Location: We meet at my office in the Grunewald area near Martin-Luther-Krankenhaus. The exact address will be shared privately with attendees to maintain privacy. Capacity: Limited to 6 seats.

The full list of links will be published at [bitdevs.berlin](https://bitdevs.berlin) 1–2 days before the event — please review them in advance to get the most out of the discussion. **Important details:** * This event is highly technical — best suited for those with a solid grasp of Bitcoin internals. Curious newcomers are always very welcome, but expect in-depth conversations (see the former topics at [bitdevs.berlin](https://bitdevs.berlin)). * Chatham House Rule applies: you may share what was discussed, but not who said it. No livestream, no photos, no recordings. * The evening begins with food and networking; people often stay after the seminar to keep talking. **Co-hosted by:** * [Felix](https://x.com/FelixWeis) * [Freerk](https://x.com/freerko) * [Fabian](https://x.com/fjahr) For background on the idea of BitDevs Socratic Seminars, see [this article](https://bitcoinmagazine.com/articles/op-ed-want-to-learn-about-bitcoin-try-a-local-socratic-seminar).

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

Learn how seller finance and notes can create cash flow and new deal opportunities with 40-year investor Eddie Speed **FREE TICKET** 🎟️ https://www.eventbrite.com/e/how-to-structure-real-estate-deals-using-seller-finance-and-notes-tickets-1984826171509?aff=cicmeetupapp Most real estate investors only know one way to make money: Buy the property. Fix the property. Rent it or sell it. But there’s another side of real estate that can create cash flow, flexibility, and opportunity without only focusing on owning more property. At this month’s Columbus Investors Club, Tiffany and Josh High are sitting down with Eddie Speed - a real estate veteran with 40 years of experience who has closed more than 50,000 note deals. He has spent decades helping investors understand how to structure deals through seller finance and notes, and how to think more like the bank instead of just the buyer. This will be a practical conversation around a part of real estate most people have heard about, but very few truly understand. If you’ve ever wanted to know how to create more opportunities in deals, generate cash flow in a different way, or understand how seller finance actually works in the real world, this is a night you want to be in the room for. You’ll walk away thinking about deals differently, seeing new possibilities, and understanding how creative structuring can open doors that traditional investing alone can’t. **What You’ll Learn** * How seller finance works in real estate deals * How notes fit into real estate and create opportunity * How to structure deals more creatively * How investors generate cash flow by focusing on the payment * How to think like the bank instead of only focusing on owning the property * How this strategy can create flexibility in today’s market **Open Q&A - Ask Eddie Anything About** * Seller finance and how to use it in real deals * How notes work in a practical, beginner-friendly way * Creating cash flow without only relying on rentals * Structuring deals that others might miss * How experienced investors think differently about financing * Common mistakes investors make when they only focus on the property **Why You Should Be in the Room** Because the investors who win in the long run know how to do more than just buy houses. They know how to structure.They know how to create terms.They know how to see opportunities other people miss. This is the kind of conversation that can expand the way you think about real estate entirely. Come ready to learn, ask questions, take notes, and connect with people who are serious about growing in this business. **Reserve your free seat now - and be part of the conversation.** Grab your spot here ➡️ https://www.eventbrite.com/e/how-to-structure-real-estate-deals-using-seller-finance-and-notes-tickets-1984826171509?aff=cicmeetupapp

The market changed—and most investors are still operating like it didn't. Deals that used to work don't. Buyers want different things. And a lot of what's being taught right now is outdated or just wrong. And, since 2011, it's been our job to make sure that our members are armed with the most up-to-date, real-world strategies for building wealth in Central Ohio real estate… …so our mission with this meeting (and every meeting) is to give you the no-hype, warts-and-all info you need to succeed. First, Wholesaling 101—a clear, real-world look at how wholesaling actually works today, what to pay, and how to stay out of trouble. Then, Creative Deal Autopsies—real investors breaking down real deals with real numbers, real conversations, and real outcomes. You'll also get the chance to put the presenters in the hot seat and ask any and every question you have about how they did their deals. You'll learn: 1. What wholesaling actually is 2. How to calculate real offers 3. Where deals are coming from now 4. What buyers want 5. How creative deals are structured 6. What contracts and terms are used 7. What can go wrong—and how to avoid it **Agenda:** 5:00–6:00: Free Light Dinner and Networking 6:00: Earlybird Meeting – Wholesaling 101 7:00: Buy-Sell-Trade (members only) 7:30: Creative Deal Autopsies Members: Free First-time guests: Free Non-members: $35 (or join for $30 instead) Remember, to actually reserve your seat, you have to go **[HERE](https://www.coreerocks.com/Events.aspx?ID=IN-PERSON-in-Columbus-Creative-Deal-Autopsies-Wholesaling-101-14-4-7-2026)** and register on our website!
