Zalando is graciously hosting us for our first Meetup in 2026. And we are doing it a bit different: we have two rooms, and two talks in parallel. This gives you the opportunity to choose between two talks, for a total of four talks. This year, we’re especially happy to welcome Amazon Web Services as the food sponsor for our meet-up. Thanks to their support, our community can enjoy great conversations over great food — making the evening not only insightful, but also delicious. Meet the AWS experts Sikandra Chaudhary, Daria Aleshkova, and Narendra Tawar. Narendra will be delivering a talk on PostgreSQL and AI, sharing practical insights and real-world experience. We truly appreciate AWS’s commitment to supporting local tech communities and helping us create a warm, welcoming atmosphere for everyone. **PLEASE BRING YOUR PHOTO ID** **USE THE MAIN ENTRANCE TO BHW ON THE SIDE OF UBER ARENA** **Agenda** Two sessions run in parallel in rooms codenamed "Auditorium" and "Festival" **18:30** \- doors open: registration\, networking\, and drinks **19:00 - 19:05** Auditorium, "Event intro" by Sergey Dudoladov, Senior Database Engineer in Zalando. **Auditorium: Track A** **19:10 - 19:55** "How we made WarehousePG Open Source (again)" by Andreas 'ads' Scherbaum, a WarehousePG Principal Engineer at EDB and a Founding Member of PostgreSQL Europe **19:55 - 20:15** Networking, Q&A, and pizza **20:15 - 21:00** "From 20 seconds to sub-second: Speeding up CloudNativePG wake-ups" by Tudor Golubenco, CTO of Xata **Festival: Track B** **19:10 - 19:55** "The Role of PostgreSQL in the AI World" by Narendra Tawar, Sr Database Specialist SA, AWS **19:55 - 20:15** Networking, Q&A, and pizza **20:15 - 21:00** "Modernizing Postgres Communication with Hackorum", by Kai Wagner, Percona **21:00 - 22:00 Networking, Q&A, and pizza** **22:00 - The End** **Abstracts** **How we made WarehousePG Open Source (again)** WarehousePG is an Open Source fork of Greenplum Database, which by itself is a fork of PostgreSQL. The project was born after the upstream project was made closed source. This talk gives a quick overview of the history of both projects, which already spans more than two decades. We then dive into the reasons for creating a fork, and all the stumbling stones we had to pass in order to make this project open source again. We also talk about the challenges of CLAs (Contributor License Agreements) and what implications the PostgreSQL and Apache Licenses have for the project. Speaker: Andreas 'ads' Scherbaum **The Role of PostgreSQL in the AI World** As artificial intelligence (AI) continues to revolutionize industries, the need for robust, scalable, and efficient data management solutions has never been greater. PostgreSQL, with its extensibility, performance, and advanced data capabilities, plays a crucial role in enabling AI-driven applications. This talk explores how PostgreSQL supports AI workloads, from managing vast datasets and integrating with machine learning frameworks to leveraging extensions like PostgreSQL ML, TimescaleDB, and JSONB for AI-ready storage and querying. Attendees will gain insights into best practices for using PostgreSQL in AI pipelines, optimizing performance for AI inference, and harnessing the power of open-source innovation to drive intelligent decision-making. Whether you're a data engineer, AI researcher, or PostgreSQL enthusiast, this session will showcase why PostgreSQL is an essential component in the AI ecosystem. **From 20 seconds to sub-second: Speeding up CloudNativePG wake-ups** CloudNativePG (CNPG) is a popular and battle-tested operator for running Postgres on top of Kubernetes. At Xata, we’ve been using CNPG and extending it in several different directions. One of them is implementing a scale-to-zero plugin: clusters hibernate when inactive and they wake up automatically when new connections are created. After adding scale-to-zero, we’ve faced the challenge that the CNPG wake-up from hibernation is rather slow.This is an optimization story about how we reduced the wake-up times from 20+ seconds to under one second. Speaker: Tudor Golubenco **Modernizing Postgres Communication with Hackorum** In 2026, the debate over whether mailing lists are still "state of the art" continues to divide developers. While some view them as relics, we cannot neglect the unique benefits of their decentralized, archival nature. Rather than fighting over platforms or ignoring the friction, Hackorum asks a simpler question: Why not just improve the user experience? Hackorum transforms the daunting mailing list "firehose" into a modern, forum-style interface without breaking the underlying email culture. It is designed to lower the barrier for new contributors while providing power tools for veterans: Seamless Integration: Real-time sync between mailing lists and daily sync of the Commitfest status. Modern UX: Per-message read tracking, tagging, and contributor profiles. Enhanced Coordination: Shared notes and mentions to streamline complex reviews. We have to stay open minded and willing to expand our horizon and as such Hackorum is rapidly evolving. While our roots are in development, we are currently expanding to include broader mailing lists like -general and -docs. Our goal is to make the entire Postgres ecosystem more accessible and usable for everyone. Join us for a demo of the latest updates and help us shape the future of Postgres communication. Speaker: Kai Wagner **About the speakers** **Andreas Scherbaum** has been working with PostgreSQL since 1997. He is involved in several PostgreSQL related community projects, member of the Board of Directors of the European PostgreSQL User Group and also wrote a PostgreSQL book (in German). Since 2011 he was working for EMC/Greenplum/Pivotal and tackled very big databases. Until 2024 he was doing the same - but with maybe even more and bigger databases - for Adjust GmbH in Berlin. Now he's working at EDB as WarehousePG Principal Engineer and is helping customers with even larger databases. **Tudor Golubenco** is the CTO of Xata, a Postgres platform with branches and zero-downtime, reversible schema changes. Before Xata, Tudor worked as a tech lead at companies like Elastic and Oracle. **Narendra Tawar** \- Sr Database Specialist SA I am accomplished database professional with 21 years of comprehensive experience across Oracle, PostgreSQL, Microsoft SQL Server, and MySQL environments, with specialised PostgreSQL expertise since a decade. Currently serving as a Senior Data Migration Specialist at AWS, I architect and execute complex enterprise migration strategies while actively expanding into Generative AI technologies to enhance migration efficiency and optimize data workflows. My core competencies include database architecture, performance optimization, migration planning, and cross-platform data integration, combining decades of hands-on experience with modern cloud methodologies to deliver scalable, reliable data solutions that bridge traditional database principles with emerging AI capabilities. **Kai Wagner** \- I’m Kai\, a Senior Engineering Manager at Percona with almost two decades of "bleeding" open source in my DNA\. From the Linux Kernel and Ceph at SUSE to leading PostgreSQL development today\, my career is built on a foundation of transparent communication and community\-driven innovation\. In my free time\, I'm a handball\, agility and movement coach for various ages and teams\, next to spending time with the family and on the house\. **Note** We will again take notes who signs up and does not show up. This information will be used to provide seats to others at future events. Plain and simple: please only sign up if you plan to attend.

Ready to flex your architectural muscles… with a new twist? Join us for our first **AI-Enabled Architectural Kata**, where we'll tackle a real design challenge together, using generative AI as a collaborator in the architectural process. Small teams will work through a complex scenario, but this time each team gets a unique **AI collaboration role** that shapes how they interact with AI during the session. Expect lively debate, creative solutions, plus an honest reflection on where AI helps and where human judgement still reigns supreme. **Mark your calendars for Thu, Mar 5,** and join us at **Thoughtworks Event Space** for an engaging evening dedicated to software design and architecture. Whether you're a seasoned architect, an AI-curious developer, or just passionate about software design, this meetup is the perfect platform to share, learn, experiment with new ideas and meet passionate people. **Event Schedule** * **18:15** – Doors open for snacks, drinks, and socialization * **18:45** – Introduction * **19:00** – **AI-Enabled Architecture Kata**: Small teams' work session * **20:30** – Presentations by teams **❓ What is an Architectural Kata?** Inspired by the concept of “Code Kata,” Architectural Katas are exercises that allow architects to practice their skills in a real-world scenario. It's about honing our craft in software design through practical, hands-on challenges in small groups. Read more about Architectural Katas on [Neal Ford](https://nealford.com/katas/about.html)'s website or on the [original Katas site](https://www.architecturalkatas.com/) by Ted Neward. **What makes this one AI-Enabled?** Building on the classic Architectural Kata format, this edition adds a new dimension: **AI as a team member**. Each team receives a unique role card that defines how they collaborate with AI during the session. The goal isn't to see who can prompt the best. It's to explore together how AI changes the way we think about, discuss, and communicate software architecture. **What to bring** Please have access to at least one AI tool on your phone or laptop (Claude, ChatGPT, Gemini, or similar). We'll provide a short prompting cheat sheet for architectural AI collaboration to get you started. No prior experience with AI for architecture work is needed! **Venue** **Thoughtworks Event Space**, Revaler Str. 31, 10245 Berlin *(Please note that this is a different entrance from the Thoughtworks office located at Revaler Str. 29)* **Sponsored by Thoughtworks** A big shout-out to [Thoughtworks](https://www.thoughtworks.com/) for sponsoring our event and supporting our mission to foster a tight-knit community of software design practitioners. **Code of Conduct** We adhere to the [Berlin Code of Conduct](https://berlincodeofconduct.org/) to ensure a welcoming and respectful environment for all participants. **Spread the Word** We believe the more, the merrier!

Together with betahaus, we’re bringing the [12min.me](http://12min.me/) spirit into the morning. ​[12min.me](http://12min.me/) STARTUP is a three-part breakfast series, embedded in the well-known betabreakfast format. Instead of three speakers in one evening, we do things differently. ​One morning. One speaker. One focused impulse. ​12 minutes. One voice. Zero fluff. ​Join us for the first edition of [12min.me](http://12min.me/) STARTUP, a compact morning session for founders, operators, creatives and everyone building things that matter. ​**✔️ What to expect** * ​One inspiring startup-related talk * ​12 minutes of sharp insight * ​Curated exchange over breakfast * ​The familiar [12min.me](http://12min.me/) energy, just earlier in the day# ​ **The formula stays the same** * ​12 minutes talk * ​12 minutes of Q&A * ​12 minutes of networking ​The familiar [12min.me](http://12min.me/) energy, just earlier in the day ​** Our speakers** **Speaker 1 @March 5** **[Jonathan Hegel](https://www.linkedin.com/in/jonathan-beisiegel) from [FW Systems](https://www.linkedin.com/company/frachtwerk/)** Jonathan is the CEO of FW Systems, a specialized system house for open source solutions and IT services with a fixed-price model. After years in traditional IT, where he regularly had to work night shifts due to emergencies, he decided to do things better—for customers and for IT professionals. Today, he help SMEs transform their IT from a constant work in progress to a reliable infrastructure they can depend on. **Jonathan\`s talk: "How we are completely rethinking system administration as a service for your company"** Companies cannot possibly do everything themselves. So things like accounting, logistics, and IT are outsourced to external service providers. In the IT sector, system houses have been doing very well for themselves in recent decades! Every little thing is charged for, and if there are any errors, the customer is expected to open a ticket. We are rethinking this! We are applying the “as-a-service” concept from Airbnb, Uber, and Everstox to system administration and taking responsibility. Jonathan will show how this works in his talk. ​ **Speaker 2 @March 12** **[Anne Biedermann](https://www.linkedin.com/in/anne-biedermann/), independent wealth partner for women** Anne has extensive experience across venture capital, single-family-office & HNWI investing, and early-stage operations. She works with investors who are building, inheriting, or stewarding wealth on how to allocate capital with clarity — particularly where venture capital intersects with long-term wealth strategy. Anne also invests personally, giving her a practitioner’s perspective on capital allocation decisions. **Anna\`s talk: "Not All Capital Is the Same: Decoding Investor Behavior"** Founders often assume all investors evaluate risk, timelines, and returns the same way and that assumption is costly. This session breaks down how funds, family offices, and individual investors actually make decisions, where founder–investor misalignment typically begins, and how founders can better position themselves for the right kind of capital, not just any capital. **Speaker 3 @March 19** **[Immo Ait Stapelfeld](https://www.linkedin.com/in/immoaitstapelfeld/), Co-Founder & CEO at [913.ai](https://913.ai)** **"From Legal Complexity to Practical AI. How We Help Regulated Industries Use AI Without Losing Control"** This presentation tells the story of Immo’s transition from a trained lawyer working in mass proceedings to an entrepreneur building AI products for regulated industries. His legal background, combined with hands-on experience as a founder, shaped a pragmatic view on AI. not as a disruptive replacement, but as a controlled and compliant tool. At[ ](http://913.ai)[913.ai](https://913.ai), this perspective enables conservative organizations such as insurers to enter the AI era in a way that respects regulation, responsibility, and existing teams while still unlocking real efficiency gains. ​ **The series at a glance** [12min.me](http://12min.me/) STARTUP consists of three independent sessions.

Join this **Interview Simulation** session — to sharpen the skills for both interviews **and** architectural pitches. 💡 How it works The event is split into three parts: 1. **Answers for common behavioral questions** \- at the beginning\, I will read some common interview questions\, explain what they mean\, and give the correct answers\. 2. **Interview Simulation (10 minute rounds)** – One participant acts as the interviewee and answers a round of behavioral and design-focused questions. Each other participant gets to ask him one interview question. 3. **Feedback Round** – The group provides feedback on communication, structure, and clarity. Constructive criticism is encouraged. 💡You will be asked: * **Behavioral questions** (“Tell me about yourself”, “Describe a challenge you faced...”) * **Technical questions** (based on your tech stack) * **Light design problems** (high-level reasoning, not code) No need to prepare anything in advance — just bring curiosity and an open mind. Feel free to bring your CV if you’d like feedback from others, or share a few words if you’re currently job hunting. If so, we will also brainstorm answers to more common questions that you were asked. Whether you’re preparing for an interview or simply want to grow as a software designer or architect, this session is for you.

**PLEASE NOTE THE ADDRESS CHANGE! We're now at [w3hub.berlin](https://w3hub.berlin)** *[Qase](https://qase.io) is presenting the **eleventh** Meetup on Quality Engineering in Berlin.* *This time, we’re bringing you three deep-dive talks — all designed to challenge the way you think about quality, testing, and collaboration.* *As always, expect great conversations, snacks, and drinks. See you there!* **AGENDA** **1\. Mitesh Patel\, Technical Consultant \- Scientific Instruments @ Altum Solutions: *Food QA: Testing Tasting*** On this fine evening, we shall enjoy some food … and also learn why we enjoy it. Because tasting is really a form of testing for our brains — wetware QA in essence. But how do we reformulate this wetware testing into those familiar realms of software and hardware testing? It is not as simple as exchanging taste buds for test suites and bites for bytes. Just ask Big Food which spends billions on this same question: How can computers do taste tests like humans? Guided by the example of an ML/AI-powered scientific instrument for chemical analyses, namely, a spectrometer, this session addresses this question and explores the broader topic of QA in the food industry. Discover how food companies scale testing across scientific software, device hardware, and food/human wetware. So grab a spoon for this insider scoop on QA for food. **2\. Vitaly Sharovatov\, developer advocate @ Qase: *QA Myths Busting: A Practical Guide to Higher Quality*** Have you ever felt the urge to increase the amount of testing or hire more testers, thinking it would improve product quality? As a tester, have you ever been held “accountable” for quality or pressed for time, leaving you feeling helpless? Or perhaps you’ve been asked to justify quality assurance initiatives with numbers? Our industry is filled with myths: from “quality can be measured” to “more testing means higher quality” and from “QA slows down work” to “testers are responsible for quality”. In this talk, I will present the myths I once believed, explain the dangers they pose to both teams and products, and demonstrate how they should be debunked and overcome. **3\. Asya Isakova\, Co\-Founder @ TECH_Connect: 𝘌𝘢𝘳𝘯 𝘛𝘳𝘶𝘴𝘵\, 𝘒𝘦𝘦𝘱 𝘠𝘰𝘶𝘳 𝘑𝘰𝘣** The job market is wild: it’s hard to get hired, and sometimes even harder to stay hired. In a new role (or a new team), one of the fastest ways to reduce uncertainty and accelerate collaboration is to build trust quickly. But how do colleagues and managers decide you’re trustworthy? It’s rarely just about closing Jira tickets or moving cards on a Kanban board. People assess trust through patterns of behavior: what you do, how consistently you do it, and how do you act towards others. In this talk, you’ll learn an evidence-based approach to building trust at work using three practical components: integrity, reliability, and benevolence. We’ll unpack what shapes people’s trust judgments (including context, risk, and prior experiences) and translate research into concrete behaviors you can apply immediately: especially in multicultural and cross-functional teams.

Join our new group’s third meeting. Meet fellow tech enthusiasts west of the beltway. ​Because our group is new, we have a poll for the direction we want to take this new group. ​[https://submatrix.net/article/Meetups/e9ym4fr8Ca](https://submatrix.net/article/Meetups/e9ym4fr8Ca) ​For this event, we will be running a working meetup. ​Our meetings are a great place to work on and show off what you do. We are always welcoming. ​Our format is great for people who have started on but not finished one or several side projects. ​We will start off with basic introductions and what we are working on and what our goals are. We’ll break the rest of the meeting into two working sessions. In between, we’ll do a quick check-in to see how folks are going.

# ✨ Real Founder Lessons for Builders & Career Pivoters (Ashburn) **Saturday, March 14 • 2–4 PM • Ashburn, VA** What if growing your work didn’t have to come with constant exhaustion? This entrepreneur-focused session is a behind-the-scenes conversation about how to build, pivot, and scale **without burning yourself out** — and without chasing work that drains your energy. Whether you’re launching something new, navigating a career pivot, or rebuilding after a layoff, the principles are the same: 👉 protect your energy 👉 make smarter pivots 👉 build momentum that lasts 👉 apply AI practically to support smarter decisions and workflows Over 12 years, I’ve launched **7 startups and side hustles** — alongside **21 years in corporate tech leadership**. The biggest lesson wasn’t scaling tactics… It was learning when to pivot, how to sustain momentum, and how to align what energizes you with what serves your customers — an approach that generated **revenue** in my first full-time year without burnout. A key part of that evolution has been learning how to integrate AI in grounded, practical ways — helping accelerate testing, decision-making, and workflow clarity without adding complexity. During this session, I’ll share real founder insights — including a live screen walkthrough — showing how smart pivots happen and what separates intentional growth from reactive hustle. *** ## What We’ll Explore 1. **How to recognize when to pivot — and when to stay the course** 2. **Building energy-first systems instead of burnout cycles** 3. **Founder decision-making under pressure** 4. **Designing work that supports long-term momentum** 5. **Why sustainable growth outperforms hustle culture** 6. **Using AI strategically to support pivots, experimentation, and smarter workflows** This is not a lecture or pitch — it’s a grounded founder conversation for people who want to grow smarter and build work that lasts. Expect practical thinking, humor, and takeaways you can use immediately. *** ## Event Details 💵 $20 RSVP — includes coffee + snacks 📍 Ashburn, VA (exact address shared after RSVP) 🕑 2:00 PM – 4:00 PM 👥 Max 15 attendees — intentionally small for meaningful conversation Most attendees are professionals, founders, and growth-minded builders navigating reinvention, pivots, or startup ideas. *** ## About the Space — Startup Garage Style Hosted in my early-founder style startup garage — a **bright, spacious, comfortable Ashburn living room** designed for focused conversation and practical learning. These sessions are intentionally intimate — closer to a founder roundtable than a seminar. *** ## Background — Corporate to Founder Journey After **21 years in corporate tech leadership**, including senior director role, I transitioned into full-time entrepreneurship, building on years of startup and side-hustle experience. If you’re exploring a career pivot or next chapter, you’ll find this conversation highly practical. *** ## 🔗 Builder Ecosystem & Resources 🌐 Website: [https://midlifereinvention.co](https://midlifereinvention.co) ▶ YouTube (300K+ views): [https://www.youtube.com/@midlife_mindfulness](https://www.youtube.com/@midlife_mindfulness) 💼 LinkedIn (4K+ followers): [https://www.linkedin.com/in/anju-debnath-0061524/](https://www.linkedin.com/in/anju-debnath-0061524/) 🤝 Meetup Community: [https://www.meetup.com/ashburn-transition-meetup-group/](https://www.meetup.com/ashburn-transition-meetup-group/) 📚 Amazon Author Page (2 Books published, more on the way): [https://www.amazon.com/stores/Anju-Debnath/author/B0FFNBVZLQ](https://www.amazon.com/stores/Anju-Debnath/author/B0FFNBVZLQ) Everything shared comes from lived founder experience — not theory. *** **Space is intentionally limited to ensure focused discussion, interactive learning, and practical takeaways you can use immediately.**

The foundation of the group is built around the belief that everyone in the room has the potential to change the world… however most of us never have the time, energy or financial situation to even dare to dream big enough. Most of us have passions that will never be followed, amazing businesses or ideas that will never be pursued… unless we can solve the Cash-Flow Freedom Equation, which ultimately leads to Time-Freedom. Once that happens it is usually much easier for us to think bigger, dream bigger, be bigger. · Learn more about the Cash-Flow Breakfast Club [HERE](https://cashflowbreakfastclub.com/) · Get in the VIP List to be notified about the next event in your area [HERE](https://the.cashflowbreakfastclub.com/VIP) · Learn more about Launching your own Cash-Flow Breakfast Club Location [HERE](https://cashflowbreakfastclub.com/launch-your-own-club/) · Learn more about becoming an Affiliate-Sponsor at one of our club locations [HERE](https://cashflowbreakfastclub.com/affiliate-sponsors/) · View photos and videos of some of our recent events [HERE](https://cashflowbreakfastclub.com/about-the-cash-flow-breakfast-club/) · Looking to represent?

This training is designed for real estate agents who want to learn how to play the Agent Investor game. The goal of this training is to help you flip your income into ownership. ━━━━━━━━━━━━━━━━━ **Traditional buyers transact once every 7–10 years. Investors transact 3–10 times a year.** If you want predictable income, consistent deal flow, and a long-term wealth ecosystem, you don’t need more leads—you need a better list: a database of committed investors who buy repeatedly. The Investor Goldmine teaches you how to build, grow, and activate an investor database that becomes your most valuable asset in real estate. Instead of competing for one-time transactions, you position yourself as the Agent Investor—someone who understands strategy, leverage, and wealth building. In this session, you’ll learn the proven systems to build your investor list from scratch, including: * Where to network to meet real investors already buying * A simple “one lunch a week” strategy to build relationships fast * How to use giving and social currency to become the trusted connector * How absentee owners and business owners can become your best investor pipeline * Why community accelerates database growth—even if you don’t run one You’ll also get a clear activation plan to start growing and converting your investor database immediately. Because the model is simple: Build the list. Call the list. Market to the list. And your income becomes repeatable. ━━━━━━━━━━━━━━━━━ **Did you miss it?** [Watch all GRID Reston event playback on YouTube](https://www.youtube.com/playlist?list=PLOTh5kxLLJI1G3VH6Pqhlhu0uTA8yrdpi) ━━━━━━━━━━━━━━━━━ **Join the GRID Facebook Community** [Join the online GRID community here](https://www.facebook.com/groups/gridinvestor) to post deals, ask questions, and connect with other investors across the globe.
