Women Techmakers Berlin and SPICED Academy are joining forces to host an evening focused on both building *efficient AI systems* and navigating the real challenges of building a *career in tech*—beyond just learning technical skills. ## Talks Talk 1: Confidence Beyond Skills - What Really Holds Women Back in Tech Careers - by Marina Matveevskaia Many women in tech keep investing in new courses, skills, and certifications, yet still feel stuck or “not ready enough” to take the next career step. In this talk, we will look beyond technical competence and explore the less visible factors that often shape career growth much more strongly — such as self-trust, fear of visibility, internalized expectations, and the emotional impact of burnout or layoffs. I will share common patterns I see in highly capable women and why “just improving skills” is often not the real barrier. Participants will leave with new perspectives and simple reflection tools to better understand what is holding them back and how to move forward in a more sustainable and aligned way. Talk 2: Efficient Agentic Systems - by Jane Waithira Let Classical ML Do the Heavy Lifting, Let Agents Do the Thinking There’s a temptation to throw an LLM at every problem—but the most effective systems take a different approach. This talk explores how to combine deterministic, classical machine learning for predictable tasks with LLM-powered agents for reasoning and decision-making—so you can build systems that are fast, cost-effective, and reliable. ## Speakers **Jane Waithira:** Jane Waithira is an innovative, solution-oriented developer working in AI/ML, currently at SAP in Germany, where she integrates applied AI and GenAI for SAP's own cloud infrastructure. With over five years of experience building production AI systems, Jane has established her skillset in practical applications of ML and GenAI. Her talk will provide attendees with a practical framework for building efficient agentic systems that combine deterministic classical ML with the flexibility of LLM-powered agents.

The next **Berlin C++ Meetup** hosted by think-cell takes place on **Tuesday, May 26**. Join us for an evening with the Berlin C++ community! This meetup is a chance to step away from your day to day work, meet other developers, exchange ideas, and have real conversations about modern C++ in a relaxed setting. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- ## **Talk** ### **Contract assertions on virtual functions** *Timur Doumler – Citadel Securities* Contracts assertions were introduced in C++26, but they cannot be applied to virtual functions. To close this gap, we first need to answer the question: how should contracts assertions behave in the presence of inheritance and runtime polymorphism? In this talk, Timur explores why this problem is harder than it looks. He reviews existing approaches from other languages, such as Eiffel, D, and Ada, highlights why they don’t fully translate to C++, and outlines the key design challenges involved. He then presents a concrete proposal for how contract assertions on virtual functions could work in C++, balancing correctness, safety, and usability. Along the way, the talk touches on good API design, the true meaning of the Liskov substitution principle, and how to reason about program correctness. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- 📅 **Date & Time:** Tuesday, May 26, 2026 – 18:30–21:30 📍 **Location:** Le Wagon Coding Bootcamp, Rudi-Dutschke-Straße 26, 10969 Berlin 🕒 **Agenda** 18:30 – Doors open 19:00 – Talk + Q&A 20:40 – Pizza, Drinks and Networking \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **RSVP now to save your seat!**

Create the candle of your dreams in this premium scented candle workshop in Berlin, where creativity, sustainability, and craftsmanship come together. Hosted inside the Galleria Lucia Atelier, this immersive experience takes place in a historic artist building - a former factory now home to painters, designers, and makers. It's not a showroom or an office, but a real working candle atelier where so many candles come to life. During the workshop, you'll design a fully customized scented candle from start to finish. Choose your candle jar color, painted with sustainable, dishwasher-safe paints and designed to last up to 500 washes. Once your candle is finished, the glass can be reused as a drinking glass - making it both beautiful and responsible. Select from a curated range of premium fragrance oils, choose wax colors, finishes, and add natural crystals for a truly personal touch. You'll also create your own custom label, making each candle a one-of-a-kind piece. While you create, enjoy complimentary refreshments and learn expert tips on how to choose sustainable candles in the future and care for your candles so they burn cleaner and last longer. Surrounded by hundreds of candles and the authentic atmosphere of a Berlin candle atelier, this workshop offers a rare behind-the-scenes look into small-scale candle making - creative, intimate, and unforgettable. **Les Amis** is a women-only community of friendly souls.

Liebe Meetup-Community, schön, dass du hier bist. Suchst du gerade nach einem neuen Funken für dein Leben? Pass auf: Diese Veranstaltung wird dich vielleicht nicht nur unterhalten und inspirieren – sie könnte deine Sicht auf die Dinge (und damit dein Leben) grundlegend verändern. Wenn du bereit bist, lies weiter. **Findest du dich in einer der folgenden Situationen wieder?** * **Frust trotz Erfolg:** Du (und vielleicht dein Partner) hast eigentlich alles „richtig“ gemacht – Studium, Karriere, gutes Gehalt. Aber durch die Inflation und steigende Kosten fühlt es sich nicht mehr selbstverständlich an, eine hohe Lebensqualität zu führen (beim Einkaufen, beim Urlaub buchen oder beim Eigenheimkauf). Hinzu kommen Bedenken über die Altersvorsorge aufgrund des aktuellen Rentensystems. * **Was nun nach den ersten Schritten?** Du hast dich schon an Aktien, ETFs, Krypto, Immobilien usw. herangetraut, aber der Weg zu deinem Traumleben sieht noch unendlich weit oder ungreifbar aus. * **„Selbst“ und „ständig“:** Du hast den Schritt in die Selbstständigkeit gewagt, fühlst dich aber gestresst – sei es wegen der Finanzen, dem Zeitmangel für dich und deine Familie oder beidem. **Stell dir vor, du gehst nach diesem Abend so nach Hause:** * **Antrieb:** Du erkennst, dass dein eigentlicher Traum, den du vor Jahren in die Ecke geschoben hast, doch möglich ist. * **Klarheit:** Du weißt jetzt, was dein nächster Schritt ist – und du hast richtig Lust, ihn zu gehen! * **Freude:** Du stehst am nächsten Tag nicht mehr aus Pflichtgefühl auf, sondern aus echter Freude. **Was wir machen:** Wir treffen uns in lockerer Runde und spielen das **[Cashflow-Spiel von Robert Kiyosaki](https://en.wikipedia.org/wiki/Cashflow_101)**. Keine Theorie, sondern Spiel bzw. Simulation pur. Wir probieren auf dem Brett Sachen aus, die man im echten Leben vielleicht gar nicht sieht oder sich nicht traut – und lernen dabei extrem viel über unser eigenes Geldverhalten. Wir lachen viel, tauschen uns ehrlich aus und kommen als Gruppe weiter. **Der Plan:** * **18:30 Uhr:** Ankommen, Drink schnappen, kurz quatschen. * **19:00 Uhr:** Spielstart (ca. 90 Min.). * **Danach:** Offene Runde. Wir reden Tacheles – über Aktien, Krypto, Immobilien und deine persönlichen Erfahrungen. Steig ein – spielerisch, ehrlich und vielleicht ist das hier der Startschuss für dein neues Leben. Beste Grüße und bis dann, Shuying ========================================== **Wer wir sind:** Wir sind eine vielfältige Gruppe von Menschen, die entdeckt haben, dass strategisches Aktienhandeln für jeden zugänglich ist. Unser Ziel ist es, unsere gemeinsame Erfahrung zu teilen und Anfänger im Aktienhandel zu inspirieren, sich sinnvoll und emotionsfrei zu investieren. Wir glauben fest an das Konzept des gegenseitigen Lernens – indem wir dir helfen, lernen auch wir von dir, und schaffen so eine Win-Win-Situation für alle. **Was wir glauben:** * Erfolgreiches Aktienhandeln ist keine exklusive Domäne für Finanzexperten. * Das Verstehen von Aktien und das Treffen informierter Anlageentscheidungen ist für jeden erreichbar. * Du benötigst keinen Abschluss in Betriebswirtschaft, um die Prinzipien der Wertanlage zu verstehen. * Technische Aktienanalyse ist nicht nur für Finanzprofis gedacht; es ist eine Fähigkeit, die du erlernen kannst. **Über die Gründerin dieser Meetup Gruppe:** Shuying hat Mitte 2023 selbst ihren Weg zur Anlegerin gefunden – von der Frustration und Überforderung zur begeisterten Aktieninvestorin, nachdem sie die Grundlagen der Chartanalyse gelernt hatte. Inspiriert durch diese Erfahrung gründete sie diese Meetup-Gruppe, um andere auf ihrem Weg zu mehr Selbstvertrauen, Klarheit und finanzieller Freiheit zu unterstützen.

In the previous meetup, we discussed a difficult question: **Will AI replace Scrum Masters and Agile Coaches?** This session builds on that conversation. Instead of focusing on what might disappear, we’ll focus on: **What will become more valuable.** 🧠 **What you’ll learn** We’ll explore the shift from: * Why facilitation and process knowledge are no longer enough * The shift from team-level focus to system-level thinking * How organizational design becomes a key capability * What skills will make you stand out in the coming years Grounded in Org Topologies™, we’ll look at: * Why many roles operate in **output-driven, incomplete setups** * The shift toward **outcome-oriented, complete mandates** * Why organizational design becomes a **core capability** * How AI amplifies this shift rather than causing it 🔑 **Core idea** The future is not about becoming a better Scrum Master. It’s about becoming someone who can: * see the organization as a system * identify structural constraints * redesign how work, learning, and decision-making happen 🎤 **Format** * \~30 min talk * \~30 min Q&A and discussion * \~30+ min Networking 👥 **Who this is for** * Scrum Masters & Agile Coaches seeking their next evolution * People struggling to create impact in their current setup * Leaders interested in system-level change * Anyone thinking about their next career step 💡 **Why join** Many people feel that “something is changing.” This session helps you **name the shift** — and position yourself within it. Btw: This meetup prepares the ground for a special session with the author of *10xOrg* in June.

This talk walks through a production Text2SQL system built on four pillars: semantic models built on customer data, RAG-based semantic search, an agentic verification and correction loop for building the SQL, and an evaluation framework for the entire process. Raw schema information is not enough for text2sql to work. Rather, thorough documentation including business metrics, synonyms, and qualified example queries, are required. We'll cover how to automate this documentation pipeline by mining query logs, generating descriptions with LLMs, and organizing everything into a knowledge graph and vector search index. From there, we'll dive into the agentic flow that takes a user question and iteratively generates, validates, and fixes SQL against a live database. The agentic framework analyses syntax errors and execution results to help it fix the SQL. Participants will leave with practical takeaways on RAG architecture for structured data, agentic retry patterns, and how to think about evaluation for Text2SQL systems in production. **Speaker**: Oren Matar **Bio**: Oren Matar is a principal data scientist and algorithms developer, with a background in social sciences and Bayesian methods. He specializes in NLP and time series forecasting, as well as agentic methods for data retrieval and processing. **Talk 2: Interpreting and Communicating Statistical Models** **Abstract**: Extracting actionable insights from complex statistical models remains a challenge, as raw coefficients are often uninterpretable due to nonlinearity, interactions, or hierarchical structures. This talk introduces a unified framework for model interpretation based on the principles of the Marginal Effects project ([https://marginaleffects.com/](https://marginaleffects.com/)). We move away from internal model parameters toward quantities of interest, such as marginal effects and adjusted predictions that translate statistical output into the "natural language" of the data. We will demonstrate these concepts in Python using the Bambi interpret module, showcasing a seamless workflow for interpreting Bayesian models built on PyMC. The audience will learn how to use the four primary interpretative pillars: Predictions, Comparisons, Slopes, and Marginal Means to compute average marginal effects and visualize conditional relationships. By the end of this session, you will be equipped to turn sophisticated GLMs and multi-level models into clear, rigorous narratives that are easily communicated to stakeholders. **Speaker**: Juan Orduz **Bio**: Juan is a Mathematician (Ph.D. Humboldt Universität zu Berlin) and Principal Data Scientist at PyMC Labs. He is interested in interdisciplinary applications of mathematical methods. In particular, time series analysis, Bayesian methods, and causal inference. **Lightning talks** There will be slots for 2-3 Lightning Talks (3-5 Minutes for each) between the two main talks. Kindly let us know if you would like to present something :) \*\*\* NumFOCUS **Code of Conduct** THE SHORT VERSION Be kind to others. Do not insult or put down others. Behave professionally.
