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.

Do you like to play football - but relaxed and not with competitive or aggressive players? Are you a bit lazy, a bit old, a bit unfit or not so talented? Are you tired of insecure bros who only want to show off their skills? **Then [Lousy & Lazy Football](https://www.instagram.com/landlsc/) is the right thing for you!** We are a group of friendly people who just want to have a relaxed kick. All genders, ages (+18) and nationalities welcome. **Feel free to join the waitlist even if it seems long - sometimes we make the event larger and play on two pitches (24 players, four teams) or even three pitches (36 players, six teams), depending on demand.** Note: **We do not allow high-studded football boots during our sessions.** To avoid injuries, we only play with "Multinocken" (multistuds) or shorter. Please have a look here: [link](https://www.11teamsports.com/de-de/fussballschuhe/multinocken/). Rules for lazy & lousy football 1. **Don’t be competitive** 2. **No hard tackling/sliding challenges** 3. **Support new players by giving them the time and space to play the ball** 4. **Don’t dribble past multiple players (trying to take on a player is fine but at no point should you be trying to dribble past multiple players).** 5. **Don’t close down the defenders too quickly. Give the team a chance to play the ball out.** 6. **Rotate the goalkeeper** 7. **Be a teamplayer** Waiting list: This meetup is for members of the Lousy & Lazy Sport Club. If you want to try out our lousy & lazy sport events, you can do a trial run (Probetraining).

Planning to go on parental leave while working in tech? You probably have a ton of questions, and we will do our best to get you answers. Whether you're expecting, currently on leave, planning ahead or wanting to support your teammates, navigating parental leave comes with a lot of new challenges. Technical careers require us to stay up to date and living in Germany adds another layer of bureaucratic hurdles to the mix. To help you feel more prepared, we have selected panelists who've been through it and will share their experiences openly: what worked, what surprised them, and what they wish they'd known. We'll cover the practical and bureaucratic side, the career side, and we'll reserve time for your questions. **🗓️ Agenda** 6:30 Arrival and networking 7:00 Welcome and Intro 7:10 Panel Discussion: Planning Parental Leave in Tech 9:00 Event ends **Panel: Planning Parental Leave in Tech** ● **Saranya Parvathi Ganesan**, Senior Software Engineer @Immoscout24 ● **Sinny Kumari**, Associate Engineering Manager @Red Hat ● **Vanessa Ating**, Senior Frontend Engineer ● Moderated by: **Vaishali Thakkar,** Confidential Computing Expert @SUSE **🍕 Food and Drinks** There will be vegetarian and vegan food and beverages sponsored by our host Bettermile. 🗣️ **About the Panelists** **Saranya** I’m a mother to a four-year-old daughter and currently work as a Senior Software Engineer at ImmoScout24.

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.

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.

**Berlin, let’s talk agents. 🚀** We’re bringing the local AI community together for another evening focused on the fast-evolving world of **generative AI and autonomous agents** — and how teams are turning them into practical, scalable solutions. The meetup will feature a short session on what it really takes to **operationalize AI agents**: from design and deployment to oversight, orchestration, and management in production environments. After that, the floor is yours — with plenty of time to meet other builders, exchange perspectives, and continue the conversation over food and drinks. **What to expect:** 🎤 A featured talk on building and managing AI agents in practice 👀 A closer look through live demos 🤝 Informal networking with AI practitioners, builders, and innovators 🍻 Discussions with the Berlin data & AI community over drinks and pizza Whether you’re already experimenting with multi-agent systems or just starting to explore the space, this meetup is a chance to hear how others are approaching the challenge, share ideas, and connect with peers in Berlin.
