Join us for a fascinating evening exploring how astrology can reveal repeating themes, emotional cycles, and inherited patterns within families. From shared Moon placements to recurring planetary aspects across generations, family charts often tell stories that echo through time. Together, we’ll look at how astrology may reflect: • Repeating emotional dynamics • Generational strengths and challenges • Parent-child similarities and contrasts • Family karmic themes and inherited lessons • Patterns in relationships, communication, and life paths This meetup is a space for curiosity, reflection, and meaningful conversation — whether you’re deeply into astrology or just beginning to explore it. Bring your birth chart and, if possible, charts from family members to discover the connections written in the stars. 🌙✨ **Guidelines**: – Start: 18:30 sharp (arrive earlier if you like) – Please stay on the topic of astrology – Respect, warmth, and honesty are essential – Kindly RSVP in advance, as we need to confirm with the venue Warm regards, Finja, Maca, Sara & Julian *We collect a 5€ cash contribution on site to support the platform costs.*

[Enpal Teams: Software Engineering](https://www.jobs.enpal.com/teams/software-engineering) **🕑 Event Schedule** 18:30 - Doors open - snacks, beer, socialization 19:00 - Intro and announcements **19:10 - From One App to Many: Scaling Frontend with Domain‑Driven Architecture - [Natalia Dmitrieva](https://www.linkedin.com/in/natalia-dmitrieva-652307124/)** **19.35 - The Fourth Platform: How Vega Got Us Surprisingly Close to "Write Once, Run Everywhere" - [Bogdan Plieshka](http://linkedin.com/in/gotbahn/?skipRedirect=true)** 20:00 - Break with drinks **20:15 -** **React Native in 2026: Not Your Daddy’s React Native - [Conor Lamb](https://www.linkedin.com/in/conorobrienlamb/)** **20:40 - Networking, Open Mic Lightning Talks** Mingle until 21:30pm 🗣️ **Talks** **➡️ From One App to Many: Scaling Frontend with Domain‑Driven Architecture - [Natalia Dmitrieva](https://www.linkedin.com/in/natalia-dmitrieva-652307124/)** *How we transformed a React monolith into multiple apps inside one codebase.* *You always start small: one product, one team, one stakeholder. But once you succeed and need to scale, your original frontend architecture might not be ready for what comes next. As our Sales Process Orchestration Platform expanded to support multiple products and sales channels, our original monolithic application became a bottleneck.* *In this talk, I'll share how we transitioned to a domain‑driven, multi‑app architecture while deliberately keeping a single React codebase. You'll see how we applied Domain‑Driven Design concepts on the frontend, structured clear boundaries between sales channels, and used Nx to orchestrate builds, enforce architecture rules, and keep teams moving independently without losing shared foundations.* **➡️ React Native in 2026: Not Your Daddy’s React Native - [Conor Lamb](https://www.linkedin.com/in/conorobrienlamb/)** *React Native has changed a bunch, and if you haven't looked at it lately you're in for some fun. We'll walk through building a real app with (my beloved 😍) Expo. Talk about project setup to app store submission with detours into AI-assisted development and ofc, talk about the casual masochism that is mobile dev.* **➡️ The Fourth Platform: How Vega Got Us Surprisingly Close to "Write Once, Run Everywhere" - [Bogdan Plieshka](http://linkedin.com/in/gotbahn/?skipRedirect=true)** *"Write once, run everywhere" is a promising goal in software development, but one that often breaks down under real-world problems. At Zattoo, building streaming applications across Android, Apple, and Web meant years of separate native stacks that were not aligned, and therefore did not scale. This talk explains how moving to a multiplatform architecture, enabled by Vega as a fourth (React Native first platform), brought us very close to achieving that goal.* — **👍 Code of Conduct** By registering for this event you agree to comply with our [CoC](https://portal.gitnation.org/coc) **📩 Contact** events@gitnation.org [https://twitter.com/ReactSummit](https://twitter.com/ReactSummit) [https://bsky.app/profile/reactsummit.gitnation.org](https://bsky.app/profile/reactsummit.gitnation.org) [http://youtube.com/ReactConferences](http://youtube.com/ReactConferences)

! All sessions in English except for 24.03, 21.04, 09.06, 28.07 & 01.09- these sessions will be in German ! Wanting to connect deeper with your partner? Looking for new ways to be intimate? Hoping to foster love, awareness, and communication in your relationship? Take some quality time away from the daily grid and explore Tantra together through embodied practice. The practice is designed to foster deeper intimacy, attunement and harmony between the two of you. Tantra invites you to allow your life force energy to flow without inhibition and to cultivate it for self-realization. Part of the practice is about inviting in more opening. Openness creates union, resistance creates separation. Deep connection, more pleasure and joy are a result of experiencing more openness. Tantra is for everyone! All couples are welcome regardless of sexual orientation and experience level. Not in a romantic relationship? Feel free to bring anyone you'd like to practice Tantra with. **What to expect:** * **Discourse, demo practice and Q&A**: learn about Tantra through discourse, ask your questions * **Tantra meditation practice**: presence, movement, sound and breath * **Sharing before and after practice**: share about your fears and desires & reflect on your experience * **Cozy studio setting**: enjoy a comfortable and intimate environment * **No partner-exchange:** practice only with your partner * **Fully clothed:** you may keep your clothes on during the entire practice **What to bring:** * Wear comfortable clothing * Water bottle to stay hydrated **Tickets:** 69€ per couple. Please purchase your ticket via [sophieheldens.com](https://www.sophieheldens.com/tickets?utm_source=meetup&utm_campaign=datenight) **Location:** Praxis Köpi Köpenicker Straße 175 10997 Berlin Kreuzberg Walk to the second courtyard and take the stairs to the front door on the left. **Please note:** Praxis Köpi is located on the 5th floor and there is no elevator available. Only book a ticket if you can walk the stairs. The benefit: a beautiful private studio with loads of natural light. **!! Please arrive 10 minutes early so we can start on time !!** Once we start the session, I can’t let you in anymore because it disturbs the class. Please do yourself and the group a favour by coming on time. Thank you! **Workshop facilitator** Hi! My name is Sophie. My passion for Tantra is rooted in a deep spiritual yearning and an inner knowing that Tantra is my path. My desire to teach Tantra has been sparked by having witnessed my own growth and healing as a result of these practices and it is inspired by a vision to create a more beautiful world. I create a space that is loving and nurturing, with a strong emphasis on ensuring that you feel save and supported. My workshops are gentle yet transformative, spiritual yet grounded and always heart-centered. I'm passionate about bridging the wisdom of ancient Tantra with modern-day practices.

Hallo, Willkommen zur Handarbeits- und Gesprächsgruppe! Wir treffen uns von 14 bis 16 Uhr in der Psychosozialen Initiative Moabit. Bei Kaffee/Tee und Kuchen sitzen wir in entspannter Runde zusammen und arbeiten an Strick-/Häkel- oder anderen Handarbeitsprojekten oder ähnlichem und kommen so auch gerne ins Gespräch. Alle sind herzlich willkommen (auch ohne Strickerfahrung!!). Wir haben vor Ort auch ein paar Stricksachen und Wolle, die alle mitbenutzen können :) Hello, Welcome to the crochet/knitting group at Psychosoziale Initiative Moabit! We meet up every Wednesday from 2 to 4pm and all work on our creative projects. Throughout the crafting you have the space to talk and expand your community in Berlin. Everyone is welcome (even if you've never done crocheting/knitting before!!). We also have some knitting needles and yarn for you to use :)

In May, [Bruno Caballero](https://github.com/bruno-ah-um) will show us how to target hardware accelerators from Java with MLIR based on [his fork of the OpenJDK Project Babylon](https://github.com/bruno-ah-um/openjdk-babylon-mlir-tosa). Bruno leads the Java Virtual Machines Engineering team at [MicroDoc](http://www.microdoc.com), which develops JVMs and maintains ports across various processors and operating systems. In this talk, we’ll explore a toy project that translates Java code into MLIR for the TOSA dialect, which is used for AI and accelerator workloads. We’ll briefly introduce current approaches (e.g., TornadoVM and Babylon/HAT), before looking at how this project reuses existing compiler infrastructure instead of building new backends. Finally, we’ll touch on whether DSLs should be embedded in general-purpose languages like Java or designed as standalone languages. Small snacks and drinks will be available. There is always space for outside topics and discussions. If you have specific questions, please bring them. Looking forward to meeting everyone again!

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.

Wie jedes Jahr versammelt sich die Bitcoin-Community in Berlin, um den legendären „Bitcoin Pizza Day“ zu feiern. Die Transaktion von Laszlo Hanyecz gilt als eine der ersten bekannten Zahlungen mit Bitcoin für reale Güter: 10.000 Bitcoin im Austausch gegen zwei große Pizzen. Zur Feier dieses historischen Moments treffen wir uns dieses Jahr im Restaurant Viale dei Tigli. Auch dort werden Bitcoin-Zahlungen akzeptiert und natürlich gibt es Pizza. **Bitte beachtet: Jede Person bezahlt ihr Essen und ihre Getränke selbst vor Ort.** Das Ganze ist als lockeres Get-together ohne feste Agenda gedacht – einfach zusammenkommen, austauschen und gemeinsam Pizza essen. Wir freuen uns über viele Teilnehmer. Da die Plätze begrenzt sind, bitten wir um möglichst verbindliche Zusagen. Vielen Dank.

**We’re back!** After a break, the Berlin Tech Leads meetup is officially revived **\- and this time IRL at Berlin Vinted office\.** **We’ve missed the deep dives, the architectural debates, and the networking. To kick things off, we’re tackling one of the fastest-moving landscapes in the industry right now: the intersection of Engineering and Customer Support.** **About the Event** Customer Support is often the first place where AI moves from "experimental" to "mission-critical." For Tech Leads, this shift isn't just about plugging in a basic chatbot; it’s about re-engineering the entire lifecycle of a ticket and how our systems actually interact with our users. In this meetup, we’re looking under the hood of the support stack. We’ll discuss how the landscape is being reshaped by LLMs, the shift toward autonomous agents, and the real technical hurdles of building multi-modal support systems. **Talks:** * [Pau Agustín](https://www.linkedin.com/in/pau-agust%C3%ADn-granell-6420a5139/) & Team Help Experience (vinted.com): "Scaling Support: How Vinted Manages Tens of Thousands of Tickets Every Day" * [Yam Marcovitz](https://www.linkedin.com/in/ACoAAAbVVAwBOgouy-uT1QB1ixhqrafAv1kNxQk) (parlant.io) "Building consistently aligned agents with Parlant" * [Richard Lohwasser](https://www.linkedin.com/in/ACoAABRCCmYBD9PS9O73AjQ244LC4Gc_NMUcnsY) (enneo.ai): "Applying AI across all channels in real-life customer service at scale: What works, what doesn't, and where we're heading to?" *Just a quick reminder: if you'd like to take the stage and speak at a future Berlin Tech Leads meetup, feel free to drop a message to one of the organisers.*

It’s time to take control of your mental health. How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind. Find out what the reactive mind is, and in the process find yourself. Have you ever suffered from a traumatic experience, a deep loss or been through a painful breakup? Has your ability to communicate suffered as a result? And after that, even though you "moved on" did you find that things were never quite the same? Have you ever looked at childhood photos, or reminisced your early life and wondered where that happiness and spark went? Are your emotions out of your own control? Have you ever felt, even if you aren’t aware of it, that possibly you are getting in your own way of your happiness and success? How does this affect your self-confidence? Find out what is at the root of all stress, anxiety, depression and self-doubt. Find out how and why you hold yourself back from achieving your goals and having the life you have dreamed of. As soon as you learn what is at the root of these unwanted conditions, you’ll see it is something you can DO something about. You will not be labeled or categorized at this MeetUp.

Bring your work or your hobby, hang out, and code with us. Follow @buckeyecocoa for more information.

Feeling down? Sometimes depressed? Can't focus? Negativity & stress? Recent losses? Creativity in career and personal life hindered by mental blocks? Sometimes we never fully recover from traumatic experiences. Whether it was yesterday, last week or a year ago, traumatic experiences - a loss of a loved one, losing a job, a breakup - can leave you scarred. You talk about it and feel a little better, but it never goes away. After you hang up the phone, it's still there; the sadness, the cloud, the over-thinking, the worry, the guilt. You try to focus, but you're blocked. You try to look forward into new experiences, new relationships but a cloud is hanging over you, casting a shadow on what you once considered a bright, cheerful future. What happened to your courage? Your strength of character? You're 'why not' attitude? Whoever said 'time heals' must have had a special time machine, because after weeks, months, years, you're wondering - when exactly does that kick in? Sometimes it seems like drinking or drugs are the way to go. But they wear off, and now the problem is still there with added side effects from the drugs. At this free local Meetup event we will talk about: * What causes grief, anxiety and depression to become chronic. * Is it possible to regain your joy and happiness even after traumatic experiences? * How to break away from negativity and focus on the future * What are the steps to take to get control of your mind and your emotions? Learn about a safe, gentle, do-it-yourself counseling that can be done in the comfort of your own home. Let's explore safe, effective solutions for healing from traumatic experiences. Be sure to click on the red "Attend" button below to come to the event. We look forward to seeing you there. This group is sponsored by the Dianetics & Scientology Life Improvement Center.
