Join us on February 26th in Berlin and bring all your questions! : ) **Pawel Wiszniewski: *"From Ingestion to Insight: Flink’s Data Platform Ecosystem"*** [Pawel Wiszniewski](https://www.linkedin.com/in/pawel-wiszniewski/) is a Senior Data Engineer at[ Flink](https://www.goflink.com/shop/de-DE/deals/?campaignid=23008119587&adgroupid=190905032608&creative=676430819949&utm_source=google&utm_medium=search&gad_source=1&gad_campaignid=23008119587&gbraid=0AAAAABiSYNQr0V_xYSzvjjStCH6G-hLqP&gclid=CjwKCAiAkbbMBhB2EiwANbxtbQ-a9DxijUVV0nw5nXTXr037lYGiy6MIv5YbFjeo1qsZJStEPdBNxxoCPFQQAvD_BwE) and a well-known face at our Data Engineering Meetups. We're super excited to see our guest now stepping into the presenter's role. About his keynote: "You have data, analysts, and business use cases. But you can't simply stitch them together with spreadsheets, SQL queries, and Python scripts and still expect business users to trust the dashboards. To ensure data quality, reliability, security and freshness, you need a well organised set of tools and processes: a Data Platform. In this presentation, I will explain how the Data Platform at Flink was built, outline its high-level architecture, and describe the key products, tools, and processes that enable us to operate over a thousand data models and maintain full visibility into the current state of the business." **Sneha Nafade: *"AI Agents & Agentic Deployment"*** [Sneha Nafade](https://www.linkedin.com/in/sneha-nafade/) is a Cloud Architect at [Diconium](https://diconium.com/en/?utm_term=&utm_campaign=2025+%7C+Remarketing+%7C+DE/EN+%7C+All+Visitors&utm_source=adwords&utm_medium=ppc&hsa_acc=9083156072&hsa_cam=23281606208&hsa_grp=&hsa_ad=&hsa_src=x&hsa_tgt=&hsa_kw=&hsa_mt=&hsa_net=adwords&hsa_ver=3&gad_source=1&gad_campaignid=23483494785&gbraid=0AAAAADQqBJ6jY8TgZt7Ocjy37F5Gup62I&gclid=CjwKCAiAkbbMBhB2EiwANbxtbfuZyXSVyFENwFuHv9tAcygFWNM24hiXlk3rvKVpwBFfM__jFEBHBRoCMpsQAvD_BwE) with a rich experience in Cloud & Cybersecurity Architecture & Engineering.

**Welcome to a new Mask-making Workshop!** As Carnival approaches, we are excited to invite you to a new, two-day hands-on mask-making workshop inspired by folk devils, spirits, and popular mythological figures from Latin America and Central America. This workshop combines cultural references, imagination, and craft, inviting participants to create their own expressive folk mask using recycled materials. No previous experience is required. In this context, devils are not symbols of evil. They represent creative **chaos, irony, protection, transformation, and vital force.** These figures often blur the line between human, animal, and spirit, appearing as guardians of the land, playful tricksters, or exaggerated reflections of social power and fear. **Day 1: Symbols, Archetypes & Design** We begin with a short cultural introduction about what the “devil” represents in Latin American folk traditions. We will explore visual examples from traditional masks and popular celebrations: folk spirits, tricksters, and hybrid animal–human figures. We will then choose a personal archetype to work with. Using a template as a base, and through quick sketches, we will design and define: •⁠ ⁠Expression: rage, irony, mystery, laughter. •⁠ ⁠Horns, nose, fangs, beard, beaks, ears, snouts •⁠ ⁠Human, animal, or hybrid forms By the end of Day 1, each participant will have a clear mask concept and begin **building the base structure with recycled cardboard and paper-maché**, which will be left to dry before the second session. **Day 2 — Painting & Finishing** We will bring the masks to life through finishing, colour, textures, and expressive accents. You will get insights on choosing your colour palette, mixing colours and painting with acrylic to get different finishing effects. The workshop closes with a collective sharing moment, where participants can present the character, spirit, or creature behind their mask. **Dates:** Friday 20 + 27.02.26 from 5 to 8PM. **Address:** In Friedrichshain. Exact address by e-mail. **Price:** 110€/ 90€ for regular students. Materials are included as well as drinks and snacks. **Materials:** All basic materials are included (Cardboard, paper, paste, papier-mâché, acrylic colours, fabric and thread, natural elements such as seeds, wood, fibres, or decorative details) We encourage you to bring your unique elements (your own special colours, personal materials or objects, small found items, fabrics, feathers, textures, or symbolic elements connected to your mask) **How to sign up?** Please send an email to **hola.berlinartclub@gmail.com,** and you will receive the registration form with all the details of payment and the exact address. Limited spots. About the teacher: **Rosi Diaz Roigt** is a graphic designer and illustrator with over 7 years of experience working with film production teams, bringing fictional characters to life through graphic design, prop creation, and movie posters. Passionate about art and sustainability, she specialises in exploring the creative possibilities of recycled materials. Her work draws inspiration from the beauty and power of nature, blending storytelling and eco-conscious design. **Find her work here:** [https://www.instagram.com/avant.rosi/](https://www.instagram.com/avant.rosi/) See you!!

Join our **CATAN** Meetup to play, socialize, and enjoy this classic board game. Everyone is welcome, whether you’re a beginner or an experienced player. Expect fun, friendly games, plenty of laughter, and the chance to make new friends. This is a relaxed, casual meetup: **no hardcore competition**, just friendly rivalry. 👉 **Please RSVP only if you plan to attend.** *** **How to Play (Quick Guide):** * **Setup:** Build the island with hex tiles, place number tokens, roads, settlements, and give each player starting resources. * **Turn order:** On your turn, roll two dice to produce resources, then trade and build. * **Resource production:** Players gain resources (wood, brick, sheep, wheat, ore) from tiles next to their settlements/cities when the tile’s number is rolled. * **Robber:** If a 7 is rolled, players with too many cards discard half; move the robber to block a tile and steal a card. *NOTE: Friendly robber rule: We play with the friendly robber rule, which means that the robber cannot be placed on a player with less than 3 points.* * **Trading:** Trade resources with other players or with the bank (usually 4:1, better with ports). * **Building:** Spend resources to build roads, settlements, cities, or buy development cards. * **Victory points:** Earn points from settlements, cities, development cards, Longest Road, and Largest Army. * **Winning:** The first player to reach 10 victory points on their turn wins. * 2-Hours-Max: If no one reaches 10 points by the end of the second hour, the player with the most points wins. This keeps our game capped at **two hours**. ⏰️ *** **Our Game Set-Up & Attendance Policy:** 1. We will have two CATAN sets available for up to six players each, assigned on a first-come, first-served basis. 2. Since each game takes a considerable amount of time, arriving after a game has already started may make it difficult to place you at a table. 3. In such cases, you may need to place your first two settlements on the remaining available parts of the map—if space allows. 4. Please make sure to update your RSVP in advance. Failure to do so may cause unnecessary delays for everyone at the start. 5. Not showing up without notice will result in being blacklisted for at least one future meetup. ***

Classes every Monday, Wednesday and Friday from 19:00 to 21:00. **!!SIGN UP HERE**: [Katori Shinto-ryū Berlin Sign-up (google.com)](https://docs.google.com/forms/d/e/1FAIpQLSeBt4A13VgnEcgQQ2PDaruthmYMRWineG4KtUCKsuC9KBsCUQ/viewform) Registration is required before your participation so that we can prepare enough training equipment. **Address**: Belziger Str. 25, 10823 Berlin. **No previous experience required!** The classes are in English and German. **Our website**: [Kenjutsu Berlin - Official school of Katori Shinto-ryu in Berlin (katoriberlin.org)](https://katoriberlin.org/) **Katori Shintō-ryū** is one of the oldest Japanese sword fighting traditions (koryū) still practised today and is recognized by the Japanese government as a cultural intangeable asset. The school was founded in the middle of the 15th century by Iizasa Chōisai Ienao at the Katori Shrine (Katori jingū) and has become the origin of numerous other martial arts schools over the course of its almost 600-year history. The training consists of the continuous repetition of fixed sequences of movements (kata) and includes the use of classic Japanese weapons such as the sword (iai-jutsu, battō-jutsu, ken-jutsu, ryōtō-jutsu, kodachi-jutsu), the long staff (bō-jutsu), the lance (naginata-jutsu) and the spear (sō-jutsu), as well as unarmed disciplines, tactics and spiritual aspects. **The Katori Berlin dojo** is the only official shibu of Otake Nobutoshi-shihan’s dojo Shinbukan in Germany and fully dedicated to the transmission and study of one martial tradition: Tenshinshō-den Katori Shintō-ryū. Through these efforts we aim to contribute to the cultural preservation of this martial tradition. The dojo has one officially appointed shidosha. **Our sensei**: Sebastian Graetz has been active in martial arts since 1997. After almost 15 years of taekwondo in Berlin, he started with Katori Shintō-ryū in Asia in 2014. Since then, he has studied in Japan with Ōtake Risuke-shihan and Ōtake Nobutoshi-shihan, and in Vietnam with Malte Stokhof-shihandai. In 2023, he received his Menkyo license and permission to set up a training group in Berlin the following year.
