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.

This event is designed for hands-on product managers and product builders who want to improve their workflows and rethink how products are built within their organizations. **Agenda** 18:15 – Doors open for snacks, drinks, and networking 19:00 – Welcome from ProductTank Berlin 19:10 – Demystifying AI: A Productivity Playbook for Product Managers, Daniel Zherenkov 19:40 – Building with AI: How Smart Prototypes Become Real Products, Ruslan Vorobev 20:10 – Networking 21:30 – Event ends **Please note:** * **Please bring your IDs as you’ll need it when entering the venue.** * The event is RSVP only: to enter, you must RSVP here on Meetup. * We'd like to capture the event with photographs for promotional purposes, such as sharing on LinkedIn after the event. If you have any concerns or preferences regarding this, please feel free to let us know beforehand. **Demystifying AI: A Productivity Playbook for Product Managers, Daniel Zherenkov** To harness the power of AI, you first need to understand it. Join this session to strip away the FONO tropes from LinkedIn and understand the reality of today's AI capabilities. We will explore practical frameworks for integrating AI into the product management daily life, empowering you to make better decisions, streamline workflows, and build superior products. About the speaker: Daniel, ML/AI Product Manager at Delivery Hero with 8+ years of experience in creating ML and AI products, will explain what AI actually is and how to squeeze the maximum efficiency from it based on the real examples that could be reproduced by anyone. **Building with AI: How Smart Prototypes Become Real Products, Ruslan Vorobev** The talk looks at how AI can turn quick prototypes into real, valuable products. Ruslan shares practical lessons from using tools like Lovable, GPT, and internal automations to move from idea validation to production-ready solutions. The focus is on finding where AI truly adds value, whether through lightweight assistants or deeper integrations, and where it’s better left out. About the speaker: Ruslan Vorobev is Head of Product with a strong focus on innovation and AI-driven solutions. He has overseen product and business development across sustainability, circular economy, and manufacturing domains, helping scale digital products from early prototypes to market-ready solutions. His work combines hands-on experimentation with practical automation to turn ideas into tangible impact.

Hello everyone, After a great restart last month, we’re happy to invite you to the next Rust Berlin meetup at the JetBrains office. We’ll stick to the classic format: an evening with two main talks, followed by time to connect, discuss, and catch up with the community. Finger food and drinks will be available throughout the evening. **Agenda** * Doors open: 18:30 * Start: 19:00 * Short welcome and updates from JetBrains * 2 talks (20–30 minutes each) * Open mic / lightning talks (optional, a few minutes each) * Networking **Speakers** Egor Lebedev - Welcome and a short note from the RustRover team Till Adam - Slint-MCP In this talk, Till will walk you through the implementation of the MCP server for the Slint GUI framework - and how it's implemented in Rust. He will walk you through the implementation from design to implementation. Gaurav Gahlot - Rust meets Kubernetes This talk is a hands-on walkthrough using kube-rs. We'll connect to a cluster, query pods, watch real-time events via async streams, and build a minimal controller - all in Rust, all running live. **Speaker Bios** Till Adam is the CCO at KDAB and has been working on open-source since the 90s. Originally a C++ company, KDAB has been working with Rust for the last 8 years. One of their biggest projects is CXX-Qt. Their specialization on the Rust side is use in hybrid, high-performance, high-correctness codebases. Gaurav Gahlot is a Software Engineer with experience building scalable platforms with Go, Rust, and Kubernetes. He maintains the CNCF Akri project and actively contributes to open source. **Open mic & future talks** We’ll reserve a few short slots for anyone who wants to share something with the group. This can be a quick idea, a project, or an experience. Slides are optional. If you’re interested in giving a longer talk at a future meetup, this is also a good opportunity to connect with the organizers. **Venue & access** Please arrive on time. We will have someone at the entrance to let people in between 18:30 and 19:15. After that, access becomes more difficult as the doors are locked and require manual opening. **Registration** The venue has limited capacity and events typically fill up with a waiting list. If you register and can no longer attend, even at short notice, please un-RSVP so someone else can take your spot. Looking forward to seeing you all!

**PyBerlin:** April event **Sponsor**: Deepset **Location:** Deepset, Zinowitzer strasse 1, 10115 Berlin, 3rd floor **Agenda:** **6:30 pm – Doors open: snacks, drinks, networking** **6:55 pm - Welcome from PyBerlin** **7:00 pm - Welcome from the sponsor - Deepset** **7:10 pm – How to stay visible, relevant, and grow in Tech’s biggest shift // Valentina Scipione** The AI shift is changing what companies build, how they hire, and what they expect from engineers. Underneath all the noise, the questions that come up most are still very human ones. What should I focus on next? How do I stay relevant? What actually makes a difference when everyone has access to the same tools? This talk cuts through four common myths about tech careers in the AI era, reframes the "AI race" narrative, and explores what genuinely sets people apart, whether they are early in their career, deep into a job search, or a senior engineer thinking about what comes next. Speaker's bio: Valentina Scipione is an Engineering Manager and ICF-certified Career & Leadership Coach with 12+ years of experience in tech and a background in Astrophysics. She has led full-stack teams, hired and developed engineers, and coached software and data professionals through growth and career transitions. She works at the intersection of technical leadership and human development, helping people navigate change, find clarity in uncertain environments, and grow in the age of AI. **7:40 pm - break** **8:00 pm – Scheduling a small conference with the z3 solver // Ben Clifford** Ben has helped organise an annual one day academic conference for the last 7 years. At some point, it got just slightly too annoying to schedule all the talks by hand, and Ben decided to overengineer a solution using the z3 SMT solver. It worked well enough that he did it again the next year. This talk will cover: what an SMT solver is (spoiler: you give it constraints and it find solutions to those constraints), how the conference schedule was modeled as constraints, how this is embedded in Python to give a more normal helper language, and finally how to look for better solutions rather than just any solution. Speaker's bio: Ben has wide interest in programming languages, and this talk brings together a couple of his big interests: Python as his main work language and z3 implementing a more formal logic language. When he's not at work, he likes bikes and LEDs. **8:30 pm – Haystack // David Batista** Haystack is an open-source framework for building production-ready AI pipelines. In this session, we'll show you what that looks like in practice. We'll take Vision-Language Models as our example: AI systems that reason over both images and text. You'll see how Haystack lets you turn that raw capability into a working agent, one that interprets visual and textual input, decides what to do next, calls tools, and maintains conversational state. We'll also show how to handle the decisions that shouldn't be fully automated, with human-in-the-loop escalation built in from the start. Speaker's bio: David Batista is an experienced Machine Learning Engineer and Software Developer with a background in Natural Language Processing. He holds a Ph.D. (2016) and is currently based in Berlin working as an NLP Engineer and Software Developer at deepset, contributing to Haystack, the open-source framework for building end-to-end production-ready LLM applications. **9:10 pm - closing** This event will be only in-person. Please check our Code of Conduct and official health regulation in Berlin before coming. If you feel some signs of sickness, please consider skipping this event and attending another time. We will have plenty of events in different formats in the future. Looking forward seeing you all!
