Extreme Programming

What happens when PMs stop watching engineers code — and start shipping themselves? You’ve probably heard the stories. Maybe you’ve already tried it in your own company. AI is changing how product teams build, collaborate, and ship — fast. Join us for an evening with product leaders sharing real-world experience building and shipping customer-facing features with AI, not just internal demos and experiments. We’ll talk about PMs opening PRs, non-devs contributing directly to production, and what actually changes when the whole team gets closer to the codebase. This event is designed for Product Managers and Product Leaders who want to understand how product roles, collaboration, and development processes are evolving in the AI era. **Agenda** 18:15 – Doors open for snacks, drinks, and networking 19:00 – Welcome from ProductTank Berlin 19:10 – Opening the PR is just the beginning, Dmitry Gorshkov 19:40 – What happened when we let non-devs into the codebase, Elena Berendeeva 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. **Opening the PR is just the beginning** Dmitry will show how to go deep into the codebase as a PM and make it worth the effort. Crafting code is time consuming, so should PMs code instead of doing PM work? Absolutely. But you must come prepared. About the speaker [Dmitry Gorshkov](https://www.linkedin.com/in/dmitrygorshkov?utm_source=share_via&utm_content=profile&utm_medium=member_android) is a lead product manager at Finom, a Dutch fintech superapp for small businesses. Dmitry has shipped successful products at N26, Taxfix and Cut the Rope, among others - and has more than a decade of product management experience. **What happened when we let non-devs into the codebase** A year ago, we let PMs, designers, and QA contribute directly to our existing codebase using AI. What followed wasn’t just faster shipping – it was a quiet shift in how our team made decisions, handled ownership, and thought about their roles. This is that story. About the speaker [Elena Berendeeva](https://www.linkedin.com/in/berendeeva-elena?utm_source=share_via&utm_content=profile&utm_medium=member_android) is a PM at JetBrains who spent the last few years building 0-to-1 products – through pivots, sunsets, and a lot of uncertainty. Her most recent product is Matter, an AI prototyping tool that her team – designers, QA, and engineers – used to ship directly to production. She explores AI-native workflows and the evolving role of PMs in agentic product development.

Hello fellow Symfonians, we are thrilled to announce something we've never done before: a **Live Code Review** session! This time it's not about slides and talks – it's about your code. Submit a snippet beforehand and we'll review it together as a group, live on stage. Expect honest feedback, fresh perspectives, and plenty of "ah, that's how you could do it" moments. This time we are hosted by **c-base** (Rungestrasse 20 10179 Berlin). Come by and enjoy an evening of learning, networking, and socializing with fellow Symfony and PHP developers. **Agenda:** 18:30: Doors open 19:00: Welcome and Introduction 19:20: **Part 1: "Live Code Review - Bring Your Own Code"** **by Stefan Priebsch & Sebastian Bergmann** 19:50: Break & Snack 20:00: **Part 2: "Live Code Review - Bring Your Own Code"** **by Stefan Priebsch & Sebastian Bergmann** 20:40: Socializing **Event Details:** **"Live Code Review - Bring Your Own Code"** by Stefan Priebsch & Sebastian Bergmann When Sebastian Bergmann and Stefan Priebsch take the stage together, expect an evening focused not on theory, but on the craft of building good software. As founders of [thePHP.cc,](http://thePHP.cc,) they have influenced the conversation around code quality, testability, refactoring, and sustainable architecture in the PHP community for many years. At this Symfony User Group meeting, they bring that experience to a special format: a public code review of code submitted by attendees. Together, they will look at real-world examples from everyday development, share direct feedback on structure, readability, testability, and maintainability, and show how even long-lived codebases can be improved step by step. This is a great opportunity to see how experienced practitioners approach code, which common issues they spot quickly, and which improvements can have the biggest impact in practice. If you would like feedback on your own code, bring it along. Please make sure to remove any credentials or personal data before sharing it publicly. The feedback will be constructive, respectful, and focused entirely on improving the code. Don't miss this insightful event, engaging discussions, and networking opportunities. We can't wait to see you at the June Symfony User Group! If you have any questions or accessibility requirements, please reach out to us. Also, if your company wants to be the next host for the User Group, just let us know!

🕢 Doors open at 18:30 and sessions start at 19:00. Freestyle vocal workout at and play session. €8-20 😌 Flow is a state of being… an experience when you allow yourself to be 100% fully engaged in the present moment in a feedback loop between clarity and satisfaction. It is an undeniable sensation where things seem to be more effortless, pleasurable, in sync, and you can easily sense a connection with something greater than yourself; this is what we will create…: • a connected and mindful meditation where it is possible to blissfully surf the cutting edge of the present moment together… • a game where it’s possible to feel excited and calm in the same moment, and everyone can win as much as they like… Scott Bolden, founder of Das Baumhaus Berlin will share some very easy, practical and effective methods developed during the last 12 years of facilitating the “Improvisational Groove Orchestra” (I.G.O.) improv vocal jam sessions. Within 20 minutes participants learn to use the common sound space to create resonance in the form of improvisational music where it is quite common to experience some real flow moments… It is very easy to participate, no musical talent or training is required so anyone is welcome to join. All of the session is done with eyes closed to avoid visual distractions and keep focus on the co-created sound space. During these sessions we will also have short breaks for feedback and refreshment. Important – Please be on time. It is very important to understand the methodology and warm up in the group before joining in! 🎤 @21:00 - Freestyle vocal workshop and practice session. €8-15 Have you ever wanted to learn how to do freestyle vocalizations? Maybe you are on your way and would like to just have a fun workout session with other vocal freestyle enthusiasts. All levels welcome.

Our June Meetup is coming up! Thanks to Snowflake for sponsoring us. **Please register with your real name and email addres and bring a photo id.** You will need to check in upon entry. We are happy to have David Wheeler as our speaker this time. David is ais a long-time PostgreSQL contributor, and creator of Sqitch, a database change management system; PGXN, the PostgreSQL Extension Network; pgTAP, a database test framework, and CITEXT2, the case-insensitive data type. After stints with PostgreSQL Experts, iovation, and The New York Times, he now works on PostgreSQL extensions for ClickHouse. He lives in New York City with his artist wife when they're not exchanging homes overseas. His talk is: *How to automatically release your extensions on PGXN* Today there is no one central distribution point for PostgreSQL extensions. The largest the extension source distribution service PGXN. It contains approximately a third of all known publicly-available extensions, but even those are not all up-to-date. PGXN aims to be the root registry for all extension releases, and plans to publish all releases to allow downstream registries to automate their build processes, as well. As such, it benefits extension developers and the broader PostgreSQL community when it contains up-to-date releases of all known extensions. I'll show you the process to set up PGXN distribution for your extensions, and the tooling to automate releases to keep it up-to-date. The main things to understand are Git, JSON, and GitHub workflows. At the end of the session, you'l have all the information you need to quickly and automatically publish your extension on PGXN.

Hello challengers, For those who missed last month’s incredibly popular Trend Color Hunt Challenge, I’ll be hosting the workshop again due to high demand. In this workshop, we’ll go beyond simply taking photos, we’ll train your eye to see color with intention and use it as a powerful storytelling tool. Instead of focusing on subjects alone, this challenge invites you to explore Berlin through a single lens: **color**. You’ll be split into small groups and assigned a specific color. Your mission is to hunt for it, frame it, and bring it to life through a series of images. By the end, each group will become the storyteller of their color across the city. Along the way, you’ll learn how to use color not just as an aesthetic, but as a way to guide attention, create emotion, and build stronger compositions. Learn to see, compose, and tell stories through color using contrast, simplicity, and creative interpretation. 🧠 **How the Challenge Works** * You’ll be split into groups of **2–3 people** * Each group is assigned **one color** * You’ll have **\~60 minutes** to explore and shoot * Your goal: capture a small series of images that represent your color in Berlin **A Social Experience** As much as this is a photography group, it’s about connection and community. Within your group, you’ll collaborate, explore, and share perspectives. Whether you’re experienced or just starting out, this is a space to meet creatives that can learn from each other. 🎒 **What to Bring** • Your Camera – DSLR, mirrorless, or smartphones are allowed • Comfortable Clothing – We’ll be walking and exploring • Curiosity and open mindedness – Be ready to observe differently and go out of your comfort zone and challenge yourself! I’ll also compile the results into curated series like: **“Berlin in Red” \| “Berlin in Green” \| “Berlin in Blue”** Selected photos will be featured on our Instagram community. 💸 **Cost** **€10** – collected after the session or pre-pay via PayPal to secure your spot. Maximum limit of 55 participants. 🌱 **Why Join?** ✅ Experience Berlin in a completely new way ✅ Learn how to use color as a storytelling tool ✅ Build confidence shooting in real environments ✅ Meet and connect with creatives in Berlin ✅ Get featured in our growing photography community 🎁 **Exclusive Benefits for Donors** • Private WhatsApp Group Access • Instagram Features • Personalized Feedback • Bonus Meetups • Resource Library (tips, recaps, guides) 📷 WhatsApp Group: [https://chat.whatsapp.com/LxEb41NmxyK4oRJeM9o2KW](https://chat.whatsapp.com/LxEb41NmxyK4oRJeM9o2KW) 💸 Donate: [https://www.paypal.com/donate/?hosted_button_id=W77YS88G5W8ZL](https://www.paypal.com/donate/?hosted_button_id=W77YS88G5W8ZL) 📸 Instagram: [https://www.instagram.com/berlinphotochallenge](https://www.instagram.com/berlinphotochallenge)

**Rust Berlin on location 🏳️‍🌈** is a new, informal in-person Rust meetup group in Berlin. We are a interactive meetup format interested in mob coding, deep diving and problem solving together. We build toy projects, share experiences, discuss technology and learn new cool stuff. And you are welcome to join! No matter if you are writing Rust production code every day, if you already contribute to Open Source projects or want to start doing so, if you use Rust in hobby projects or if you are just curious what the hype and buzz is all about, you are very welcome! To coordinate and plan activities, please join our **[Rust Berlin on location 🏳️‍🌈](https://rust-berlin.zulipchat.com/join/gap4pdbz7xsquliiz7tgcyuk/)**[ Zulip chat](https://rust-berlin.zulipchat.com/join/gap4pdbz7xsquliiz7tgcyuk/)! **Planned programme** Being an informal meetup, we are open to anything between just meet and talk, explore nerd snipes and rabbit holes, mob code together, plan and build fun projects, tinker with electronics, and presentations with Q&A. With the [introduction](https://berline.rs/2026/04/01/berlin-talks.html) of the new [Rust Berlin Talks](https://berline.rs/about#rust-berlin-talks) meetup series, **[Rust Berlin on location 🏳️‍🌈](https://berline.rs/about#rust-berlin-on-location)** strengthens its focus on social community experience, the exchange of knowledge, ideas and perspectives, and the joy of spontaneity. This time, Florian Gilcher will give a small **workshop on structured and safe usage of *\`unsafe\`***. We will look at some common use-cases and how common hazards can be avoided. Anyone is invited to bring their projects and questions, show something, ask something, or explore a topic together. The best conversations and deepest rabbit holes can emerge out of seemingly nowhere. **Projected upcoming meetups** We schedule regular meetups on Thursday evening every four weeks, using the slot between the Berlin Rust Hack and Learn online meetup (every two weeks), and the Rust Nuremberg online meetup (every four weeks). 11 June 2026 is our fourteenth meeting Our next projected meetings are going to occur on the following dates: * 9 Jul 2026 * 6 Aug 2026 * 3 Sep 2026 * 1 Oct 2026 * 29 Oct 2026 * 26 Nov 2026 **Location** Our meetup location is the new shared office community space of Ferrous Systems, Slint and KDAB in Berlin Mitte, for up to 25 people. We are expecting to use this space as our default location for the time being, with the IN-Berlin e.V. community space in Moabit as backup. Regardless, as our group might eventually outgrow the locations' size limit, we are low-key looking for bigger locations. If you know a fitting location, then please let us know in our Signal group! Another workable way might be to split the meetup into smaller, interest-specific sub-groups instead. As the no-show rate on Meetup.com is rather high, consider showing up even if you are on the waiting list. We can't promise that there is any space left, but usually there is. So give it a shot! **Accessibility** The location has an elevator and a wheelchair accessible bathroom. Please note that the bathroom is two floors down from the meetup space. On our quest for a bigger location, we are going to pay special attention to accessibility. **Community** We aim to create a safe place for everyone and adhere to the [Berlin Code of Conduct](https://berlincodeofconduct.org/). Inclusivity is very important to us. If you are curious about Rust, but unsure if you are welcome to join: Yes, yes you are. Please come to the meetup! If you have special needs, please get in contact, we will try to accommodate you as best we can. We are part of [https://berline.rs/](https://berline.rs/) and like to hang out in the **[Rust Berlin on location 🏳️‍🌈](https://rust-berlin.zulipchat.com/join/gap4pdbz7xsquliiz7tgcyuk/)**[ Zulip chat](https://rust-berlin.zulipchat.com/join/gap4pdbz7xsquliiz7tgcyuk/). You are very welcome to join!

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD
