Together with Capgemini, we’d like to invite you to our talk in June. This time, we’ll be discussing spec-driven development with Simon Martinelli. **Spec-Driven Development in Practice: How AI Simplify Full-Stack Java** AI is transforming how we develop software, but many teams still treat code as the source of truth, leading to outdated documentation and hidden business logic. What if specifications became the single source of truth instead? This session introduces Spec-Driven Development (SDD) and the AI Unified Process (AIUP), a practical approach in which developers write clear, structured requirements, and AI generates everything else: diagrams, code, and tests. When requirements change, the system stays consistent automatically. Based on a real-world Java project built with Spring Boot, jOOQ, and Vaadin, the most productive and secure web framework for Java, you’ll see how SDD keeps business rules, data access, and UI perfectly aligned. Join this session to learn how AIUP helps Java developers deliver applications faster, with less boilerplate and more focus on what really matters: understanding the domain. Most teams still treat code as the source of truth, leading to outdated documentation and hidden business logic. In this session, you’ll learn how Spec-Driven Development (SDD) and the AI Unified Process (AIUP) let you define requirements once and generate consistent Java code, diagrams, and tests automatically. Based on a real project with Spring Boot, jOOQ, and Vaadin, this talk shows how to build faster, safer, and more maintainable full-stack Java applications. **Simon Martinelli** Simon Martinelli is a Java Champion, Vaadin Champion, and Oracle ACE Pro with over three decades of experience as a software architect, developer, consultant, and trainer. He is the creator of the AI Unified Process (AIUP) and a strong advocate of Spec-Driven Development. As the owner of Martinelli LLC, he coaches teams to get up to speed with AI-driven development. He regularly shares his insights through international conferences, articles, and his blog, Keep IT Simple (https://martinelli.ch), where he writes about AI, architecture, and modern Java development. He is also a lecturer at two universities in Switzerland, where he teaches software architecture, persistence, DevOps, and cloud-native development.

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)

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!
