Enterprise 2.0

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Java** AI is transforming how we develop software, but many teams still treat code as the source of truth, leading to outdated documentation and hidden business logic.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 Most teams still treat code as the source of truth, leading to outdated documentation and hidden business logic.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.

It's completely free, and always will be. It's open, inclusive and Terrible. We usually play on Astro (artificial grass) and sometimes on grass, depending on numbers.

!!! Please note that this meetup will be held entirely in German only !!! Weil es bei den letzten Malen so schön war, treffen wir uns diesmal wieder im **CI Space auf der Bugenhagenstraße 9, 10551 Berlin** (https://maps.app.goo.gl/dXaYKm8fkhBsxk42A). Vielen Dank an Iztok Petek, den Inhaber vom CI Space (www.facebook.com/cispaceberlin), der das wieder kostenlos für uns möglich macht - bitte dankt es ihm nach Möglichkeit mit dem Kauf von 1, 2 Getränken vor Ort. **Bitte seid spätestens 5min vor 9 Uhr da, da wir pünktlich starten werden.** Die ersten sind i. d. R. bereits ab 8:30 Uhr da, um vorab schonmal ein bisschen durchzustarten mit dem Netzwerken. Denkt daran **genügend Visitenkarten,** bitte mindestens eine, mitzubringen für die moderierte Netzwerkrunde - nur wenn man euch kontaktieren kann, kann man euch im Nachgang auch empfehlen! ;) **Veranstaltungsort:** CI Space (Berlin-Moabit) Bugenhagenstraße 9 10551 Berlin Nächste **U-Bahn-Station**: U9 Turmstraße oder U9 Birkenstraße (jeweils ca. 5 Gehminuten). **Start:** pünktlich 9 Uhr (ab 08:30 Uhr sind die ersten meist schon da) Zum nun bereits 10. Mal verschlägt es uns nach Moabit! Unser Moderator [Der Gottwald (siehe hier)](www.der-gottwald.de) lädt erneut ein und führt euch durch den Morgen. Wie immer bieten wir eine moderierte Netzwerkrunde für euch an, um neue Kontakte zu knüpfen und das eigene Business voran zu treiben, außerdem ist Zeit für etliche weitere Gespräche! Ein ca. **10-minütiger Impulsvortrag** mit ganz viel Mehrwert für euch ist auch wieder eingeplant, diesmal kommt der von [Marcus Teschke](https://www.marcus-teschke.de/): Marcus unterstützt als selbständiger Berater, Trainer und Coach mit viel Erfahrung Führungskräfte, Teams und Organisationen. Er war zuvor 35 Jahre lang Fach- und Führungskraft bei Großbanken und ist ausgebildeter, zertifizierter Master Business Coach. Sein besonderer Ansatz ist die Kombination aus solider Coaching Kompetenz, kaufmännischer Expertise und sportlichen Wettkampferfahrungen als Ausdauersportler und Ultramarathonläufer. **Manche zukünftigen Slots für den Impulsvortrag sind noch frei:** falls ihr also bei einem zukünftigen Treffen selbst vortragen (oder gar mal ein Treffen moderieren) möchtet, meldet euch gern bei uns! Die leckeren Getränke, Snacks oder was auch immer euch zum Kauf animiert hat, bezahlt bitte selbst. \-\-\- **(Fast) alle** Gründer\*innen, StartUps, Freiberufler, Unternehmer und Unternehmensvertreter sind willkommen beim Business Netzwerken Meetup. Die Teilnahme ist generell kostenlos und **nicht** an eine Mitgliedschaft gebunden. **Bitte beachten:** Unternehmer mit Multi-Level Marketing-Geschäftsmodellen schließen wir von unseren Veranstaltungen komplett aus, da wir hier die Erfahrung machen mussten, dass es dabei oft nur ums Verkaufen geht, und meistens kein echtes Interesse am Netzwerken und am Gegenüber existiert. **Weiterhin** stehen wir deshalb auch allen Arten des Provisionsgeschäfts (Finanzoptimierer, Immobilienmakler, Versicherungsvertreter, etc.) extrem kritisch gegenüber und gestatten diesen keine Teilnahme an unseren Events. Solltet ihr der Meinung sein, ihr fallt nicht in diese Kategorie, obwohl ihr in einer der genannten Branchen arbeitet, so sprecht uns bitte im Vorfeld an. Wir freuen uns darauf, auch **dich** persönlich kennenzulernen und dir bei der Entwicklung deines Geschäfts weiterzuhelfen!

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.
