Check it out 👇 ────────── **18:30: Welcome** Grab a seat until everybody arrives! **18:45 Intro by Hosts Neciu Dan & Erik Grijzen** **19:00 8 Years of Micro Frontends @ New Relic: Lessons Learned** Speaker: **Erik Grijzen, Principal Software Engineer** New Relic started implementing a Micro Frontend architecture about eight years ago, before the concept of Micro Frontends even existed as an architectural pattern. Over the years, we’ve learned hard-won lessons on designing, scaling, and maintaining Micro Frontends. We will go over some of the most important architectural decisions that need to be considered and see how they have affected us. We will also cover some of the most common anti-patterns and discuss practical strategies to avoid them, illustrated with real-world examples. **19:30** **Developing a micro-frontends open source framework** Speaker: **Natalia Venditto, Engineer and hands-on architect at Adobe** In this talk, I will talk about the technical challenges of building and maintaining an open source framework. What features we have prioritized while using it and solving real life problems, how we have monkey patched the browser to work on top of the web platform and make it agnostic and how we are working to port some of those features as standards **19:50: Drinks and networking!** Do you want to talk at this meetup?

⭐ ¡¡ATENCIÓN, SOLO POR ESTA SEMANA NOS VEMOS EL MIÉRCOLES!! ⭐ Hola, soy Valentina ✨ Quiero compartir contigo un espacio gratuito y sagrado de encuentro, empoderamiento y expansión entre mujeres. Un lugar donde poder conectar y conocer nuevas personas, creando vínculos profundos desde la amabilidad, el respeto, la alegría, el disfrute y el compartir auténtico. Un espacio seguro y amoroso donde expresar nuestra sensibilidad más genuina, reconectar con nuestra feminidad y empoderarnos entre todas. Deseo que este sea un espacio creativo, vivo y nutritivo, donde cada encuentro sea diferente. En cada reunión os iré proponiendo herramientas, rituales, ejercicios, dinámicas o simplemente una conversación abierta y sincera, desde el corazón y la presencia. Un círculo donde poder sentirnos vistas, escuchadas y acompañadas. Donde celebrar quienes somos, sostenernos mutuamente y tejer una red femenina consciente y bonita. Y por favor, que no te dé reparo o vergüenza sumarte al encuentro. Eres bienvenida, así, tal y como eres, con todo lo que traes contigo ese día. Siempre vas a estar bienvenida 🌙 Y si te apetece traer algo para compartir —una infusión, fruta o algo rico para picar— será siempre bienvenido. Intentaremos que sean opciones saludables para disfrutar entre todas 💛 📍 Nos encontramos cada lunes de 19:00 a 20:30 en Poblenou, Carrer de Taulat 71, bajo 1. 📞 Por favor, confirma tu asistencia al número: +34 656 737 190. ✨ **¿Quieres recibir más información?** 🌿 Sígueme en Instagram: **@rendirse_al_amor** 💬 Únete al grupo de WhatsApp para estar al día de los próximos encuentros: [https://chat.whatsapp.com/BrlB5pAHs6iAzarn9VrScf?utm_source=chatgpt.com](https://chat.whatsapp.com/BrlB5pAHs6iAzarn9VrScf?utm_source=chatgpt.com) Os comparto mi recorrido vital para que me podáis conocer un poquito más y sentir el tipo de energía que acompaña estos encuentros: Me formé como pianista clásica y trabajé durante muchos años como artista y profesora de piano en Italia, mi amada tierra natal. A los 24 años sentí que mi vida se había vuelto demasiado estrecha, como si viviera en una jaula que no me reflejaba, y comencé a buscar un camino más amplio y verdadero para mí. Esa búsqueda me llevó a recorrer medio mundo durante los últimos 15 años. Empecé en Estados Unidos formándome como Master Avatar, un proceso profundo de exploración de la conciencia, las creencias y los condicionamientos, hasta reconocerme como creadora de mi propia realidad. Después llegué a las constelaciones familiares del espíritu, donde me formé como consteladora, y que desde entonces se ha convertido en una filosofía de vida para mí, que podría resumir en una sola frase: rendirse al amor. A través de ese camino llegué a México y al mundo chamánico, que me abrió el corazón a una percepción mucho más amplia de la realidad. Más adelante llegaron la meditación, las meditaciones activas de Osho, los masajes, el tacto consciente y herramientas de desbloqueo emocional como el Código de la Emoción y el trabajo con el cuerpo. En este recorrido también he integrado la nutrición celular como pilar para el bienestar integral y cuidado del cuerpo. Mis viajes me han llevado de forma recurrente a México durante los últimos diez años, donde continúo visitando a mi maestro Nawal Tata Kachora. También he vivido experiencias profundas en la selva amazónica, en procesos de depuración con las plantas medicinales y los chamanes de esa tierra. He pasado también por la India y algunos de sus lugares más sagrados, nutriéndome de su sabiduría ancestral. He recorrido muchos caminos y formas de vivir la vida. Y si hay algo que hoy tengo claro es que todo forma parte de mí. Mi misión en este mundo es reunir lo que se separó y traer una mirada de amor y reconciliación a este mundo.

No slides. No speaker. No agenda. Just developers talking shop over a cold one. This is an informal gathering for engineers, founders, and builders who are deep in the agentic coding trenches — using tools like Cursor, Windsurf, Claude Code, OpenCode, or rolling their own agent pipelines. Come swap what's actually working, what blew up in production, and what you're excited about right now. We'll be at Barcelona, and the format is simple: show up, grab a drink, and share what you know. Bring a laptop if you want to show something, but it's not required. WhatsApp Group: https://chat.whatsapp.com/GVS0bHMPIzID3Ch9lt6YsU?mode=gi_t **What we talk about (but not limited to):** \*Agentic coding workflows and tooling * Prompt engineering & context engineering in practice \*Multi-agent architectures and orchestration * AI-native product building \*What's broken in the ecosystem and how you're working around it **Who should come:** Developers, technical founders, and AI engineers who build with (or on top of) LLMs. All levels welcome — senior devs with war stories and curious beginners both make the conversation better. **Format:** Open conversation, round-table style. Everyone teaches, everyone learns.

Aleix Pol, president of [KDE e.V.](https://ev.kde.org/) will talk about [BuildStream](https://buildstream.build/), a mechanism to build operating systems and all sorts of packages like that. We will discuss why it's interesting, what can it do and why have I been spending time seeing to [KDE Linux](https://linux.kde.org/) using it as it's build tool. After this presentation you'll also know how to build your operating system and hopefully be able to contribute to a bunch more! 📅 **Date:** 11 June ⏰ **Start time:** 19:30 h 📍 **Location:** [Akasha Hub](https://maps.app.goo.gl/CZE8q8uaag8UgnRCA) \- Carrer de la Verneda\, 19\, Nau 1 · Barcelona

**“¿Cómo conseguimos grandes diseñadores? Los grandes diseñadores diseñan, por supuesto.”** *Fred Brooks* **“Entonces, ¿cómo se supone que vamos a conseguir grandes arquitectos si solo tienen la oportunidad de ser arquitectos menos de media docena de veces en su carrera?”** *Ted Neward* ¡Estamos de vuelta con otra [kata focalizada en diseño de sistemas](https://www.architecturalkatas.com/)! 🎉 ¿Qué es una [kata de arquitectura](https://continuous-architecture.org/docs/rituals/architecture-kata.html)? En pocas palabras, los katas de arquitectura son ejercicios diseñados para maximizar el esfuerzo en arquitectura, minimizar los costes innecesarios y completar todos los elementos críticos que un ejercicio de arquitectura debe incluir: un cliente, restricciones del proyecto, requisitos cambiantes, compañer@s y un proceso de revisión. No se requiere experiencia previa en diseño de sistemas o arquitectura. No tener experiencia puede ser incluso más beneficioso: no tendrás ideas preexistentes sobre cómo “debería” hacerse. *El idioma principal será el 🇪🇸 y podemos acomodarnos al 🇬🇧 según asistentes.* **📅 Agenda** * 18:30-18:45. Bienvenida de [eDreams ODIGEO](https://www.edreamsodigeo.com/es/). * 18:45-20:00. Introducción breve a la kata, **cell-based architecture** **y sus diferencias con microservicios**. Después trabajaremos en grupos pequeños, de 3 a 5 personas, sobre un escenario ficticio pero realista que revelaremos durante el evento. Finalmente, pondremos en común las soluciones propuestas. * 20:30-21:00. Networking. **🙇‍♀️ Facilitan** [Anyul Rivas ](https://es.linkedin.com/in/anyulled/es)\- Senior Solutions Architect en GFT\. **🏢 Dónde** 🆕 eDreams ODIGEO: [Carrer Bailèn, 67-69, Barcelona](https://maps.app.goo.gl/fUHS4AtZGf6D9UoL8) *Si tenéis problemas para llegar o acceder, contactad a través de comentarios en el meetup.* Queremos agradecer a nuestro sponsor, [eDreams ODIGEO](https://www.edreamsodigeo.com/es/) 🙌, por facilitarnos el espacio, snacks y refrescos 🍲 🍕 🍴🥤🧃 ¡Nos vemos allí!

Long Live the Silo.](https://uxdx.com/session/the-silo-is-dead-long-live-the-silo/) This talk explores how AI is reshaping ownership, craft and collaboration in cross-functional teams, and why the specialists who feel most threatened might actually be the ones who matter most. Expect honest observations and some uncomfortable questions. **Talk by Mert Tas -** [AI, Collaboration, and Hidden Tradeoffs of Product Teams](https://uxdx.com/session/ai-collaboration-and-hidden-tradeoffs-of-product-teams/) Generative AI is changing how product, design, and engineering teams work together, from how ideas are explored to how decisions are discussed and documented. In this session, Mert will share practical experiences from working on complex design and personalization products at Vistaprint: where AI genuinely improves quality, shared context, and speed, and where it risks creating shallow alignment, coordination overhead, or endless artifact generation instead of deeper thinking. The session is intended less as a prescription and more as an honest reflection on the new collaboration tradeoffs many teams are already starting to feel. ## **About UXDX** UXDX helps teams shift from project based delivery to empowered, autonomous product teams. We host global conferences and over 150 free community events each year, bringing together UX, Product, Design and Development practitioners to share how real teams build better products faster.

**The event has been canceled.** *Note: this is a demonstration event only, you **will not** shoot you own images. However, if you bring your camera we can test it for compatibility with the studio lights.* Bondage elements can add an extra layer of emotion and artistry to your images. Sample images on the internet are however dominated by BDSM style shots that are often sexualized and emphasize the model being in distress. In this demonstration Rachel and I show ways to use bondage elements in an artistic way. We explore the types of accessories that work best in artistic images and the best way to photograph them. Our model is Rachel Adams, an internationally known fetish model with many years of experience in this genre.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** *Customize the IDE: Building Extensions for Visual Studio Code* Visual Studio Code is one of the most widely used development environments today, and much of its flexibility comes from its extension ecosystem. 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
