Second Meetup in April OMG!!! Let's gooo! We have some amazing speakers, and of course, pizza and drinks will be available after the event. ────────── **18:30: Welcome** Grab a drink and a seat until everybody arrives! **18:50 Intro by Host Neciu Dan** **19:00 Front-end testing at Preply: Shifting left towards component testing with Storybook** Speakers: Lukasz Rados and Dominika Szukala, both Senior Frontend Engineers at Preply Preply invested a lot into E2E testing in the past, but this approach wasn’t scaling well for us. With the advent of the company rebrand and the new engineering excellence culture, Preply needed a new approach to front-end testing. We (Dominika and Lukasz) embarked on a project to apply the new Engineering Excellence principles to front-end testing, providing the tools and fixing the current context to steer the whole company toward component tests. **19:25** **AI vs. App Engineer. Claude vs. Stack Overflow,** **or How an Animation Task Can Change the Perception of Your Work** Speaker: Arthur Repin, App Engineer at Preply I had a task, that initially looked like a routine change. Normally, I would handle it the usual way: check the documentation, browse Stack Overflow, try a few naive solutions, iterate, and get it done. But not this time. This is a story about how a wrong estimate can actually pay off later by saving time on future tasks. It’s a journey through misjudged effort, shifting approaches, unexpected struggles, and the lessons learned along the way. It also includes a deep technical dive into React Native animations, exploring complex animation patterns and why achieving smooth performance, especially on Android, is still a challenge. This talk is for engineers who want a deeper understanding of React Native animations and a reminder of why engineers still matter in the age of AI. **19:50: Drinks and networking!** Do you want to talk at this meetup?

Music has always shaped human emotion. Long before streaming platforms, people understood that music could influence the way we feel, think, and interpret the world. What is new is the scale, speed and precision with which artificial intelligence is beginning to intervene in that relationship. **[TICKETS MUST BE PURCHASED HERE VIA LUMA - FROM 9 EUROS](https://luma.com/snz5y934?UTM-SOURCE-MEETUP)** ​In this Growth Lab LIVE session, hosted by composer and AI educator Rafel Jaume I Venys, we explore how AI-driven systems, from recommendation engines to generative music platforms, are learning to analyse emotional patterns, predict responses and create feedback loops in which feeling becomes data, and data becomes influence. ​As these systems become more sophisticated, music is no longer just something we choose or consume. It is increasingly something shaped around us indvidually, designed to hold attention, steer mood and optimise emotional response. ​Drawing on the myth of Orpheus, this session examines the rise of an algorithmic orchestra: a new technological force capable of conducting human emotion without ever experiencing it. The question is no longer whether AI can compose music, but what it means to live in a world where the systems shaping our inner lives may understand our responses better than we do ourselves. ​About the speaker: ​​**Rafel Jaume i Venys** is a composer, philosopher, and educator working at the crossroads of music, AI, and ethics. He’s the founder of **CAIRAI**, a consultancy focused on AI, education, and social impact, and lectures at several universities. His work bridges critical thinking and creative practice, helping individuals and organizations harness AI in ways that are both innovative and humane.

**Bueno, bueno, bueno…¡primer evento ON**! 🎉 (english version below) Estamos encantados de poder anunciar para el próximo 29 de abril el primer evento de **Claude for Everyone Barcelona**. Arrancamos con muchas ganas y mucha ilusión por poder crear un punto de encuentro para compartir, conectar, intercambiar ideas y explorar juntos lo que hay y lo que viene dentro del campo de la inteligencia artificial. Queremos dar mil gracias a nuestro anfitrión, 🙌 **Plain Concepts** 🙌, por facilitarnos el espacio, snacks y refrescos en esta ocasión tan especial! #**Love** 📅 **29 de abril** \| Apertura de puertas a las 18:00h\, empezamos a las 18:15h 📍 **Plain Concepts** \- Carrer del Comte d'Urgell\, 240\, 6B\, Eixample\, 08036 Barcelona **Agenda** ➡️ 18:00 - 18:15 — Check-in 🏢 18:15 - 18:30 — Presentación de nuestro anfitrión y de la comunidad 🎤 18:30 - 19:15 — *De cero a Jazzucrist: O cómo la IA me salvó de ver otra serie mala en Netflix*, por Manel Vericat 🎤 19:15 - 20:00 — *El efecto AI-Express: lo que pediste vs lo que te llega* , por Maite Malavia 🧃 20:00 - 21:00 — Networking \*\*\* 🎙️ **Charlas** **De cero a Jazzucrist: O cómo la IA me salvó de ver otra serie mala en Netflix** ¿Qué pasa cuando una idea que hace años era técnica y económicamente imposible se cruza con la tecnología de hoy? En esta charla exploraremos cómo la Inteligencia Artificial ha cambiado las reglas del juego para los creadores individuales. A través del caso real de Jazzucrist —un proyecto completo construido desde cero por una sola persona integrando un stack profesional, demostraremos que el límite ya no es el código, el equipo ni el presupuesto, sino nuestra propia ambición. Lo que antes requería agencias enteras y meses de desarrollo, hoy es una realidad tangible. La IA nos da el poder de construir lo que imaginemos. El futuro ya no se parece en nada a lo que pensábamos ayer. La pregunta es: ¿Sigues prefiriendo una mala serie Netflix o llevar a cabo tu proyecto? *Por Manel Vericat, AI & Data Trainning Specialist* \*\*\* **El efecto AI-Express: lo que pediste vs lo que te llega** Esta charla es un recorrido por la brecha entre las expectativas que se generan, LinkedIn mediante, alrededor de la IA y los resultados que vemos en el día a día de muchas organizaciones. Con un enfoque directo y con algo de humor, hablaremos sobre esa narrativa de la “transformación IA” como un cohete mágico impulsado por datos perfectos y slides brillantes. También hablaremos sobre aquello que frena las iniciativas y qué diferencia a los equipos que sí están aprovechando la IA para generar impacto y construir valor de verdad. En resumen: una mirada honesta a lo que hay detrás del hype mediático y a lo que realmente funciona a día de hoy. *Por Maite Malavia, AI Trainning Consultant & Solutions Architect* \*\*\* ⚠️ El aforo es de **60 plazas**. Te recomendamos reservar la tuya cuanto antes. Si finalmente no puedes asistir, por favor avísanos con antelación para liberar tu plaza. **¡No te lo pierdas, te esperamos**! 🎉 \-\-\-\- **Well, well, well… first event ON!** 🎉 We’re excited to announce the very first **Claude for Everyone Barcelona** event, happening on April 29. We’re kicking things off with lots of enthusiasm and excitement to create a space where we can share, connect, exchange ideas, and explore together what’s happening — and what’s coming — in the field of artificial intelligence. We also want to give a huge thank you to our host, 🙌 **Plain Concepts** 🙌, for providing the venue, snacks, and refreshments on this special occasion! #Love 📅 **April 29th** \| Doors open at 18:00\, we start at 18:15 📍 **Plain Concepts** – Carrer del Comte d'Urgell, 240, 6B, Eixample, 08036 Barcelona **Agenda** ➡️ 18:00 - 18:15 — Check-in 🏢 18:15 - 18:30 — Host and community introduction 🎤 18:30 - 19:15 — *From zero to Jazzucrist: Or how AI saved me from watching another bad Netflix show*, by Manel Vericat 🎤 19:15 - 20:00 — *The AI-Express effect: what you asked for vs. what you actually get*, by Maite Malavia 🧃 20:00 - 21:00 — Networking *** 🎙️ **Talks** **From zero to Jazzucrist: Or how AI saved me from watching another bad Netflix show** What happens when an idea that was once technically and economically impossible meets today’s technology? In this talk, we’ll explore how Artificial Intelligence has changed the game for individual creators. Through the real case of Jazzucrist — a full project built from scratch by a single person using a professional-grade stack — we’ll show that the limits are no longer code, team, or budget, but our own ambition. What once required entire agencies and months of development is now a tangible reality. AI gives us the power to build whatever we can imagine. The future no longer looks anything like what we thought yesterday. The question is: do you still prefer a bad Netflix show, or are you ready to build your own project? *By Manel Vericat, AI & Data Training Specialis*t *** **The AI-Express effect: what you asked for vs. what you actually get** This talk explores the gap between the expectations created — often via LinkedIn — around AI, and the results we actually see in many organizations’ day-to-day operations. With a direct approach and a touch of humor, we’ll talk about the narrative of “AI transformation” as a magical rocket powered by perfect data and shiny slides. We’ll also look at what slows initiatives down and what sets apart the teams that are truly leveraging AI to create real impact and value. In short: an honest look behind the hype and what actually works today. *By Maite Malavia, AI Training Consultant & Solutions Architect* *** ⚠️ Capacity is limited to **60 spots**. We recommend reserving yours as soon as possible. If you can’t attend, please let us know in advance so we can free up your spot. **Don’t miss it, we’re looking forward to seeing you there!** 🎉

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.

*Please Always contact me by whats app to book your space at the workshop, thank you!* What we' ll do You don't need to be an artist to join my creative art workshop! I'll be waiting for you outside the MACBA (The Barcelona Museum of Contemporary Art). From there, we'll take a walk to CCCB (The Centre de Cultura Contemporània de Barcelona), which has a café and co-working space. Once we get there, we'll ask for coffee/tea and get ready to embark on our creative journey! The art-making process will serve as a bridge for social and creative communication, and the theme will be centered around traveling and the things that make us vibrate. We'll start by using imagery, storytelling, and moving freely between drawing and writing to collage. We'll also work collaboratively, with each collaborator adding to a composition in sequence, allowing creativity to flow as we play. The main objective is self-expression, awakening creativity, having fun, and sharing a nice time together while colors and words come together to empower the artistic experience. I will guide you in the right direction to create something that you may have never thought of on your own, and you can take your own pace with art and bring it back home. The aim of this art workshop is to enhance your own creativity and self-expression. I will provide all the art materials, and the cost is 25 euros for a maximum of four people for a one-hour-long session. An individual session costs 40 euros. If you'd like to attend an creative art workshop please send me a message or call me to book your place. You can also arrange a different time that suits you better. Thank you very much!
