Volvemos a la carga con mucho teatro y más ganas que nunca de poder compartir este maravilloso arte con vosotros. Teatro en estado puro al alcance de todos! El nivel inicial tiene una gran importancia en el camino del desarrollo teatral, ya que en este primer contacto con el teatro nos basamos en comprender el hecho teatral en sí. Para ello realizamos una formación actoral básica, basándonos en las técnicas y disciplinas básicas de las artes escénicas, así como en los conocimientos indispensables para cualquier actor. Trabajo de improvisación, voz, expresión corporal, paleta emotiva, escenas, creación y trabajo de personajes, creación propia, desbloqueos etc. Siempre trabajando de una manera lúdica, el alumno podrá investigar las distintas herramientas escénicas que se pueden dar en el espacio teatral, mejorar la expresividad, potenciar la creatividad, el trabajo en grupo, la autoestima, y mucho más. Tomará conciencia de su cuerpo, del espacio, aprenderá de forma práctica como es la relación con los objetos, la creación de personajes y el trabajo de la improvisación, mejorando la expresión corporal y oral. Pero sobretodo DIVERTIRSE HACIENDO TEATRO, ese es nuestro principal objetivo. No os preocupéis si no hay mucha gente apuntada por meetup, la actividad se hace igual porque tenemos más gente apuntada por otros lugares.

April Meetup is here! 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! **18:45 Intro by Host Neciu Dan** **19:00 Type safety across the network chasm** Speaker: [Alexander Vechi](https://www.linkedin.com/in/alvechy/), Product Engineer at SkyScanner Type safety often stops at the network boundary. In this talk, Alex will look at how modern frameworks try to bridge that gap, and share lessons from Skyscanner’s setup with protobuf-generated TypeScript types, including versioning, nullability, and validation to make API contracts safer in real frontend code. **19:25** **Building a Workflow Builder From The Ground Up** Speaker: [Martí Serra Molina](https://www.linkedin.com/in/ACoAADubmLMBJy_b_UNaB8Za17gbj1sc69JgkcY/?lipi=urn%3Ali%3Apage%3Ad_flagship3_profile_view_base%3BBKaAifpsSFG5%2BC062yD%2Blw%3D%3D) Frontend Engineer \| Creator of Formity Workflow builders are powerful tools for visually designing and automating complex processes, but building one from scratch in React poses unique challenges. Most teams reach for React Flow to handle node-based diagram rendering, yet there is still significant logic to build on top of it — a node layout algorithm, workflow state modeling, drag-and-drop, undo and redo, and more. In this talk, you will learn how to build a workflow builder from the ground up and the real-world complexities that emerge along the way. **19:50: Drinks and networking!** Do you want to talk at this meetup? Reach out to Dan Neciu [on LinkedIn](https://www.linkedin.com/in/neciudan/) And please help us spread the news and grow the community: **20:55 Meetup finished** **(FOR EARLY ACCESS: WE ALWAYS POST FIRST ON SOCIAL MEDIA)** [Twitter(X)](https://x.com/ReactJsBCN) [BlueSky](https://bsky.app/profile/reactbarcelona.bsky.social) [LinkedIn](https://www.linkedin.com/company/reactjs-barcelona/) [Instagram](https://www.instagram.com/reactjs_barcelona/) ────────── **Sponsors:** Skyscanner 🌎 We're here to help every traveller explore the world effortlessly, with a vision to become the world's number one travel ally. ────────── **Join the Master Security Course for FREE!** Modules 1 & 2 are live now — **Exploits and XSS** — completely free to access. * Understand how common vulnerabilities actually work * Learn to identify and prevent security flaws in your code * Get practical, real-world examples you can apply immediately * Types of XSS + real case studies of XSS in ReactJS and more This is just the beginning — start building security expertise today.

🔧 Join us for **two talks** focusing on **getting more out of PHP** without unnecessary complexity, from async execution to performance insights. Stay for **discussion, drinks, and snacks** afterward. **Details** ⏰ Aptil 9th 🗓 Starting 6:30 pm 🇬🇧 Talks in English 🎟 Free 📍NN Working. Carrer de Pau Claris, 194, L'Eixample, 08037 Barcelona (4th floor) **Talks:** **1\. Topic:** **PHP Fibers: simplifying async code and speeding up development** **Speaker:** [Max Fomichev](https://www.linkedin.com/in/maxim-fomichev/), Infrastructure Engineer at Manychat **About the Talk** We constantly search for creative ways to get maximum out of php, without bringing excessive complexity for our developers daily work. In this speech I'll sum up our way, describe where are we now in a bit, and share how we started to use fibers and asynchronous http requests to speed up both our code writing and execution, while avoiding excessive cognitive load for our developers dealing with "asynchronous" programming. **About the Speaker** Max has decades of experience in IT, primarily focused on programming in PHP and running Unix servers. For the past six years, he has been working at Manychat, a leading chat-marketing platform, where I combine the roles of an Infrastructure Engineer, SRE, and developer, optimizing systems and ensuring reliability. **2\. Topic:** PHP Performance Demystified - Measure, Understand, Optimize **Speaker:** [Volker Dusch](https://www.linkedin.com/in/volker-dusch/), Head Of Engineering at Tideways, PHP 8.5 Release Manager **About the Talk** In this talk, we'll explore options for PHP performance analysis. From understanding how the PHP virtual machine and OPCodes work, to performing your own reliable and meaningful benchmarks, and how to use request profiling using open-source and commercial offerings. You will leave with an overview of the available tools and an understanding of how to use them in your day-to-day. Learning how to spot bottlenecks and optimize them away efficiently and confidently. **About the Speaker** With over 20 years of software development experience, Volker has seen PHP grow and mature from PHP 3, working on long-living custom applications in high-traffic environments. From social networks to medical data processing, he has worked as an engineer, team lead, and Head of Engineering, mostly focusing on PHP, Go, C, JavaScript, HTML/CSS and System Operations. https://phpc.social/@edorian **Thanks to Manychat to host the meetup** – [Learn more](http://%5Bhttps/%5B%5Bmedium.com/manychat-engineering%5D%5D%5D(%5Bmedium.com/manychat-engineering%5D%5D)(%5Bmedium.com/manychat-engineering%5D%5D(medium.com/manychat-engineering%5D))(https:/%5B%5Bmedium.com/manychat-engineering%5D%5D(%5Bmedium.com/manychat-engineering%5D)(%5Bmedium.com/manychat-engineering%5D(medium.com/manychat-engineering)))) about Manychat Engineering – [Careers](http://%5Bhttps/%5B%5Bcareers.manychat.com/%5D%5D%5D(%5Bcareers.manychat.com/%5D%5D)(%5Bcareers.manychat.com/%5D%5D(careers.manychat.com/%5D))(https:/%5B%5Bcareers.manychat.com/%5D%5D(%5Bcareers.manychat.com/%5D)(%5Bcareers.manychat.com/%5D(careers.manychat.com/)))) at Manychat – [Videos](http://%5Bhttps://www.youtube.com/playlist?list=PLIfURI1S1wkA2sVy_AYtJcR_HyBpsTa2d%5D(https://www.youtube.com/playlist?list=PLIfURI1S1wkA2sVy_AYtJcR_HyBpsTa2d) "\[https://www.youtube.com/playlist?list=PLIfURI1S1wkA2sVy_AYtJcR_HyBpsTa2d\](https://www.youtube.com/playlist?list=PLIfURI1S1wkA2sVy_AYtJcR_HyBpsTa2d)") from the previous meetups

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD
