When I moved to Barcelona, I worked long hours and somehow still couldn't find people to actually practice Spanish with. ​I tried courses. I tried Duolingo and Babbel. They all felt the same: awkward exercises about topics I didn't care about, completely disconnected from my real life. ​So I figured out my own method. It worked. I learned Spanish in 4 months, and I'm now accelerating my French, not in a classroom but by integrating the language into my daily life. ​That's exactly what I'm sharing in this free 1-hour session. ​**What you'll walk away with:** * ​Why traditional methods get you stuck at the intermediate level * ​The one thing that actually moves the needle (it's not more tutoring) * ​Daily practices you can start tomorrow - built around your life, not a textbook ​**Who's this for:** * ​You've been learning a language but got stuck somewhere between A2 and B2 * ​You want to actually use the language, not spend years chasing perfection * ​You're open to rethinking how you learn ​**Logistics:** We'll meet at Sandwichez to have a Coffee all together and talk about our language experience.

## Build your personal system of AI agents ## On campus or remote live A practical intensive course for entrepreneurs, marketers, product managers, office workers, creators who want to speed up and automate their work routine with AI agents. You'll build a personal AI stack tailored to your role, then design, build, and deploy a real **AI agent** that handles your work automatically around the clock. Automate your work and save 2-3 hours per day – let the AI agents run the routine tasks for you! ## Course format * **3 evening sessions, 18:30-21:10** * **8 hours** of intensive hands-on training * Small groups (max 9 students) for personalised guidance * On campus or remote live — same experience, same price * The course is taught in **English** * **No coding experience required** * Build and deploy a **real AI agent** by the end of the course * **Industry-recognised certificate** upon completion ## Why this course is special * **You build real things from the start.** Every exercise uses your actual tasks, your brand voice, your business data — not hypothetical examples. * **You leave with a working AI agent and automated routines.** Connected to the platforms and tools you use daily it will run 24/7, handling real tasks and interactions. * **No coding required.** Master Claude Desktop to set up your personal system of AI agents without writing code. * **Role-specific from the start.** The Skills, schedules, and workflows you build are designed around what you actually do. * **Everything stays yours.** Your system, agents, course materials — everything you build is yours ready to be used after the course. ## What you will learn * Understanding **current AI tools landscape** and what they can do for your work * Writing **prompts that deliver the results you want** with prompt engineering * Master Claude Desktop * **Train Claude to understand your product** by giving it your brand voice, project knowledge base and context * **Connect Claude to all the tools and platforms** you use for work, from Google Calendar and Notion to CRM and other business applications * **Automate repeating tasks** and workflows with **your own reusable Claude commands** * **Scheduling tasks** to be run by Claude **automatically** * Creating and using **AI agents to completely automate your workflows** * A system you can **apply to any task and automate it with AI agents** right after the course ## Who should take this course? * **Marketers** * **Office workers** * **Entrepreneurs** * **Product managers** * **Creators** Automate and streamline your repetitive tasks, use AI with the voice of your brand to generate creatives, automate any type of workflow, have a personal assistant who never sleeps, analyze and report on data of any size infinitely faster than a human.

**🔎The session:** AI is already part of how we work, but most people are still using it as a chat or an autocomplete tool. The next step is moving from asking for help to letting AI actually do parts of the work for you. **That is where agents come in**. In this session, we explore **how to build and use AI agents in a practical way using tools like GitHub Copilot, Agent Mode, MCP, and reusable skills**. The focus is not on complex architectures, but on what is useful in real day-to-day work. We walk you through **what an AI agent is** and why it makes sense to use one instead of just prompts or simple automations. You will see how agents can reason, plan, and execute tasks across multiple steps, and how to apply patterns that already work in production. We also look at **how this fits into your existing workflow**, especially in environments like VS Code, and **how agents can connect to real systems and data**. Real examples will show how to automate documentation, interact with data platforms such as Microsoft Fabric, and create reusable workflows that save time. The session also **covers common mistakes**, including overcomplicating solutions with too many agents, and how to keep things simple, controlled, and maintainable. 🎯**The goal is to give you a clear and practical understanding so you can start using agents in your own work without overengineering.** 👩‍💻**This session is for you if:** * you are a developer working with code on a daily basis * you use tools like VS Code, GitHub, or similar environments * you are an engineer interested in improving productivity using AI beyond autocomplete * you want to explore how to integrate AI agents into real workflows -No prior experience with AI agents is required -Basic understanding of development workflows is enough 📋**Agenda** 🙋18:00 Registration & Welcome **🗣️18:30** Session and Q&A 🌮19:30 Drinks & Bites We look forward to this inspiring evening together! 🤩

This talk explains how recent supply-chain attacks abused that trust and what developers can do to reduce risk without stopping delivery. **19:20 Under the hood: How V8 powers your JS apps (and why you should care)** Speaker: [Gwyneth Rose](https://www.linkedin.com/in/gwyneth-rose/), Senior Engineer at Lodgify You've transpiled your JavaScript, minified it, chunked it, and sent it to your CDN. But what happens when the code actually hits the browser? In this talk, we'll walk through the workings of V8, the JavaScript engine that powers Chromium-based browsers and Node.js. We'll focus on its JIT (just-in-time) compiler, how it learns about your code at runtime, and how it optimizes for performance as you use a web app. We'll also go over concrete techniques to make the JIT compiler's job easier, helping you stay in V8's fastest execution path. **19:50: Drinks and networking!** **20:45 Meetup finished** Would you like to talk at the next meetup?

Buenas! (English below) Cada día aparecen formas nuevas de aprender español, (y otros idiomas) apps nuevas, métodos de gramática, IA, videos de profes explicando cosas, y están todas genial. Si te ayudan a entender más y a hablar mejor están genial. El plan de este grupo es mejorar tu español con juegos, actividades reales y ejercicios para hablar más. Con la excusa de los juegos y las actividades corregimos la mayoría de errores: Palabras difíciles, confundir pasados, preposiciones, verbos que significan muchas cosas, ser y estar en pasado, frases con dos verbos o mas, subjuntivo, expresiones coloquiales, y también los errores "culturales”: ¿De que forma usamos los españoles el idioma en diferentes situaciones? La gente que participa es (casi siempre) muy simpática, y normalmente deja reviews muy positivas de las clases. Si te cuadra el plan ven a practicar tu español y hablamos de comida, de viajes, de trabajo, de cultura, de Internet, de temas locales, de noticias y de muchas más cosas. Para participar hay una contribución de solo 10€ por persona/ clase de 2 horas (materiales incluidos, bebidas no incluidas) o de 30€ por 4 clases. Vente y hablamos. Rafa. \-\-\-\- Hi! Every day there are new ways to learn Spanish, (or any language) new apps, grammar methods, AI, teachers explaining things on videos, and they are all great. If they help you to understand more and to speak better, they are great. The main plan in this group is to improve your Spanish with games, real activities and exercises to speak more. All the games and activities are a good excuse to correct the most difficult/ frequent mistakes: Difficult words, confusing past tenses, prepositions, verbs that mean many things, ser and estar in the past, sentences with two or more verbs, subjuntive, colloquial expressions, and also “cultural" mistakes: How we, Spanish people, use the language in different situations? People participating are (almost always) very nice, and usually leave very positive reviews of the classes. If the plan fits you, come to practice your Spanish and we'll talk about food, travel, work, culture, Internet, local issues, business, news and many more things. There is a contribution to participate of only €10 per person/2-hour class (materials included, drinks not included) or €30 for 4 classes. Let´s talk. Rafa.
