Esto no es un evento al que te sumás. Es una propuesta distinta: **👉 preparo un kit para que armes tu propia juntada (picnic o mateada, al aire libre o en casa) con amigos.** Yo no participo del encuentro. **Un Kit Sabores & Conexión que incluye:** 🍰 postres caseros para compartir 🧉 mate, bombilla y yerba 💌 tarjetas con dinámicas de conversación 🍽 servilletas, cucharitas y todo lo necesario Todo pensado para que no tengas que ocuparte de nada. La idea nació de algo muy lindo que pasó hace unos días. Personas que se conocieron en mis encuentros se volvieron a juntar por su cuenta, simplemente porque tenían ganas de verse. Yo acompañé ese encuentro con un pequeño kit… y ver lo que pasó me llevó a crear esta propuesta. *No es solo comida.* *Es una pequeña experiencia pensada para compartir y para que pasen cosas que no estaban planificadas.* **¿Cómo funciona?** Vos elegís el lugar, te organizás con tus amigos, y yo preparo todo. **💫 Valor: 36.000** Para compartir entre 6 a 8 personas (aprox. 4.500 – $6.000 por persona) **Si te interesa** o te da curiosidad, podés **escribirme por WhatsApp** y lo vemos juntos: **11 6220 1726** 🎥 Mira en IG video explicativo: http://bit.ly/4bCNdx9 Carolina ⚠️ Nota: la fecha publicada es solo de referencia. 👉 La fecha publicada es solo de referencia para poder organizar pedidos para el fin de semana largo ------------ This is not an event you can join. It’s a different kind of proposal: **👉 I prepare a kit so you can create your own gathering (picnic or mate-style, at the park or at home) with friends.** I don’t attend the meetup. **A Sabores & Conexión kit that includes:** **🍰** homemade desserts to share 🧉 mate, yerba and bombilla 💌 conversation cards 🍽 napkins and small utensils Everything is prepared so you don’t have to take care of anything. This idea came from something really beautiful that happened recently. People who met at my gatherings decided to meet again on their own, simply because they wanted to reconnect. I sent them a small kit… and what came out of it inspired this. *It’s not just food.* *It’s a small, thoughtful experience designed to be shared* *and to let unexpected moments happen.* **How it works:** You choose the place, you gather your friends, and I prepare everything. **💫 Price: 36,000 ARS** For 6 to 8 people (approx. 4,500–6,000 ARS per person) **If you’re interested or curious,** **feel free to message me on WhatsApp:** **📱 +54 9 11 6220 1726** 🎥 Watch a short explainer video on IG: http://bit.ly/4bCNdx9 Carolina ⚠️ Note: The date shown is for reference only. 👉 It’s there to help organize orders for the long weekend.

Give it a try!” - *Brenda* 🗣 "It’s a wonderful experience, it’s like being a kid again, when you were at the park, playing with other kids, and just decided you were going to be best friends for the next hours. Maybe you’ll never see those kids again. But that hour was amazing because you both opened up and trusted each other." - *Sara* [More Google reviews here 👈](https://www.google.com/maps/place/EPIC+LLAMA/@29.4255256,-41.3746386,3z/data=!4m6!3m5!1s0x41cb49107d35788f:0xf758abc88e22289c!8m2!3d29.4255256!4d-41.3746613!16s%2Fg%2F11swcv3hw2?entry=ttu) **🤓 FAQ** **• Can I come alone?** Of course, we encourage it :) 99% of people do! **• I signed up but never got an invite.

The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** Web Forms gave .NET developers a powerful abstraction for building reusable UI controls long before design systems were a thing. Web Components finally bring that same idea to the browser natively. This session explores how the Web Forms mindset translates into Custom Elements, Shadow DOM, and HTML templates. We’ll examine how Web Components enable design systems that work across frameworks, how they differ from server‑driven controls, and why they’re becoming a foundational layer for modern UI. Whether you’re maintaining legacy apps or building greenfield projects, you’ll leave with a practical understanding of how to apply familiar patterns in a modern, standards‑based way. **YouTube Link** TBA
